Yedig\u00f6ller National Park (Turkey\u2019s \u201cSeven Lakes\u201d park) is a remote and tranquil treasure in the Bolu Province.<\/p>\n
Yedig\u00f6ller (Seven Lakes) stands out among Turkey\u2019s nature parks for its quiet beauty, especially in autumn. In a sentence: Yes<\/strong>, it is generally considered worth a visit for nature lovers and outdoor photographers. The park\u2019s core attractions are its seven mountain lakes<\/strong> and intact forest. These glacial (landslide-formed) lakes \u2013 named B\u00fcy\u00fck G\u00f6l, Nazl\u0131g\u00f6l, Sazl\u0131g\u00f6l, \u0130nceg\u00f6l, K\u00fc\u00e7\u00fckg\u00f6l, Sering\u00f6l and Dering\u00f6l \u2013 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<\/strong>, when reds, oranges and yellows blaze around the lakes. Even outside fall, visitors report a profound stillness and lush greenery: \u201cOne can always enjoy the silence of nature and feel absolute serenity here\u201d. 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.<\/p>\n On the other hand, Yedig\u00f6ller is quite rural and rustic<\/strong>. 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, Yedig\u00f6ller 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<\/strong>, with dozens of local guides and blogs declaring fall (late September to October) \u201cmagical\u201d<\/em>. 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).<\/p>\n Yedig\u00f6ller will likely delight anyone seeking unspoiled lakes, forests and low crowds<\/strong>. It may not<\/strong> thrill those who want city-like comforts. In the sections that follow, this guide will cover everything<\/em> 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<\/strong>, with data and tips far beyond what existing blogs or brochures provide.<\/p>\n Yedig\u00f6ller\u2019s very identity rests on its seven mountain lakes<\/strong>, 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: Sazl\u0131g\u00f6l<\/strong>, \u0130nceg\u00f6l<\/strong>, Nazl\u0131g\u00f6l<\/strong>, B\u00fcy\u00fckg\u00f6l<\/strong>, K\u00fc\u00e7\u00fckg\u00f6l<\/strong>, Sering\u00f6l<\/strong>, and Dering\u00f6l<\/strong>. A small eighth pond, Kurug\u00f6l<\/strong> (\u201cDry Lake\u201d), often dries up and is less notable, so it is usually omitted from lists. The Turkish names, translated, hint at each lake\u2019s nature: B\u00fcy\u00fckg\u00f6l = Big Lake, K\u00fc\u00e7\u00fckg\u00f6l = Small Lake, \u0130nceg\u00f6l = Slender or Long Lake, Nazl\u0131g\u00f6l = Coy Lake, Sazl\u0131g\u00f6l = Reedy Lake, Dering\u00f6l = Deep Lake, and Sering\u00f6l = Cool Lake (or simply a name). The largest lake by area is B\u00fcy\u00fck G\u00f6l, and the deepest is Dering\u00f6l. They range from mirror-like ponds in shaded forest to open-water pools flanked by hills.<\/p>\n Below we describe each lake\u2019s key traits. Together they form a wild mirror-scene, with sunrise and sunset light turning their still surfaces to gold or crimson.<\/p>\n Combined, these lakes stretch over roughly 1.5 kilometers<\/strong> north\u2013south and span two terrace levels about 100 meters apart in elevation. The entire \u201cSeven Lakes\u201d sequence rises through a forest valley. The southernmost lake on the upper platform is B\u00fcy\u00fckg\u00f6l; the northernmost (except Kurug\u00f6l) is Dering\u00f6l. 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, Nazl\u0131g\u00f6l<\/strong> drains into Dering\u00f6l<\/strong>, whose outflow goes to B\u00fcy\u00fckg\u00f6l; separately, Sering\u00f6l<\/strong> and \u0130nceg\u00f6l<\/strong> drain toward the Sazl\u0131g\u00f6l side.<\/p>\n Across all seasons, the lakes provide the visual centerpiece of the park. In spring<\/strong>, you\u2019ll see the water level full and lakes edged with fresh green. By summer<\/strong>, tree cover is dense and the lakes glint in light openings. In autumn<\/strong>, each lake turns into a tableau of oranges and reds \u2013 for instance, reflections of golden birches in Sazl\u0131g\u00f6l, or of crimson beeches above Nazl\u0131g\u00f6l. In winter<\/strong>, 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\u2019s edge) means you can usually find a quiet spot for your camera or picnic. As one local travel source notes, the lakes are \u201ccharming simply because they are undeveloped and are never crowded with cars, buses or people\u201d.<\/p>\n Therefore, the \u201cSeven Lakes\u201d are not just a list of names \u2013 each one has its own character and best viewpoint. In planning your visit, you might start with the lower lakes<\/strong> (\u0130nceg\u00f6l, Sazl\u0131g\u00f6l) right at the entrance, then hike or drive northward to B\u00fcy\u00fckg\u00f6l 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 Dering\u00f6l). 