Yedigöller National Park (Turkey’s “Seven Lakes” park) is a remote and tranquil treasure in the Bolu Province.

Is Yedigöller National Park Worth Visiting? A Quick Answer for the Impatient Traveler

Yedigöller (Seven Lakes) stands out among Turkey’s nature parks for its quiet beauty, especially in autumn. In a sentence: Yes, it is generally considered worth a visit for nature lovers and outdoor photographers. The park’s core attractions are its seven mountain lakes and intact forest. These glacial (landslide-formed) lakes – named Büyük Göl, Nazlıgöl, Sazlıgöl, İncegöl, Küçükgöl, Seringöl and Deringöl – lie in a high-elevation forest basin and are framed by primeval beech and fir woods. The most famous image of the park is the forest in peak autumn color, when reds, oranges and yellows blaze around the lakes. Even outside fall, visitors report a profound stillness and lush greenery: “One can always enjoy the silence of nature and feel absolute serenity here”. The lakes themselves are undeveloped and usually free of crowds, offering a sense of wilderness. Wildlife is also thriving under protection: deer, boar, foxes, even wolves and brown bears are known to roam here.

On the other hand, Yedigöller is quite rural and rustic. There are no big hotels or resorts; only a handful of simple bungalows, a campground, and a cafe. Visitor facilities (toilets, restaurants) are minimal compared to more touristed parks. Access roads wind through mountains and can be bumpy or closed in winter. In short, Yedigöller rewards patience and preparation: if you go expecting a pristine forest escape and come ready for basic camping or cabins, it delivers. If you require luxury or broad amenities, it may feel too basic. Most travel writers who have been here emphasize its unique charm in autumn, with dozens of local guides and blogs declaring fall (late September to October) “magical”. Spring is a close second (with blooming wildflowers). Summer is lush but can be busy, and winter is snowy and adventurous (many roads are closed).

Yedigöller will likely delight anyone seeking unspoiled lakes, forests and low crowds. It may not thrill those who want city-like comforts. In the sections that follow, this guide will cover everything a visitor could ask: the exact location, how to get there, descriptions of each lake, seasonal differences, trails, camping rules, lodging options (bungalows, camping, nearby hotels), dining, what to pack, safety and entrance fees. For someone planning a trip, it aims to be the only guide needed, with data and tips far beyond what existing blogs or brochures provide.

The Seven Lakes of Yedigöller: A Visual and Descriptive Journey

Yedigöller’s very identity rests on its seven mountain lakes, all formed by landslides that dammed streams long ago. They lie in a roughly north-south sequence within two terrace plateaus, each lake spilling into the next (except in winter). The official names and order of the lakes, going from the south end of the valley northward, are: Sazlıgöl, İncegöl, Nazlıgöl, Büyükgöl, Küçükgöl, Seringöl, and Deringöl. A small eighth pond, Kurugöl (“Dry Lake”), often dries up and is less notable, so it is usually omitted from lists. The Turkish names, translated, hint at each lake’s nature: Büyükgöl = Big Lake, Küçükgöl = Small Lake, İncegöl = Slender or Long Lake, Nazlıgöl = Coy Lake, Sazlıgöl = Reedy Lake, Deringöl = Deep Lake, and Seringöl = Cool Lake (or simply a name). The largest lake by area is Büyük Göl, and the deepest is Deringöl. They range from mirror-like ponds in shaded forest to open-water pools flanked by hills.

Below we describe each lake’s key traits. Together they form a wild mirror-scene, with sunrise and sunset light turning their still surfaces to gold or crimson.

• Büyükgöl (Big Lake) – As its name says, this is the largest lake in the park. Covering about 25,000 square meters, Büyükgöl holds more open water than any other. It lies in a wide shallow basin at the southern end of the upper plateau (around 780 meters elevation). Tall old beeches and oaks line its shore. Büyükgöl is the most accessible lake – often the first lake many visitors reach when driving into the park and it has the main camping and restaurant area nearby. On clear mornings it often reflects the surrounding trees and sky. A jetty and picnic spots have benches, making it a gathering point. Viewpoint: The hillside above Büyükgöl is dominated by the wooden Habitat Mesire (picnic) area, which includes bungalows, campsite, and the forest café. You can climb nearby trails to overlook the lake.
• Seringöl (Cool Lake) – This charming little lake (about 1,800 m²) is also called “Serin Göl” in Turkish. It is very shallow – only about 2 meters deep – and is famous for trees emerging from its waters, giving it a fairy-tale quality. Seringöl sits just north of Büyükgöl, on a slightly lower terrace, so one can walk downhill from Büyükgöl to reach it easily. It is often the first lake encountered on foot when coming on foot from the village side (Mengen road) into the park. Despite its small size, Seringöl is a photo favorite because of the tranquil scene of glossy green water dotted with logs and framed by forest. The little waterfall at its outlet is also picturesque. Note: Seringöl’s banks are a popular camping spot in mild weather (signs mark allowed camping zones). It is also the location of the “Çam Pınarı” nature houses and restaurant on one side, and wooden lakeside walkways on the other.
• Deringöl (Deep Lake) – True to its name, Deringöl is the deepest of the seven lakes, about 10 meters deep. It covers roughly 15,000 m², so it is also one of the larger lakes. Deringöl lies immediately north of Büyükgöl and is connected via a stream from Nazlıgöl (above). Its clear, cold water and fairly steep banks make it look like a natural pond under the forest canopy. Park literature notes a wooden boardwalk here along the water’s edge, perfect for reflection shots on calm days. Anglers value it for its trout. A pleasant meadow lies nearby. Feature: According to the park’s management, the walking platform (boardwalk) at Deringöl is “ideal for reflection shots” – meaning photographers can capture the mirror image of foliage in still water.
• Nazlıgöl (Coy Lake) – Immediately upstream from Deringöl is Nazlıgöl. It is named “Coy” or “Coquettish” lake because its overflow water drips from a spring or seep at the lake’s edge and forms a small waterfall as it drops to Deringöl. In Turkish, it’s sometimes called “Şelale Göl” (Waterfall Lake) for this reason. Nazlıgöl has a surface area around 16,000 m². It is the widest pond of the seven. The little waterfall on its dam is one of the park’s photo icons – in mid-autumn or spring, a slow shutter exposes the cascading water and the surrounding ferns. A footpath leads around Nazlıgöl’s shores, and from one side you can peer over the fall. The waterfall spot is sometimes called the “Ince Tül” (“thin veil”) by photographers.
• Sazlıgöl (Reedy Lake) – A few minutes’ hike north up a gentle rise from the Visitor Center parking, you come to Sazlıgöl. As the name implies, it is fringed by reeds. Sazlıgöl’s area is about 6,000 m², smaller than the Big Lake but larger than İncegöl. It lies in a marshy basin and is shaped more irregularly than the others. Wildlife such as ducks and wading birds often frequent it. It’s next to the trail that links Büyükgöl back to the entrance area (i.e. it sits close to where you park), so it is commonly the first lake that arriving visitors see. The water is still and dark, offering perfect mirror reflections of the surrounding hazel and beech trees. In spring, water lilies can bloom on its surface.
• İncegöl (Slim Lake) – Heading further north, the next lake is İncegöl. Its name means “Thin Lake” and indeed it is a long, narrow pool. With an area of only about 1,000 m², İncegöl is by far the smallest of the named lakes. It lies at the very entrance of the park: as soon as you enter the forest road area, a parking lot below gives access to İncegöl. From above, one can view this elongated pond lying amid a green clearing. Because it is at 900 meters elevation (about 100 m lower than Büyükgöl), its shores have a lush, almost subtropical feel in summer. In spring, it is the first area to display wildflower color. Feature: Some guidebooks refer to İncegöl as the “gateway” to Yedigöller’s nature, since almost everyone passes it first upon entry.
• Küçükgöl (Small Lake) – Right upstream of İncegöl and just north of Sazlıgöl sits Küçükgöl. True to its name, Küçükgöl is a small mirror pond, only a few hundred square meters in size. It is tucked against a hillside and often goes unnoticed by hurried visitors, who are busy with the larger lakes. Nonetheless, in autumn its little rim of beeches turns bright gold, making a pretty intimate scene. (Official sources do not give its exact area, but it’s typically listed alongside the others as one of seven.) A map indicates a modest clearing next to it, but there are no formal facilities here. You might see small trout or frogs, and in spring delicate marsh plants by the shore.

Combined, these lakes stretch over roughly 1.5 kilometers north–south and span two terrace levels about 100 meters apart in elevation. The entire “Seven Lakes” sequence rises through a forest valley. The southernmost lake on the upper platform is Büyükgöl; the northernmost (except Kurugöl) is Deringöl. Most lakes are connected by streams, so in spring and winter you might even see them leak or flow one into another (though in dry months some spillways fall silent). Notably, Nazlıgöl drains into Deringöl, whose outflow goes to Büyükgöl; separately, Seringöl and İncegöl drain toward the Sazlıgöl side.

Across all seasons, the lakes provide the visual centerpiece of the park. In spring, you’ll see the water level full and lakes edged with fresh green. By summer, tree cover is dense and the lakes glint in light openings. In autumn, each lake turns into a tableau of oranges and reds – for instance, reflections of golden birches in Sazlıgöl, or of crimson beeches above Nazlıgöl. In winter, many lakes partly freeze or are surrounded by snow, making a stark white-and-green contrast. In all cases, the undeveloped nature of the lakes (no concrete dams, few visitor facilities at the water’s edge) means you can usually find a quiet spot for your camera or picnic. As one local travel source notes, the lakes are “charming simply because they are undeveloped and are never crowded with cars, buses or people”.

Therefore, the “Seven Lakes” are not just a list of names – each one has its own character and best viewpoint. In planning your visit, you might start with the lower lakes (İncegöl, Sazlıgöl) right at the entrance, then hike or drive northward to Büyükgöl and beyond. Every lake is accessible by short trails; some have picnic tables or cabins nearby. At least one lakeside campsite is marked (by Big Lake), and there are footbridges linking to photographing angles (especially at Deringöl). This guide will refer back to these lakes in sections on hiking, photography, camping, and lodging below, so you can see how to make the most of each one.

When is the Absolute Best Time to Visit Yedigöller? A Seasonal Breakdown

Yedigöller’s appeal changes dramatically with the seasons. Visitors in mid-October will experience a very different park than those in mid-April or January. We review each season below, noting weather, foliage, crowds, and activity tips. Bear in mind: Turkey’s climate is shifting, but averages are as follows for Bolu’s region (the park sits roughly at 900 m altitude):

• Autumn (September – November): The ultimate season. By far the most lauded time. Starting in late September, deciduous trees turn vivid hues of orange, red, gold and purple. This “symphony of colors” offers unparalleled photo opportunities – reflections of colored leaves in the lakes, carpets of foliage on trails, and golden light in forests. Many sources highlight mid-October as peak, when oaks and beeches blaze before dropping their leaves. (Park management even advertises an “Autumn photo safari” as a featured activity.) Temperatures are usually mild: daytime highs around 15–20°C (60–70°F) and nights cool but above freezing. Rain is possible, but heavy snow is rare until late November. The weather is generally ideal for hiking and camping — cool but not freezing, and days are still fairly long. The tradeoff is crowds: weekends in October can see many day-trippers (especially from Ankara/Istanbul) for the peak colors. If possible, midweek visits avoid the worst crush of local visitors. In any case, you should book lodging well in advance for autumn weekends, as accommodations fill up. In summary, autumn delivers* dramatic beauty and is the top recommended time to come.
• Spring (April – June): The awakening of nature. As snow melts and days lengthen, spring in Yedigöller is also splendid. Late April and May see profusions of wildflowers carpeting the forest floor – early tulips, violets, and alpine plants (the park even has local snowdrop and crocus species). The temperature range is comfortable: about 15–25°C (60–77°F) during the warmest daytime. Orchards of blossoming wild cherry or apple may bloom near the park edges, and tree buds give a soft green haze to the woods. Bird song is frequent. Streams flow briskly from mountain snow, making the lakes nearly full. Hiking is excellent as trails drain quickly and are not yet muddy. Nights can still be chilly (5–10°C) so a warm jacket is needed, especially for camping. Importantly, spring sees fewer crowds than autumn; you can often enjoy serenity and solitude. There are still enough daylight hours, though daylight is noticeably shorter than in summer. For camping, remember that late spring rains can come (pack a rainfly). In short, spring is a close second to autumn for scenery. It lacks the intense fall colors, but it has its own wildflowers, and it feels like nature “waking up” with bright greens and rushing streams.
• Summer (July – August): Green and lush, with warm days. Summer in the park brings full leaf cover and warm, even hot weather. Daytime highs often reach 25–30°C (mid-70s to 80s °F), though nights cool off in the forest. The park’s altitude keeps it from getting as hot as plains. By July, the entire area is emerald-green. It is an excellent time for wild swimming (though swimming is not officially allowed – see FAQ) and for fishing (trout are abundant). Most of the park’s facilities (campground, café) are open. Summer has the longest daylight. However, this is also when mosquitoes and ticks are most active in forests, so insect repellent is a must. Another drawback of summer is that tourist numbers can rise, especially in mid-July/August weekends when Turkish families go on vacation. The park’s small campsites and walkways can feel crowded then. Late August can get very dry; fall fire restrictions sometimes begin. If visiting in summer, plan to hike early morning or late afternoon (to avoid midday heat and crowds). Also pack plenty of water.
• Winter (December – March): A snowy wonderland for the hardy. Yedigöller in winter is a true Nordic experience. By December, the park is often blanketed in snow: all roads and trails become white, and many tourists do not come. Average temps hover around 0°C (32°F), dipping lower overnight. A typical January or February day might see -5°C morning, 5–10°C afternoon. Park management notes this is a time for “a white fairy-tale atmosphere”. The lake surfaces partially freeze. If you have snowshoes or cross-country skis, the woods provide pristine cross-country tracks. Southern Bolu is famous for its winter resorts (Kartalkaya ski area is an hour away), so combining a ski trip with a snowy Yedigöller hike is possible. Road access: Crucially, the Bolu–Yedigöller road on the west side is closed in winter. Only the route via Yeniceağa–Mengen (the east side) stays open. Even then, chains are mandatory on the final twisting 42 km road. Many travelers avoid renting cars and instead hire a 4WD or join a guided excursion in winter. Facilities inside the park are mostly shut down (the cafe may close). However, the upside is extremely low visitor numbers and absolutely quiet, crystal landscapes. Always check local weather and road conditions and carry winter gear. We’ll discuss details in planning.

Best time summary: For most visitors, mid-September through October is ideal for the full autumn spectacle. If you prefer fewer crowds or want wildflowers, consider May. Summer is fine if you want warm hiking and fewer fireworks about colors. Winter is only for the adventurous prepared for snow. We will frequently note in the sections below which times of year particular activities are recommended (for example, photography is usually easiest in autumn/spring with clear skies and color). Weather-wise, always pack layers: even in summer it can drop 10°C at night, and even in fall/winter a sudden rain or snowfall can occur.

Your Ultimate Guide to Things to Do in Yedigöller National Park

Once at Yedigöller, visitors find a well-rounded set of activities: hiking, photography, camping, wildlife-watching, picnicking, and some fishing. There are no amusement rides or major attractions – the “activities” are basically outdoor pursuits in forest and lakeside surroundings. Below we break these down in detail. The first section is on hiking and trekking, followed by photography, then camping, picnicking and relaxation, wildlife/birding, and fishing.

Hiking & Trekking: The Best Trails for All Levels

Yedigöller has no paved roads through the forest (aside from the main car approach). Instead, there are marked foot-trails linking the lakes and ascending nearby hills. Trails range from an easy paved loop around Büyükgöl to challenging forest routes. In general, expect graded dirt paths and wooden boardwalks; some steep staircases or switchbacks exist, but no ropes or technical climbing is needed. Signposts at junctions are sporadic but generally present. Mobile phone reception is spotty, so bring a map or GPS. Common advice is to wear sturdy walking shoes or hiking boots, as trails can be muddy or rocky. Below are the recommended routes, from easiest to hardest:

• The Main Lake Loop (Easy, ~5–7 km, 2–3 hours): This is the most accessible hike, suitable for families and casual walkers. It typically starts/ends at Büyük Göl (the main lake’s car/camp area) and makes a loop via İncegöl/Sazlıgöl. The path follows the park’s interpretive loop: first a stroll along the forest road by the lakeshore, then a short overland forest trail, and back on a dirt road. You’ll pass Büyükgöl, then Seringöl and Deringöl in sequence, curving past Küçükgöl and Nazlıgöl if you include the longer variant, and finally return via Sazlıgöl and İncegöl by another route. In total it is roughly 5–7 km depending on route choices. Elevation gain is minimal (mostly rolling hillside). This loop reveals all the main lakes and forest scenery without any very steep climbs. It is wheelchair-accessible at Büyükgöl lakeside (paved path), but after that terrain is natural. According to one hiking guide, the trail is about 7 km long and takes 3–4 hours. (This is reasonable if you include breaks; fit hikers might do it in under 2 hours.) Along this loop you’ll get lake-view vistas, the wooden Deringöl walkway, and maybe glimpses of wildlife in shaded meadows.
• Kapankaya Viewpoint Trek (Moderate, ~3 km, 1–2 hours): For a panorama of the entire Seven Lakes basin, the short hike up to Kapankaya peak is the highlight. Kapankaya is a rocky outcrop in the middle of the park, with a wooden viewing platform built on it. From that tower one can see all seven lakes lying below. The trek begins near İncegöl or at a parking area marked for Kapankaya. The trail quickly steepens (several hundred meters of elevation gain). It is steep and uses many steps cut into the slope. Hikers note it is “moderate” difficulty – not technical but certainly strenuous on the legs. (Tripadvisor comments warn of steep ramps and a narrow road, likely referring to this route.) Plan about 1–2 hours roundtrip. The payoff is a breathtaking bird’s-eye view. On a clear day the panorama stretches across green forests and the glimmering line of lakes. The National Parks brochure specifically mentions “the wooden balcony” at Kapankaya, which offers a rare viewpoint including all seven lakes in one sight. Sunrise and sunset from Kapankaya can be magical (though it requires hiking up in the dark or late evening, which is only for the very prepared). A few benches have been placed near the peak so you can sit and admire the scene.
• The Complete Seven Lakes Circuit (Challenging, ~15–18 km, 6+ hours): For experienced hikers with a full day, the full circuit of all seven lakes (and more) is possible. There is no single maintained trail around every lake, so this route requires combining several paths and some walking along forest roads. A typical long-loop might start at İncegöl, go up to Kapankaya, descend to Büyükgöl, then continue via Deringöl-Nazlıgöl, cross the dam to Seringöl, loop behind to Küçükgöl and Sazlıgöl, and finally return to İncegöl. This encompasses nearly 18 km and involves perhaps 300–400 m of total elevation gain. It passes through varied terrain: boardwalks at Deringöl, stony switchbacks to Kapankaya, and both shaded meadows and dense forest. This is only for fit hikers with navigation skills. On foot, the lakes can appear deceptively far apart. There is little cell signal on the trails, so carry a GPS or offline map. In winter, this route would be icy or deep in snow, so it is best done April–October.