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.<\/p>\n Yedig\u00f6ller\u2019s 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\u2019s climate is shifting, but averages are as follows for Bolu\u2019s region (the park sits roughly at 900 m altitude):<\/p>\n Best time summary:<\/strong> For most visitors, mid-September through October<\/strong> is ideal for the full autumn spectacle. If you prefer fewer crowds or want wildflowers, consider May<\/strong>. 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\u00b0C at night, and even in fall\/winter a sudden rain or snowfall can occur.<\/p>\n Once at Yedig\u00f6ller, 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 \u2013 the \u201cactivities\u201d are basically outdoor pursuits<\/strong> 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.<\/p>\n Yedig\u00f6ller has no paved roads through the forest (aside from the main car approach). Instead, there are marked foot-trails<\/strong> linking the lakes and ascending nearby hills. Trails range from an easy paved loop around B\u00fcy\u00fckg\u00f6l 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:<\/p>\n (Other trails)<\/em>: 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 Sazl\u0131g\u00f6l shore, where wildflowers bloom in spring. Another is to follow the stream from Nazl\u0131g\u00f6l downstream to Dering\u00f6l, 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:<\/strong> The main trailhead for all hikes is the parking area by \u0130nceg\u00f6l (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\u2019s wildflowers (primroses, anemones, cardamines) also make any hike memorable.<\/p>\n Yedig\u00f6ller is a photographer\u2019s paradise<\/strong>, especially for nature and landscape photography. Each lake and season offers unique compositions. Here are some tips and highlights:<\/p>\n 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.<\/p>\n Camping is a very popular activity in Yedig\u00f6ller National Park. Authorities designate specific areas for camping, primarily around the shores of B\u00fcy\u00fck G\u00f6l and Dering\u00f6l. Important:<\/strong> In-forest or \u201cwild\u201d camping anywhere off these sites is illegal<\/strong>. The official campground at B\u00fcy\u00fck G\u00f6l 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<\/strong>. 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\u2019s rustic campground.)<\/p>\n A highlight of the park\u2019s official information is that campfire is prohibited except in provided steel bins<\/em>: \u201cAll fires (including samovars) are banned, except that campers may burn wood in barrels after dark\u201d. 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.<\/p>\n The park offers rental of full-service \u201cnature houses\u201d (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<\/em> and foggy \u2013 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).<\/p>\n Camping Etiquette:<\/strong> Pack in all your supplies and pack out all<\/em> garbage. Do not cut or damage any trees for wood (use only dead sticks if anything). Keep voices low at night. The park\u2019s famous silence is part of its appeal, so late-night partying is inappropriate. The campground closes at an implicit gate at night, so don\u2019t plan to hike back in darkness.<\/p>\n Finally, note that winter camping (Dec\u2013Feb) is for the truly hardy. Temperatures can be well below freezing at night, and snow can cover the ground. The campground\u2019s 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.<\/p>\n Even if you\u2019re not overnighting, Yedig\u00f6ller is designed for day visitors who want to picnic and relax<\/strong> in nature. At the main camp area by B\u00fcy\u00fck G\u00f6l there are picnic tables under trees and a small caf\u00e9 (\u201cSincap Cafe\u201d). Farther in, Dering\u00f6l has a few benches. Given the intact forest, nearly any shaded spot on a lakeshore is a perfect picnic location. Some recommended times\/places:<\/p>\n There are no vending machines or shops inside the park beyond a few snack stands (Habitat Restoran and Sincap Caf\u00e9 serve food, below). Therefore, bringing your own food and water is essential<\/strong> for serious picnickers. Many visitors bring coolers with sandwiches, fruit, and ample drinking water (tap water is potable). July\u2013September 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).