(Other trails): In addition to these main loops, shorter out-and-back hikes exist. For example, a popular little diversion is to walk the swampy trail along the Sazlıgöl shore, where wildflowers bloom in spring. Another is to follow the stream from Nazlıgöl downstream to Deringöl, observing water plants. The paths are well trodden, so it is usually hard to get lost as long as you stick to clear trails. Local visitors sometimes take unmarked shortcuts between lakes, but we do not recommend venture off-trail. Trailheads and Signs: The main trailhead for all hikes is the parking area by İncegöl (the entrance). There are few formal signposts, so look for the park logo on directional signs. Many paths are dirt, and in wet weather boots are strongly recommended (the forest floor can be slick with leaves or mud). Fall is arguably the most photogenic time, but spring’s wildflowers (primroses, anemones, cardamines) also make any hike memorable.

The Main Lake Loop (Easy)

• Length: ~5–7 km (3–4 miles)
• Time: 2–4 hours (depending on stops)
• Difficulty: Easy (mostly flat trails and dirt roads)
• Highlights: Views of İncegöl, Sazlıgöl, Büyükgöl, Deringöl; reflections on the wooden Deringöl walkway; the Pisagor Tree by Büyükgöl (two beech trunks meeting at 90°, a park curiosity).
• Trail Description: From Büyük Göl’s picnic area, follow the lakeshore path north toward Seringöl (a short detour brings you there), then continue uphill to Deringöl via a minor trail. Take the Deringöl boardwalk (nice for photos) and then loop back west, crossing the dam at Nazlıgöl, then down to Büyükgöl. The return leg skirts Sazlıgöl’s edge and passes İncegöl on the way back to the start.

Kapankaya Viewpoint Trek (Moderate)

• Length: ~2–3 km roundtrip
• Time: 1–2 hours
• Difficulty: Moderate (steep climb)
• Highlights: The seven-lake panorama from the Kapankaya overlook.
• Trail Description: Starting near İncegöl’s parking or from Büyükgöl (there are signs for Kapankaya in the park), climb the marked path up the hill. The switchbacks are steep but well-cleared. Shortly you reach the wooden viewing platform (Kapankaya Seyir Terası). One side of the platform looks north at the lake system, and the other side looks south back down the forest valley. On a clear day you can see all seven lakes at once. The trail loops back the way you came, or you can descend via a slightly different path on the opposite side of the ridge to form a short loop (about 3–4 km total).

The Complete Seven Lakes Circuit (Challenging)

• Length: ~15–18 km (9–11 miles)
• Time: 6–8+ hours (full day)
• Difficulty: Hard (long distance, some uphill, requires navigation)
• Highlights: All the above, plus remote forest, and a variety of ecosystems across the park.
• Trail Description: For hikers seeking a full day out, one option is a clockwise trek: start at İncegöl (entrance), hike up to Kapankaya, back down to Büyükgöl, then follow the loop trail through Deringöl and Nazlıgöl, cross Nazlıgöl’s dam, continue to Seringöl, skirt past Küçükgöl, loop by Sazlıgöl, and return to İncegöl. Note that some segments (like between Nazlıgöl and Seringöl) may require following unpaved roads or forest paths that aren’t fully signposted. Bring plenty of food, water, and mapping tools.

Photography: Capturing the Magic of the Seven Lakes

Yedigöller is a photographer’s paradise, especially for nature and landscape photography. Each lake and season offers unique compositions. Here are some tips and highlights:

• Autumn Foliage Shots: The classic Yedigöller shot is color and reflection. Best times are mid-October, when broadleaf trees around the lakes turn deep gold and crimson. The calm lakes act as mirrors: capturing leaves floating on water or mirrored pines in still water is striking. Sazlıgöl is especially photogenic with fall colors reflected on its surface, as mentioned by local photographers. Nazlıgöl’s little waterfall at its south end is another autumn icon – set up at a slow shutter speed (e.g. 1/4–1 second) to blur the falling water into a silky veil. The Pisagor Tree (two trunks forming a right angle, on the southwest shore of Büyükgöl) can be another photo subject with autumn leaves overhead. For best color, a slightly overcast day can saturate tones, or shoot in golden hour (early morning or late afternoon) for warm side-lighting.
• Sunrise and Sunset Spots: The lakes themselves are oriented mostly north–south, so the sun rises and sets behind them. Early morning light on Büyükgöl or Nazlıgöl can give a gentle glow on leaves. One favored spot is the east side of Büyükgöl: at dawn, the rising sun filters through the forest onto the water. At sunset, the western slopes of Sazlıgöl and İncegöl catch the last light (though by sunset many lakes are shadowed by surrounding hills). The Kapankaya viewpoint is also a prime place for wide panoramas at sunrise or sunset, if you don’t mind hiking in semi-darkness.
• Essential Gear: A tripod is almost mandatory for this park if you aim to do it justice, especially in low light. (For example, the “winter fairy-tale” looks best with long exposures.) A wide-angle lens is useful for capturing sweeping forest and lake vistas. Also consider a polarizing filter to reduce glare on the water and deepen the sky, and ND filters for waterfall shots. Boots or hiking shoes are needed if you plan to shoot at dawn in the woods (remember dewy undergrowth). Water-resistant camera protection is wise in case of rain. Because Yedigöller is relatively fog-free (it’s not on a high plain), you can expect clear visibility; misty mornings sometimes form over the lakes for atmospheric images.
• Special Scenes: In winter, if conditions allow, the snow on boughs above the lakes makes exquisite monochrome scenes. And at night, the lack of light pollution means the stars over the park are very bright – astrophotographers sometimes camp out on clearer nights to shoot the Milky Way above the lake basin.

Beyond landscapes, wildlife photography is possible too (see next section). Cameras or binoculars aimed at deer or birds in the forest can yield luck when found.

Camping: Sleeping Under the Stars in Yedigöller

Camping is a very popular activity in Yedigöller National Park. Authorities designate specific areas for camping, primarily around the shores of Büyük Göl and Deringöl. Important: In-forest or “wild” camping anywhere off these sites is illegal. The official campground at Büyük Göl is free of extra charges beyond the park entrance fee. It is a primitive camp: there are pit toilets and potable water taps, but no showers or electricity. Sites are gravel/grass clearings; you must bring all your gear. Canvas tents are allowed, and many families set up on designated gravel pads. RV/caravan camping is also permitted in that zone. (There is a small fee for power or hookups, but typically not offered in the park’s rustic campground.)

A highlight of the park’s official information is that campfire is prohibited except in provided steel bins: “All fires (including samovars) are banned, except that campers may burn wood in barrels after dark”. In other words, you cannot just light a campfire in the woods. There are communal metal fire rings or barrels at the campground; after 9 PM or so these are opened for use. Outside these spots, absolutely no flames (no camp stoves anywhere off-road). This rule is strictly enforced to prevent wildfires.

The park offers rental of full-service “nature houses” (rustic cabins and tents) through private operators by the entrance, but we focus on true camping here. If you plan to tent-camp, be prepared: the nights can get cold even in summer, and rain can come unexpectedly. One camper advises always having a rain fly. Inside the forest and near streams, mornings can be dewy and foggy – a waterproof groundsheet is useful. Also: insect repellent is strongly recommended for summer or spring camping, as mosquitoes and midges are present (the forest is moist and shaded).

Camping Etiquette: Pack in all your supplies and pack out all garbage. Do not cut or damage any trees for wood (use only dead sticks if anything). Keep voices low at night. The park’s famous silence is part of its appeal, so late-night partying is inappropriate. The campground closes at an implicit gate at night, so don’t plan to hike back in darkness.

Finally, note that winter camping (Dec–Feb) is for the truly hardy. Temperatures can be well below freezing at night, and snow can cover the ground. The campground’s toilets are often unusable in heavy snow. Yet if you have winter camping gear (four-season tent, stove, etc.) it can be magical to wake to a snowy forest. Just be cautious: there are bears and wild boar, so store food well.

Picnicking and Relaxation: Finding Your Perfect Spot

Even if you’re not overnighting, Yedigöller is designed for day visitors who want to picnic and relax in nature. At the main camp area by Büyük Göl there are picnic tables under trees and a small café (“Sincap Cafe”). Farther in, Deringöl has a few benches. Given the intact forest, nearly any shaded spot on a lakeshore is a perfect picnic location. Some recommended times/places:

• Büyükgöl Shore: This is the largest flat lawn by the water. There are several forest-bench seats and grill stands (though grilling wood is not provided). Groups often set up large picnics here. The Habitat Restaurant (see next section) also has tables under roof for shade.
• Nazlıgöl Steps: There is a small cascade on Nazlıgöl’s south edge with stone steps. People often sit by the little waterfall for a snack, enjoying the lapping sound.
• Seringöl Meadow: The grassy open area north of Seringöl has sea-of-green in summer. It’s quiet and you can lay out a blanket by the shallow lake edge.
• Forest Clearings: Occasionally you’ll see old wooden platforms in the pines above the lakes. These were once used as lookouts or picnicking decks (e.g., one at Küçükgöl). If clean and intact, they’re unique vantage points.

There are no vending machines or shops inside the park beyond a few snack stands (Habitat Restoran and Sincap Café serve food, below). Therefore, bringing your own food and water is essential for serious picnickers. Many visitors bring coolers with sandwiches, fruit, and ample drinking water (tap water is potable). July–September can be warm, so keep perishables cool. Pack matches or a portable stove if you intend to heat something, but remember open fires are banned except in provided rings. Recycling bins are sparse; carry out any trash or deposit in the few park bins (signage requests volunteers to sort recyclables).

In any picnic spot, also watch for wildlife: squirrels and birds are abundant and will investigate anything edible (so keep food covered). Respect signs that mark certain areas as protected or camping-only.

Wildlife and Bird Watching: A Guide to the Park’s Fauna

Yedigöller’s forests are rich with animal life, thanks to strict protection. Visitors have the chance to see diverse species, though many are shy. The official materials note that deer and wild boar are quite common and increasing in number. Indeed, morning and dusk are best for spotting them. Birdlife is also abundant: woodland birds like woodpeckers, tits, and nuthatches abound in the beech forests. Migratory waterfowl sometimes rest on the lakes, and you might glimpse herons or ducks. Small mammals—foxes, jackals, wildcats or even lynx—do roam but are rarely seen by casual visitors. Brown bears are present in Bolu forests (the European population), but encounters in Yedigöller itself are extremely unlikely unless you go deep off-trail. (Safety note: Do not leave food scraps; bears and boars may come if any smells are left out.)

For wildlife photography or bird-watching, bring binoculars or a telephoto lens. Some specific tips:

• Dawn and dusk are most active times.
• Listen for the “hopkırkış” alarm call of Eurasian jays (they often warn of approaching people or predators).
• The fenced deer sanctuary near Kapankaya might offer a guaranteed deer sighting, as that enclosure attracts them.
• The streams and ponds can have frogs and salamanders; a sound-recording smartphone app will tell you frog calls.

Park authorities prohibit feeding or approaching wildlife. Enjoy the animals from a distance. The in-park café and campground sometimes have signs reminding visitors that deer and bear roam, encouraging caution.

Fishing: Regulations and Opportunities

Yedigöller has a longstanding trout-farming tradition: in fact, Turkey’s first trout farm (1969) was established here. The lakes and streams hold trout (locally called “alabalık”) which anglers prize. Recreational fishing is allowed, but with strict rules. You must obtain a fishing permit from park authorities (usually a small fee at the park entrance or office). Only traditional rod-and-line fishing is permitted; no motorized boats or nets. Fishing is typically allowed only in designated areas (often Büyükgöl and Nazlıgöl have banks open to anglers). Seasonal restrictions apply during trout-spawning months (rainy winter/spring). Local information in Turkish notes that the Angler’s License can be obtained from the [Nature Conservation branch office], and you must carry it while fishing.

As of writing, the park’s official visitors’ FAQs (Millipark) mention fishing as an activity at certain spots under controlled conditions. In practice, casual visitors can often rent a fishing rod from the park bungalows area for the day. Fish cleaning should be done outside park boundaries or in disposal pits; do not leave fish entrails on-site, as this attracts predators.

Overall, fishing in Yedigöller is a quiet, solitary pastime – if you’re careful to follow the permit rules. For most foreign visitors, the novelty is trying the local trout; you’ll find “alabalık” on menus at park restaurants as well (see next section).

How to Get to Yedigöller National Park: A Comprehensive Transportation Guide

Yedigöller National Park lies in the forested mountains of Bolu Province in Turkey’s Black Sea region. The nearest major cities are Bolu (42 km south) and Düzce to the west. There are multiple travel options:

Driving to Yedigöller: Routes, Road Conditions, and What to Expect

• From Istanbul or Ankara: The park is roughly 280 km from Istanbul and 220 km from Ankara. The most common route from Istanbul is to take the O-4 (E80) highway east towards Bolu. At about 150 km from Istanbul, take the Yenicaga exit (signed “Yenicaga-Mengen”). Continue southward through the towns of Yeniçağa, Mengen, and Yazıcık. Yenicaga road meets Highway D-100 further east of Bolu, which is why some guides call it the “D100-G23 route.” From Ankara, you also take the same highway and exit at Yenicaga (D-100, not Bolu city). In either case, the journey converges on Mengen District’s roadway.
• The final stretch: Once on the Yenicaga–Mengen road, after Mengen town you will see signs for “Yedigöller Milli Parkı.” Turn onto the forest service road leading north. This is a narrow winding mountain road that ascends about 500 meters over the next 40–45 km to the park. (The route from Bolu city directly west was historically a summer road but now is closed in winter, making the Yenicaga–Mengen road the all-season route.) The last 15 km is especially twisty and steep; even in good weather it requires careful driving on single-lane curves. Winter conditions: snow and ice are common from Dec–Mar, so chains or snow tires are essential. The district governor’s office specifically advises that Bolu–Yedigöller road is a forest road subject to chains requirement, and even mentions that winter chains are mandatory on that route. Drive slowly after dark: some visit reports note animals crossing or fallen branches on the road at night.
• Road safety: Some visitor reviews call the road “quite bad” and “sometimes dangerous”. Indeed, there are steep drop-offs and narrow sections. In rain, the curves are slippery. It is safest to go during daylight and good weather. Do not attempt in a heavy storm. Also note that mobile service is spotty; it may drop out in the gorge. Emergency services can be hours away, so carry a basic first-aid kit and let someone know your itinerary.
• From Bolu: If driving from Bolu city, you would normally head north out of Bolu on highway D-100, but when you reach the Yenicaga intersection you must turn right (east) onto the Yenicaga road. In other words, you cannot go straight toward Mengen via Bolu. Bolu city to Yedigöller via Yenicaga is about 80–90 km. The government now actually tolls this: HGS (highway toll) system charges 180 TL for cars using the park road (effectively this is the entrance fee for vehicles).
• From Mengen vs. Bolu route: The road forks around the park: one route comes up from Mengen on the east side, the other (shorter but closed in winter) comes in from Bolu west. For most of the year, use the Mengen–Yenicaga approach. This is the standard route even in summer, as Bolu’s side road is no longer maintained. If you are coming via Kartepe or Izmit (southwestern approach), you may pass through Duzce and reach the park from the west near Sirna village – but check winter closures.

Public Transportation: Buses and Taxis

Public transport to this remote park is limited. In practice, it requires multiple connections:

• Bus to Bolu or Mengen: Turkey has frequent intercity buses. Major operators (Metro Turizm, Kamil Koç, Pamukkale, etc.) run buses from Istanbul, Ankara, and Izmir to Bolu city or to a stop at Yeniçağa. Once at Bolu city’s bus terminal, you need to get further.
• From Bolu to the park: On weekends, there is reportedly a public shuttle (dolmuş) from Bolu’s otogar (bus station) directly to Yedigöller. These are small minibuses timed for day tourists, departing only on weekends (seasonally). The schedule can be irregular, so check locally.
• Mengen route: More reliably, one can take any Bolu–Mengen minibüs from Bolu’s 24 Temmuz semt terminal (these run often). Tell the driver to stop at Mengen (50 km north of Bolu). In Mengen, there are local dolmuş vans that go to Yazıcık or Ayıkaya (the junction at the forest road). From Yazıcık/Ayıkaya, the distance to the park entrance is ~10 km up the mountain road, so you would need to hire a taxi or motorcycle taxi to cover that last stretch. It’s a common trick: Bolu -> Mengen dolmuş, then Mengen -> Ayıkaya dolmuş, then Ayıkaya -> park taxi. Bolu to park via this method can take 3–4 hours including transfers.
• From Yeniçağa: If a bus goes to Yeniçağa, you could similarly switch to a local van to Mengen or Yazıcık. Yeniçağa is slightly closer to the park than Bolu.
• Direct tours: Some tour operators in Bolu or İstanbul run daily excursions to Yedigöller, especially in autumn. These include transport but can be pricey, and tie you to a schedule. If convenience is paramount, an organized tour ensures you won’t have to swap buses. But this guide is focusing on self-transport, so we will not detail specific companies.
• Taxi from İstanbul or Ankara: For small groups willing to pay, one can hire a driver or share a taxi. For instance, a taxi from Ankara to Bolu is common (~150 TL), and from Bolu to Yedigöller about 350 TL one way (as of 2024). Splitting among 3–4 people can be reasonable.