<\/p>\n 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.<\/p>\n Yedig\u00f6ller\u2019s 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<\/strong> 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\u2014foxes, jackals, wildcats or even lynx\u2014do roam but are rarely seen by casual visitors. Brown bears are present in Bolu forests (the European population), but encounters in Yedig\u00f6ller itself are extremely unlikely unless you go deep off-trail. (Safety note:<\/strong> Do not leave food scraps; bears and boars may come if any smells are left out.)<\/p>\n For wildlife photography or bird-watching, bring binoculars or a telephoto lens. Some specific tips:<\/p>\n Park authorities prohibit feeding or approaching wildlife. Enjoy the animals from a distance. The in-park caf\u00e9 and campground sometimes have signs reminding visitors that deer and bear roam, encouraging caution.<\/p>\n Yedig\u00f6ller has a longstanding trout-farming tradition: in fact, Turkey\u2019s first trout farm (1969) was established here. The lakes and streams hold trout (locally called \u201calabal\u0131k\u201d) which anglers prize. Recreational fishing is allowed<\/strong>, 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 B\u00fcy\u00fckg\u00f6l and Nazl\u0131g\u00f6l have banks open to anglers). Seasonal restrictions apply during trout-spawning months (rainy winter\/spring). Local information in Turkish notes that the Angler\u2019s License can be obtained from the [Nature Conservation branch office], and you must carry it while fishing.<\/p>\n As of writing, the park\u2019s official visitors\u2019 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.<\/p>\n Overall, fishing in Yedig\u00f6ller is a quiet, solitary pastime \u2013 if you\u2019re careful to follow the permit rules. For most foreign visitors, the novelty is trying the local trout; you\u2019ll find \u201calabal\u0131k\u201d on menus at park restaurants as well (see next section).<\/p>\n Yedig\u00f6ller National Park lies in the forested mountains of Bolu Province in Turkey\u2019s Black Sea region. The nearest major cities are Bolu (42 km south) and D\u00fczce to the west. There are multiple travel options:<\/p>\n Public transport to this remote park is limited. In practice, it requires multiple connections:<\/p>\n 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\u2013300 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.<\/p>\n Summary of Getting There:<\/strong> In most cases, visitors drive themselves via Yenica\u011fa\u2013Mengen. Public transport is possible but requires transfers. Once you reach the park entrance (Merkez, Yedig\u00f6ller), you\u2019ll find a small visitor center and parking. The park parking is 100\u2013200 meters before the first lake (\u0130nceg\u00f6l). Remember to pay the entrance fee for your vehicle (10 TL car, or relevant group fee, as below).<\/p>\n There are no conventional hotels inside<\/em> the national park. Instead, lodging options include camping<\/strong>, bungalow cabins<\/strong>, and a few small guesthouses just outside. This section details each category and current pricing estimates.<\/p>\n As noted, camping is permitted only in designated areas, primarily near B\u00fcy\u00fck G\u00f6l. In addition, there are small campgrounds at Dering\u00f6l and possibly near some of the other lakes, but these have no services. The primary campground by B\u00fcy\u00fck G\u00f6l<\/strong> is owned by the park management. It has several dozen marked tent sites and some open areas where RVs can park. Facilities:<\/strong> 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\u2019s 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.<\/p>\n According to the official 2025 fee schedule, camping by tent or caravan is covered by the general entrance fee<\/em>: there is no extra charge<\/strong> 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 \u201c\u00c7ad\u0131r ve karavan kamp\u0131 \u2013 B\u00fcy\u00fck G\u00f6l location free; 2025 giri\u015f \u00fccretleri kamp\u0131 kapsar\u201d.)<\/p>\n Wild Camping:<\/strong> Turkish law and park rules strictly forbid unregulated camping. Some adventurous hikers might consider discreetly camping by Sazl\u0131g\u00f6l or \u0130nceg\u00f6l, but it is against park regulations<\/em>. Rangers do patrol and can impose fines or even close the park for violators. Always camp at the marked site.<\/p>\nThe Seven Lakes of Yedig\u00f6ller: A Visual and Descriptive Journey<\/h2>\n