Organized Tours to Yedigöller

Some specialized local tour companies offer single-day or overnight guided tours, especially to capture the autumn colors. These typically depart from Bolu, Ankara or Istanbul early in the morning, provide a minivan and guide, and return in the evening. If language or driving logistics is a problem, a guided tour is convenient. However, tours may be inflexible about time spent at each spot. Booking in advance for October on a weekend is wise, as these tours can sell out. Tour prices vary widely, but expect around 200–300 TL per person plus entrance fee (as of 2024). Check that the tour uses a 4WD or mini-bus capable of handling mountain roads in case of rain or snow.

Summary of Getting There: In most cases, visitors drive themselves via Yenicağa–Mengen. Public transport is possible but requires transfers. Once you reach the park entrance (Merkez, Yedigöller), you’ll find a small visitor center and parking. The park parking is 100–200 meters before the first lake (İncegöl). Remember to pay the entrance fee for your vehicle (10 TL car, or relevant group fee, as below).

Yedigöller Accommodation: From Rustic Camping to Cozy Bungalows

There are no conventional hotels inside the national park. Instead, lodging options include camping, bungalow cabins, and a few small guesthouses just outside. This section details each category and current pricing estimates.

The Complete Guide to Yedigöller Camping

As noted, camping is permitted only in designated areas, primarily near Büyük Göl. In addition, there are small campgrounds at Deringöl and possibly near some of the other lakes, but these have no services. The primary campground by Büyük Göl is owned by the park management. It has several dozen marked tent sites and some open areas where RVs can park. Facilities: There are rustic concrete toilets (squat style and some Western) and a few faucets with drinkable spring water. There are hand-washing sinks and an open-air hand dryer. There are no showers or washrooms. An outdoor shelter contains a communal sink and refrigerator (often locked). The campground manager’s office sometimes sells firewood in winter, but no cooking fuel is sold on site in summer (carry propane or camping gas). Electricity outlets are not generally available unless you pay extra.

According to the official 2025 fee schedule, camping by tent or caravan is covered by the general entrance fee: there is no extra charge beyond park entry. (However, chains tolls and any meal purchases are extra.) This means you pay the 10 TL car fee or 60 TL per adult at the gate, and then you may camp without further camping fees. This includes space for one tent or one vehicle. Group camping is allowed but each vehicle must pay. (The Millipark source clarifies “Çadır ve karavan kampı – Büyük Göl location free; 2025 giriş ücretleri kampı kapsar”.)

Wild Camping: Turkish law and park rules strictly forbid unregulated camping. Some adventurous hikers might consider discreetly camping by Sazlıgöl or İncegöl, but it is against park regulations. Rangers do patrol and can impose fines or even close the park for violators. Always camp at the marked site.

Campground Etiquette & Tips: As mentioned earlier, use the provided metal fire bins for any cookstove or wood fire, and only after dark. Store food securely (bears are present in the region). Take all trash out with you (carry trash bags). There is a rule that beyond a certain evening time (often 9:00 PM) all campers must only use the barrels for fires – do not start new fires of your own. Do not feed or approach any wildlife (even squirrels).

Alternative Camping Spots: Aside from the official campground, a few private “nature house” lodgings outside the park let guests tent on their grounds (e.g. Hindiba Doğa Evi on the Mengen road). These may include breakfast or other amenities but charge a site fee (~25 TL in fall). They have better toilets and sometimes electricity. We describe one example (Hindiba) below in the bunkhouse section.

Yedigöller Bungalows (Habitat Mesire Yerleri): An Inside Look

The Habitat Mesire Yerleri is the state-run lodging area on the shore of Büyük Göl. It consists of simple wooden bungalows (“bungalov”), rustic houses, and tents with beds (the exact mix changes). These lie in two clusters: one at the east end of Büyük Göl (the “Sincap Café” side) and one on the west side near İncegöl. Staying here means you have immediate lake access all day and can leave belongings behind during hikes.

Each unit accommodates 2 to 4 or 6 people. Rooms are basic: wooden walls, few tiles, electric heating, basic furniture. They are clean but minimal, more like a back-country cabin than a hotel room. Amenities usually include: sheets and blankets (no daily housekeeping), a small sink or kitchenette, and an outdoor deck with a table. Some units have an enclosed porch or fireplace inside for winter. The “Serin Evler” or “Nazlı Evler” cabins on the hill overlook the lake.

Pricing (2025 estimates): Precise prices can vary by season and inventory, but recent visitor reports give an idea. According to a 2023 account, a standard two-person bungalow costs roughly 400–450 TL on weekdays, and 450–500 TL on weekends. These quotes are from late-year blog posts, but they suggest the range. Larger units (for 4–6 people) are proportionately more expensive (the per-person cost drops when the cabin is shared). To update for 2025, some inflation may occur, but likely within ~10%. If we convert at mid-2024 exchange rates, 500 TL is about $30–$35 USD per night.

Booking: These bungalows are extremely popular. It is mandatory to reserve well in advance if you want to stay in them, especially for fall weekends. Reservations open online in late spring each year. They are run through the park’s official system (Habitat Mesire site). Many international sites (HotelsCombined, Agoda) list them as “Yedigöller Habitat Bungalows,” and sometimes show availability in summer. But for best rates and guarantee, book through the park’s reservation line or website.

Facilities: Staying in a bungalow grants easy use of the park’s restrooms and water. You also have access to the Habitat restaurant and Sincap Café at walking distance. Bungalows come with at least one parking spot.

Notable Units: A couple of the newer-style bungalows (“Nazlı Ev 7” etc.) have slightly better furnishing (e.g., satellite TV or attached bath) but at a higher price. The older ones are quite spartan. Visitors note “the Seringöl side bungalows are in better shape than those on the İncegöl side”. Also, some cabins (Pisagor evleri) are on a hill and have dramatic vistas of the lake from their porch (but require a climb).

Hindiba Nature Lodge and Other Nearby Options

Just outside the official park boundary on the Mengen road, there are a handful of private nature lodges and pensions that offer cabins or tent sites. These are not inside the national park so they charge separate rates. Examples:

• Hindiba Doğa Evi: A popular family-run lodge about 3 km south of the park entrance. They have wooden chalets and cabins, plus a field where you can pitch your tent (with optional shared tents offered). The grounds include clean squat toilets and a restaurant. In 2023, Hindiba’s owner quoted a rate of 400 TL (weekday) / 450 TL (weekend) for a two-person cottage. Their tent-camping package (with breakfast/dinner) was about 200–250 TL per person. Hindiba is more polished than the park campground and has electricity.
• Çam Pınarı Doğa Evleri: Located near Mengen, this is a well-known lodge with bungalows and restaurant. It overlooks the road and has scenic wooden decks. Room rates here in 2023 were reported around 250 TL (weekdays) / 300 TL (weekends) for two-person bungalows with breakfast. (It’s cheaper than the official park bungalows but a bus or taxi ride away from the lakes.)
• Sakintepe & Pansiyons: Others include Sakintepe (near Bolu side) and small pensions in nearby villages like Yenice or Kurugöl village. The tiny Yedigöller family pensions (in Yazıcık or Mengen) are about 80 TL per person with breakfast, ideal for budget travelers but very basic.
• Hotels in Bolu city (42 km away): If you prefer a motel or hotel with all amenities, Bolu city is the nearest urban area. It has many chain and boutique hotels (Hampton by Hilton, Mercure, etc.) in the 300–500 TL per night range. Bolu is a 1-hour drive from Yedigöller. Staying in Bolu means daily transit time, but you gain hot showers, restaurants, and shopping.

Yedigöller Bungalow Prices 2025 (with estimates)

Putting it all together: for on-site bungalows, expect roughly 400–550 TL per night for a two-person unit in 2025. Note this is per unit, so a larger group can split cost. This aligns with recent reports of 400–500 TL for weekdays/weekends. We have no official 2025 tariff yet, but park staff suggest they may adjust only slightly from 2024. For planning: count on about 500–600 TL (around $25–30) per night for a 2-person bungalow in peak times. If that is beyond your budget or availability, the off-site options (like Hindiba or pensions) start as low as 200–300 TL per person including meals.

Whichever lodging you choose, book early in the season or as soon as possible. During weekends, especially in autumn, both campsites and bungalows often sell out months ahead. The advice from local guides is to plan accommodations first, then plan the rest of the trip.

Food and Drink: What and Where to Eat in and Around the Park

Dining options inside Yedigöller are very limited. There are only two main food outlets within the park boundaries, plus vending machines:

• Habitat Restaurant (Büyük Göl): This is the larger eatery run by the park. It has a big dining hall and terrace overlooking Büyükgöl. The menu is traditional Turkish: grilled trout (caught on-site), soups, kebabs, mezze, Turkish tea and coffee. Prices are moderate by Turkish standards (as of 2024, expect a hearty meal for 200–300 TL for two). It is open roughly breakfast through dinner. The setting is rustic wood-paneled, with a fireplace in winter. You can sit indoors or on covered patios. This is the only full-service restaurant in the park, so at peak times it can get busy at meal hours.
• Sincap Café (Büyük Göl): A small café near the lodge cluster. It serves quick items: sandwiches, gözleme (Turkish flatbread rolls), and most famously homemade pastries and cakes. It also has bottled drinks, tea, and coffee. Families often drop by Sincap Cafe for an afternoon dessert break or picnic snack. It has a few tables outside with lake views. According to a website, Sincap Cafe “offers homemade cakes, pastries, jams, and house-brewed Turkish coffee”.
• Picnic Kiosks: Besides the above, there are vending machines (cold drinks, snacks) in the campground. These are sparse and not reliable, so do not plan on them.
• Bringing Your Own Food: Many visitors bring picnic lunches (turkish bread, cheese, olives, fruit) and eat at the lakeside benches or in tents. If you plan a long trek, pack snacks and water because trail cafes do not exist. The park sells picnic tables and permits their use everywhere except inside visitor centers. Note that open campfires are banned, so you cannot barbecue by your picnic unless you use a small camping stove on a picnic table.
• Local Towns – Nearby Restaurants: If you stay outside the park in Bolu, Mengen or Yazıcık, there are many eateries. Bolu city is famous for “Bolu pilavi” (chicken rice), and it has modern restaurants and cafes. Mengen (15 km south of park) is known for its chefs; a local specialty is stuffed eggs (a type of omelet dish). There are a few moderate-price restaurants in Mengen serving typical Turkish stews and kebabs. If staying at a nature lodge (Hindiba, Çam Pınarı), meals may be included. But note: after 8 PM, many places will close (Turkey has an earlier dinner culture).
• What to Drink: The drinking water in Yedigöller is very pure; faucets deliver cold spring water. Many locals refill bottles directly at park spigots. Still, some visitors prefer to bring bottled water or boil water at camps. Soft drinks and beer are sold at the park café and restaurant (beer consumption must be moderate and mostly at the restaurant). There are no wine shops or bars in the park.

Tips: If you want trout, eat it at the Habitat Restaurant – it’s guaranteed fresh. For coffee, remember the wild quiet: even the cafeteria closes early, so bring instant coffee or tea. For a sit-down nice dinner, your best bet is to drive to Bolu city the previous night or next morning.

Planning Your Trip: A Practical Checklist

This section consolidates logistical details every visitor needs: fees, what to pack, rules, and safety. Think of it as the final pre-trip checklist.

Yedigöller National Park Entrance Fee 2025

Starting in 2025, Turkey’s national parks now charge separate fees for pedestrians and vehicles. According to the official 2025 schedule:

• Walking Visitors: 60 TL per adult (students 30 TL).
• Vehicle Passengers (HGS toll included): 180 TL per car, 120 TL per motorcycle/ATV. (This replaces the old 10 TL car toll.)
• Bicycles: 60 TL (they now even charge bikes).
• Minibuses (≤15 seats): 540 TL; Buses: 1,800 TL.

Families should combine tickets: if arriving by car, you pay the 180 TL at the entrance booth and can have up to 4 people in the car with that one fee (presuming they allow family in car as one). Single hikers pay per person at the gate. Park rangers will issue a combined wristband or token. There is no separate camping fee – bringing a tent is included. (A printed FAQ confirms “Çadır ve karavan kampı, 2025 giriş ücretleri kapsamında ek bedel gerektirmez” – camping is covered.)

Note: These fees are subject to change, but the above are the official rates as of June 2025. Keep small bills; the booth may not make change for a large note. Car locks and paperwork may be checked at gate.

What to Pack for Yedigöller (For Each Season)

Given the remote, changing environment, packing well is key. Essentials include:

• Clothing:
  • Autumn/Spring: Layered clothes. The days can be warm (15–25°C) but nights and mornings chilly (near 5–10°C). A fleece jacket and waterproof layer (rain jacket) are musts. Sturdy walking shoes or boots (trail boots) are highly recommended as trails get muddy after rain. Hat and gloves by late October.
  • Summer: Lighter shirts and a hat for sun. However, pack a light long-sleeve shirt as mosquitos and ticks are present. Rain can come in July/August too, so a compact rain shell. Socks and hiking shoes are still advised (forest can be uneven).
  • Winter: Full winter gear – insulated waterproof jacket and pants, thermal layers, gloves, wool hat, sturdy snow boots with grip. Snowshoes or microspikes may be needed if deep snow. Even in shelter, the cabins can be cold, so pack a sleeping bag rated to at least -5°C.
• Camping Gear (if applicable): Tent with a rain fly, warm sleeping bag, foam pad, camping stove with fuel (no open fires). Headlamp or flashlight with extra batteries (power may be out in evening). Insect repellent (summer) and bear-proof containers or bags for food.
• Food & Water: Bring at least 2 liters of water per person per day (and purification tablets if reusing tap water). High-energy snacks like nuts and bars for hiking. If camping, plan your meals (sandwich makings, instant soup, etc.). A small cooler or insulated bag for perishable food is useful.
• Miscellaneous:
  • A first-aid kit (include band-aids, antiseptic, any personal meds).
  • Sunscreen and sunglasses (even in forest, UV is moderate).
  • Binoculars or camera with telephoto (for birding/wildlife).
  • A paper map of the trails (or downloaded offline map on smartphone).
  • Mobile phone (note: signal is spotty, but may work near entrances). A power bank is useful.
  • Cash in Turkish Lira (many vendors and the park entrance are cash-only). (20 TL-100 TL bills can be hard to break; bring at least some small change.)
• Optional: A portable camping chair or stool, a mug or portable cup, deck of cards or book for downtime, trash bags for packing out waste.

Remember Leave No Trace: bring a bag for trash, never litter, respect posted signs.

Park Rules and Regulations

Key rules to know:

• Fires: Prohibited except in campfire pits. As above, no open flames outside designated barrels. Gas stoves are allowed anywhere outdoors, but use them responsibly (stability, flame out).
• Dogs: Pets are not allowed inside the national park (with rare exception of service dogs). This is a strict conservation policy. Check signs and do not smuggle pets in.
• Picking Plants/Wildlife: It is illegal to pick or disturb wild plants, mushrooms, or animals. Everything grows undisturbed here. Collecting firewood from live trees is forbidden – use only dead fallen wood if you absolutely must (though even that is discouraged).
• Drones: Drones are banned unless you have official permission. The park is a no-fly zone under law, and authorities impose heavy fines for illicit aerial filming. (Use drones at your own risk.)
• Fishing: Requires a permit (see above). Catch-and-release is generally expected except for a small personal meal portion. Always carry the permit papers on you while fishing.
• Camping: Only in marked sites; otherwise you could be fined or expelled. Quiet hours are enforced (no loud music, shouting at night).
• Litter and Waste: Carry out all garbage, even biodegradable scraps. Sanitary pads and waste must be packed out or disposed only in toilets. Public bins are few; plan to bring a bag for trash.
• Firearms/Fireworks: Strictly forbidden. (This is a protected area.)
• Cycling: Bicycles must pay the bicycle entrance fee (60 TL) and are only allowed on the main road, not on hiking trails.

Respect all posted signs. Park rangers (from the Forestry Service) can issue fines for violations. By following the rules, we help preserve Yedigöller for future visitors and the flora/fauna that depend on it.

Safety and Emergency Information

• Weather: Mountain weather can change rapidly. Check the forecast for Bolu/Mengen (the park climate is similar) and be prepared for rain or even snow outside summer.
• Trail Conditions: After heavy rain, trails can be muddy; after snow, trails may be covered or icy. Slipping or ankle injuries are possible on uneven ground. Trekking poles can help stability.
• Wildlife: As noted, brown bears and wolves exist in Bolu forests, but are rarely encountered in the park’s daytime. Still, if camping, store food securely (in containers or in a bear-proof locker if provided). Keep distance from any boar or deer you do see.
• Medical: The park has no medical facilities. The nearest hospital is in Bolu city, 1 hour south. Carry a cell phone and numbers of local emergency services (Turkey’s emergency number is 112). A minor first-aid kit is essential.
• Guides/Contacts: There is a park headquarters at the entrance with a small visitor office (check opening hours; usually 8am–5pm). Staff there can answer questions or call for help. If you are hiking or camping, consider leaving word with the office about your plans.
• Road Accidents: Be cautious on the road’s hairpin turns; if you see a hazard or accident, call 112. Carry a spare tire and basic tools in your car.

Following common sense safety – staying on trails, watching your step, staying aware of changing weather – will keep your trip trouble-free.

The Natural World of Yedigöller: Flora and Fauna

The seven lakes basin is ringed by primeval mixed forest. Official sources describe it as a “living herbarium” with over 236 species of plants. Tall beech trees (kayın) dominate many slopes, creating smooth gray trunks and a high green canopy. Interspersed are oaks, hornbeams, and rowans; at lower edges, hazels and maples. Conifers (fir, spruce, and pine) also occur, especially on higher ridges. In fact, the park’s forests include Turkey’s native Abies nordmanniana (Nordmann fir) and silver fir. In spring, understory wildflowers abound – including local endemic snowdrops and crocuses. By summer, the understory is rich with ferns, grasses, and herbaceous plants. Mushrooms (edible and otherwise) grow freely in fall (but picking mushrooms is legally restricted).

This mixed forest provides food and cover for wildlife. Mammals include red deer and roe deer (often seen at dawn/dusk), and a healthy number of wild boars. Smaller mammals like wild boar piglets, foxes, badgers, hedgehogs, and squirrels are common. Occasionally hikers spot a brown bear footprint or scat; bears do exist here but tend to avoid humans. The elusive Eurasian lynx and golden jackal are possible in deep woods but rarely seen. The park has designated a 14-hectare deer sanctuary, where roe deer are bred and sometimes become tame, so you may even see deer grazing close to trails near Kapankaya.

Birdlife is diverse: wood warblers, jays, and tits flit in the canopy. Raptors such as buzzards and owls patrol above. Migratory waterbirds can appear on the lakes in spring and autumn. Herons or kingfishers might fish at the lake edges. In summer evenings, you may hear nightingales or cuckoos in the thickets. Amphibians like tree frogs are abundant in the marshy northern lakes (listen for their calls at night).

In short, Yedigöller is an ecological hotspot of Turkish Black Sea region. The protected status has allowed even apex species to thrive. For nature enthusiasts, just sitting quietly by a lakeshore often yields the sight of a deer emerging from the woods, or the sound of woodpeckers hammering on distant trunks. Remember though that wildlife is wild – observe, photograph, but do not feed or chase the animals.

The History of Yedigöller National Park

The Yedigöller lakes themselves are the result of natural landslides along a branch of the North Anatolian Fault. Geologically, these debris dams formed the lakes many centuries ago. Human history at the site intensified in the 20th century. In 1965, the Turkish government officially declared 1,623 hectares around the lakes as Yedigöller National Park, with the aim of preserving its unique nature. This made it Turkey’s fifth national park. From its inception, authorities prohibited logging and hunting here.

Shortly after the park’s creation, it also became the site of Turkey’s first trout farm (1969). Chilled, oxygen-rich waters of the lakes and streams proved ideal for rainbow trout cultivation. To this day, aquaculture (alabalık) remains part of the park’s function, and trout are stocked in the lakes and eaten by visitors (the restaurant’s signature is fresh grilled trout).

Infrastructure followed slowly: the first wooden huts and basic road improvements came in the 1970s and 80s. The road from Mengen was built in 1980s. The park headquarters and ranger station were established in the 1990s. In recent years, modest camping facilities and a park-run visitor center have been added. A major upgrade came in the early 2010s when the bungalows were standardized and signed. Throughout this, however, development has been minimal by design.

Yedigöller’s preservation success is often noted: by effectively banning hunting and logging, wildlife here has flourished relative to many parts of rural Turkey. Tourism has grown only slowly, thanks to deliberate control of construction inside the park. Therefore, while it is a “tourist” site, it remains much closer to a true wilderness than many other national parks that allow lodges and extensive vehicle access.

In sum, Yedigöller reflects a mid-20th-century conservation ethos: protect scenic nature for public enjoyment, and keep human impact light. Its “history” since designation is mainly the incremental addition of trails, modest facilities, and visitor services — but always with an emphasis on natural integrity.

Yedigöller for Different Types of Travelers

While Yedigöller appeals to a broad range, different travelers will have different experiences and needs. Here is how families, couples, solo backpackers, and adventurers might make the most of it:

• Families with Children: Yedigöller can be enchanting for kids who love the outdoors. The easy main loop (5–7 km) can be shortened to just the Büyük Göl – İncegöl circuit for little legs. Young children will delight in pond-dipping (with buckets) at Seringöl or watching ducks. Picnic lunches by the lake and staying in a bungalow (instead of camping) can make the trip more comfortable. Parents should note the strict fire rules (no campfires on convenience) but the campground does have safe toilets. Family-friendly highlights include meeting any tame deer in the sanctuary, feeding ducks (with corn kernels you bring), and hot chocolate at the café. During school holidays (late July, early August), expect more local families at the park, especially on weekends. We recommend scheduling weekday visits or very early mornings to avoid crowding if peace is desired. Life-jackets are not provided by the lakes, so keep an eye on small children near water.
• Couples and Romantic Getaways: For a couple, Yedigöller offers quiet romance in nature. A stay in a lakeside bungalow or a quiet tent under stars can be memorable. Sunrise or sunset walks to Nazlıgöl waterfall or along the pier give intimate moments. The Kapankaya viewpoint is an auspicious spot for a proposal or anniversary photo. In autumn, cozy up with a flask of tea and watch the leaves fall. In winter, some couples even come for “snow camping” or to stargaze by a wood stove, although that is for experienced outdoorsy people. Note that night-time can get cold and damp; a fireplace or heaters in a cabin can be worth the extra cost.
• Solo Travelers and Backpackers: Yedigöller is safe for solo backpackers. Turkish people are generally friendly and helpful. As a solo hiker, you might meet other trekkers on trails, or park staff. Staying in the communal campground or dorm-like beds (if available) can be a way to meet others. Solo walkers should be especially prepared with maps and let someone know their hiking plan, since cell service is patchy. Bicycle touring is another option: cyclists can reach the park and pay the bicycle fee (60 TL) and then push bikes on gravel paths. One recent traveler’s tip: fill up with food supplies in Mengen town before heading in, as nothing (not even basic staples) is sold inside the park.
• Adventure Seekers: Though not “extreme,” Yedigöller has adventure for those who seek it. In winter, snowshoeing or cross-country skiing through the snowy fir forest is challenging and rewarding. Spring snowmelt can swell creek crossings. The longest hiking loop (15–18 km) appeals to seasoned trekkers. Fishing aficionados can test their skills under the trout farm’s oversight. Photo-hunting for wildlife (like elusive bear tracks) can be an adventure. The ridge paths to Kapankaya get steep enough to be a good workout. Mountain bikers occasionally challenge themselves by riding the main service road (though cycling is not officially on trails). In all cases, “adventure” here means long days in nature rather than technical feats. For riskier trips (like winter camping), having a local guide or at least good gear is advised.

No matter the traveler profile, a local guest’s common advice is: “Arrive early, stay late.” Dawn and dusk are when wildlife stirs and the light is perfect, but many day visitors come midday. So plan to start hikes at sunrise if possible, and leave a little after sunset. Also, book your accommodation as far ahead as possible to avoid disappointment (especially as a couple wanting a special room, or a family needing multiple beds).

Beyond the Seven Lakes: Nearby Attractions

If you find yourself with extra time in Bolu province, there are a few nearby natural and cultural sights worth mentioning:

• Abant Lake (Abant Gölü Milli Parkı) – About 40 km southwest of Yedigöller, Abant is a larger lake park also famed for its forest and a panoramic road. It has better developed facilities (horse rides, horseback trails, a big hotel) but is often more crowded. Many travelers combine the two parks for a multi-day trip.
• Gölcük Nature Park – On the western side of Bolu city, Gölcük is a small alpine lake with a circular boardwalk. It’s a quick detour on the way to Yedigöller from Bolu. This is very touristy and less wild, but worth a photo stop.
• Safranbolu – A bit farther (90 km north), the historic Ottoman town of Safranbolu is a UNESCO site known for its preserved wooden houses and bazaars. It’s a cultural contrast and often paired with Bolu trips.
• Kartalkaya Ski Resort – Just 60 km south of Yedigöller lies Bolu’s ski country. In winter, many skiers will take a day off slopes to snowshoe at Yedigöller (as carded in some tour packages).
• Mengen Town – 20 km south, Mengen is known as Turkey’s “town of chefs.” It has a famous culinary festival and several chef-run restaurants. It’s an interesting lunch stop on the way in/out.
• Kapankaya (if not counted) – Technically part of the park, some references separate this viewpoint as a specific attraction.

Mentioning these nearby sites can be helpful for travelers planning a longer itinerary in the region.

A Sample 3-Day Yedigöller Itinerary

To put it all together, here is a sample itinerary for a 3-day trip, which hits all the highlights:

• Day 1: Arrival and Lakes
  • Morning: Drive or bus into Yedigöller. If arriving early, first explore İncegöl and Sazlıgöl (the entrance lakes) – these can be seen right from the parking area. Take some photos at the little reed-fringed Sazlıgöl.
  • Midday: Walk or drive to Büyük Göl. Eat lunch (packed picnic or at Habitat Restaurant by the lake). After lunch, take the easy loop trail north: visit Seringöl and Deringöl (a few kilometers hike). Sit by the wooden boardwalk at Deringöl for quiet reflection.
  • Afternoon/Evening: Set up camp at Büyük Göl (if camping) or check into a nearby bungalow. Relax with tea and enjoy the forest ambience. For sunset photography, head to Nazlıgöl waterfall – it’s a short walk from Büyükgöl’s parking. Relax at the campground in the evening, maybe light a fire in the barrels after dark.
• Day 2: Hiking and Viewpoints
  • Early Morning: Hike up to Kapankaya viewpoint. Leave campground at dawn (before 7 AM in summer; 8–9 in fall). Reach the tower for sunrise (carry flashlight). Enjoy the sunrise panorama over the lakes. Return to camp by mid-morning.
  • Late Morning: Breakfast and rest. Visit the Pisagor Tree near Büyük Göl (a 90-degree beech; 10-minute walk from restaurant).
  • Afternoon: Do the hike through Nazlıgöl. Walk the trail that encircles Nazlı and Deringöl fully. In autumn, this trail is flanked by color. If energetic, continue to loop around Büyükgöl (completing the main lake loop if not done fully Day 1).
  • Evening: Another dinner at the campsite or restaurant. If ambitious, try a short night hike (just for star photos) to a dark spot by Deringöl.
• Day 3: Optional Activities and Departure
  • Morning: Leisurely morning. If staying for breakfast, enjoy a sunrise visit to Seringöl for calm waters. Else, pack up and hike the short trail to İncegöl (walk behind the park sign).
  • Late Morning: On way out, stop at Kapankaya again for a quick look, or do any missed short hikes (e.g., woodland paths north of İncegöl).
  • Early Afternoon: Depart park. If time allows, eat in Mengen town on the way back for a taste of local cuisine.

This is just one plan. If you had only 1 day, concentrate on Büyükgöl–Nazlıgöl–Kapankaya. For 5 days, you could add trips to Abant Lake and Mengen villages.

Responsible Tourism in Yedigöller: Preserving Paradise

Above all, Yedigöller exists because it has been protected from overuse. We must each do our part to keep it that way. Responsible practices here include:

• Pack It In, Pack It Out: Take all your trash. This park is known for silence – leaving litter would break that serenity and endanger wildlife.
• Stay on Trails: Avoid creating new paths through vegetation. Use established trails and respect any roped-off areas.
• No Feeding Wildlife: Even bread to ducks can be harmful. Wildlife survive on natural diet; feeding encourages dependency and can alter animal behavior (and is often illegal).
• Minimize Campfires: Use only designated fire bins. If you cook, use a stove or contained grill. Never leave a fire unattended. The woodland soil holds dry fuel; one spark could cause a forest fire.
• Conserve Water: It’s safe to drink, but do not wash clothes or dishes in streams or sinks. Use biodegradable soap at least 50 m from water sources.
• Respect Cultural Rules: For example, the park has a mosque/ablution for visitors. This is a place of respect; shoes off and modest dress if entering.
• Support Local Economy: If eating or buying anything, prefer local restaurants and shops (Mengen inns, park cafe). This encourages communities to value the park.

By treating Yedigöller gently, visitors help ensure it remains the “silence paradise” it is. Park signs often quote the law that violators may be fined and banned. In practice, honor system and peer pressure help keep others honest. Many Turks visiting display a deep affection for the place; visiting with that same respect fits the spirit.

Frequently Asked Questions (FAQ) about Yedigöller National Park

Q: Is Yedigöller worth visiting? Yes. For nature lovers and photographers, Yedigöller’s lakes and forests are exceptionally scenic. Autumn is especially stunning. Just know it’s rustic – no luxury hotels or rides. Families, couples and hikers all find something here, if prepared.

Q: How do I get to Yedigöller from Istanbul or Ankara? Drive or take bus to Bolu, then follow the signs via Yeniçağa–Mengen to the park. Alternatively, take a bus to Bolu then a shuttle (weekend only) or local mini-buses toward Yazıcık. See details in “How to Get There” above. A car hire is easiest; public transit requires multiple transfers.

Q: When is the best time to visit Yedigöller? The “best” season depends on interest: autumn (mid-Sept–Oct) for foliage, spring (Apr–May) for wildflowers, summer if you want warmth and full greenery, and winter if you enjoy snow. Generally, fall (Sept–Oct) is most celebrated for beauty.

Q: Are there entrance fees? Yes. As of 2025, it’s 60 TL per adult (student 30 TL) for pedestrians, and 180 TL per car (flat rate with unlimited people). Buses and motorbikes have their own fee. Camping is included. (Keep TL cash.)

Q: Can you camp in Yedigöller? Yes, only in the official campground by Büyük Göl (and a few small spots). Camping is free with the entrance fee. Facilities are basic: toilets and water taps only. No fires except in provided fire rings. Advance reservation for campsites is strongly recommended for holidays or weekends (many are first-come, but popular slots fill quickly).

Q: What should I bring for camping? A sturdy tent, sleeping bag and pad, warm layers (even in summer nights get cold). Headlamp, portable stove, insect repellent, and all food/water. Tarps for wet weather. Remember no firewood gathering – bring your own fuel if needed.

Q: What can you do in Yedigöller besides hiking? Aside from hiking and camping, key activities are photography (scenery and wildlife) and fishing (with permit). Birdwatching and nature study are rewarding. There are no zip-lines or rentals; recreation is low-impact. In winter, snowshoeing and stargazing are popular.

Q: Are there bears in Yedigöller? Yes, brown bears live in Bolu’s forests and sometimes range into the park. However, encounters are rare. Still, always store food securely when camping, and make noise on trails in winter to avoid surprising any. Seeing a bear is highly unlikely for a casual visitor.

Q: Is the road to Yedigöller dangerous? The final road from Yazıcık/Mengen up to the park is narrow and winding. In good weather it’s okay for a careful driver, but in fog or rain it can be risky. In winter it may require snow chains. Drive slowly, watch for blind curves, and don’t attempt after dark if possible. (Some guides note it is “quite bad” in places.)

Q: Can you swim in Yedigöller’s lakes? No, swimming in the park lakes is forbidden for safety (unknown depths, cold water) and ecological reasons. Signs (and local guides) explicitly warn that swimming is prohibited (one caption warns “it is dangerous and forbidden to swim in the lake”). Instead, enjoy the view or fish. There are no lifeguards.

Q: Are there hotels inside Yedigöller? No. Accommodation within the park is limited to campgrounds and bungalows (no 5-star hotels or large inns). The Habitat bungalows and group lodges are the closest to “hotel” comfort. For a true hotel stay, the nearest town is Bolu (42 km away) which has many mid-range and budget hotels.

Q: Is there a restaurant or cafe in Yedigöller? Yes. The main eatery is the Habitat Restaurant by Büyük Göl, serving Turkish food (notably fresh trout). A smaller Sincap Cafe offers snacks, gözleme and homemade desserts. Both are open daily, but hours may be limited in off-season. Outside food options are just outside in Mengen or Bolu towns.

Q: What wildlife can I see? Deer and boars are common. You may spot foxes, badgers, or squirrels. Birdlife is rich (woodpeckers, tits, warblers). Rare mammals like lynx or bears occur but sightings are very rare. Cameras and patience help.

Q: Do I need a guide to hike? No, the trails are straightforward enough for a self-guided trek if you are prepared. A local map and compass/GPS are wise. Signs exist but are not abundant. Guides are optional if you want detailed nature info. During major autumn weekends, the park can get crowded, and some visitors have organized folk dances or events; but these are casual, not formal tours.

Q: Is there cell phone reception in the park? Coverage is spotty. You might get signal near İncegöl parking or atop Kapankaya, but deep in the woods service can drop. Do not rely on your phone for navigation or emergencies unless you have backup (power bank, offline maps).

Q: What about food and water? Bring snacks and plenty of drinking water (there are potable water taps, but it’s good to carry your own). For meals, the park’s restaurant/cafe is open daytime, but close after dinner. If you arrive late or leave early, have provisions for breakfast. Outside the park, Mengen and Bolu have supermarkets to stock up before entering.

Q: Can I recharge devices or pay by credit card? Electricity is only available at the cabins or restaurant (not guaranteed everywhere). There are no public charging stations for phones. Credit cards may be accepted in the restaurant; otherwise carry cash for small purchases (even the entrance fee is typically cash-only).
