Altındere Valley National Park in northeastern Turkey’s Black Sea region is a landscape of rugged beauty and deep history. Straddling a steep, wooded gorge just west of Trabzon city, the park is best known for the cliff-hanging Sumela Monastery – but its allure extends far beyond this famed site. Lush forests of fir, spruce and beech cloak the valley’s high walls, a splinter of wild Pontic nature where chattering streams and hidden waterfalls carve the rock. Endemic flowers carpet the forest floor in spring, and birds from eagles to woodpeckers trace the air. All the while, a winding road brings visitors into this hidden valley of cultural wonders and untamed scenery.
From the narrow parking lot at 950 m altitude, a 1-km footpath climbs through dense foliage to reach the Sumela Monastery at about 1,200 m. On approach one notices the cool mist of the Altındere stream (the Değirmendere) far below, and the lofty silhouettes of ancient church towers ahead. The monastery’s dramatic perch on a sheer cliff is an iconic sight: built into a vertical rock face, it seems almost impossibly constructed. Arriving here after a gentle hike through green, mossy woods – the air heavy with pine scent – visitors often feel as if they have stepped into a timeless sanctuary.
Altındere Valley’s varied appeal makes it a “must-visit” for a range of travelers. History and architecture buffs will linger over Sumela’s story and frescoes; nature lovers will revel in the rich forest, waterfalls and wildlife. Photographers will find endless compositions in the misty monasteries, river gorges and mountain panoramas. Families can enjoy a day on well-marked trails and picnic by the stream. In short, Altındere Valley National Park offers a singular blend of cultural heritage and rugged Black Sea nature – one reason it stands out among Turkey’s protected places.
Despite its small size (around 4,468 hectares), Altındere Valley National Park is widely regarded as one of the Black Sea region’s most important protected areas. Declared a national park in 1987, it safeguards a rich natural ecosystem along with layers of history. The valley’s steep limestone walls – products of the region’s dramatic geologic past – form a narrow corridor choked with dense forests of Eastern spruce, fir, beech and chestnut. In spring and early summer these woods burst into green, and torrents of snowmelt feed small waterfalls and streams that thread the valley. Birdsong and the rustle of animals are constant companions. In fact, official sources note that the park’s flora is exceptionally rich: towering spruce dominates much of the canopy, punctuated by firs, pines, oaks and maples, along with undergrowth of lime and willow. This varied vegetation in turn supports abundant wildlife: deer, wild goats, boar and even bears and wolves range here, alongside smaller carnivores like jackals, foxes and lynx. Birders prize sightings of hawks, owls and woodpeckers among Altındere’s tree trunks.
Embedded in this wild setting is Sumela Monastery, Altındere’s cultural heart and Turkey’s premier cliff-cave church. Founded in the late 4th century AD, Sumela was built as a dedication to the Virgin Mary and became a major center of Christian pilgrimage. Its name (from Greek Soumela, “Black Virgin”) refers to the dark icon of the Theotokos that was enshrined there. Over centuries the monastery expanded: wooden chapels gave way to stone halls, an aqueduct was built to bring water, and frescoed churches were carved into the rock. When viewed from below or above, Sumela’s cluster of red-roofed buildings and slender bell tower clinging to the grey cliff face is breathtaking – a photographer’s dream and a source of wonder for visitors.
Yet Sumela is only one part of the park’s story. Altındere offers something for everyone. Hikers can wander trails that loop through deep woods and across rivers. Botany fans can catalog dozens of Black Sea species – from endemic wildflowers to towering hornbeams. Even a brief visit rewards with a sense of contrast and connection: between the sun-dappled forest floor and the holy, centuries-old chapels on the cliff; between the sound of swift water and the silence of hallowed halls. In short, Altındere Valley is both an escape into nature and a journey into history – a combination that few places match.
Nestled nearly 300 meters above the valley floor, Sumela Monastery (the “Monastery of the Virgin Mary”) is the spiritual and architectural heart of Altındere National Park. For history buffs and pilgrims alike, it stands as a miracle of faith and engineering, carved directly into the cliff. In folklore and fact, Sumela’s origins reach back to late antiquity. Christian tradition holds that two Athenian monks – Barnabas and Sophronios – founded the monastery around AD 386 during the reign of Emperor Theodosius I. These monks were reportedly guided by a holy icon of the Virgin Mary (said to have been painted by St. Luke himself) that miraculously appeared at a mountain spring. Following that “sign from God,” they built a small rock church and cells into the crag by the stream, thus beginning what would become Sumela.
Over the next millennium, Sumela grew in stature and size. Byzantine generals (like Belisarius) and Pontic emperors contributed to its expansion. The monastery took on its familiar form during the 14th century under Alexios III of Trebizond (1349–1390), who believed the Virgin had saved him from a storm. Legend says Alexios then rebuilt Sumela in stone, expanding it far beyond its original wooden cells. Indeed, an imperial decree of 1365 granted the monastery tax-free status and special privileges. In its golden age under the Komnenos dynasty, Sumela hosted an esteemed Greek school (the Phrontisterion of Trapezous) and attracted pilgrims from across the empire.
The Ottoman era brought a unique twist: although conquered along with Trabzon in 1461, Sumela was respected by sultans. Later Ottoman decrees confirmed its rights and tax exemptions. Wallachian voivodes (Christian princes of modern-day Romania) even donated funds to restore and adorn the monastery. Throughout this time Sumela remained a mixed pilgrimage site: not only Orthodox monks and pilgrims but also local Turkish villagers revered the Virgin’s icon. The monastery’s courtyard gifted wine, grain and honey to visitors of all faiths.
Architecture and Layout. Entering Sumela today feels like stepping into a vertical village built on the rock face. A steep, narrow stone staircase leads up through the trees to the monastery entrance. Here, beneath high arches, stand the ruins of a once-grand aqueduct that channeled water up from the valley below. From the entrance level one ascends further via a winding path and stairway that brings you to the various buildings. The Rock Church (or Panagia Church) is the spiritual core: a cave chapel carved out of the cliff, with its roof and walls dating back to 13th-14th centuries. Light filters into the Rock Church’s nave through narrow windows, illuminating faded frescoes that ring the walls. Within this chapel one finds the cultic center – the holy spring whose drips drop into a stone cistern below. According to legend, this spring was the very spot where the icon was discovered; even today believers touch the spring’s flowing water as a blessing.
Adjacent to the Rock Church are numerous auxiliary buildings. A large guesthouse and monks’ quarters, added in the 19th century, stretch above and below the church. These are three-story stone blocks with arched balconies facing the cliff, essentially a stone fortress-inside-the-rock. Weights of time have toppled much of the upper levels, but portions remain. To one side, a library once stored precious manuscripts – a loggia or stone gallery still stands with its carved ledges. On the other side were the kitchens and dining halls: you can see the foundations where large hearths and ovens were built. A thicket of rooms includes former “student rooms” (seminary cells) and a small chapel to St. Michael. Throughout the complex, crowds of stairways, passages and platforms connect these chambers, making Sumela feel like a labyrinthine cliff-citadel.
The cliffside Rock Church at Sumela Monastery – its painted interior walls are the centerpiece of the complex. Visitors must climb steep steps to reach this sacred chamber carved into the rock.
Frescoes and Art. What makes Sumela especially famous is its art. The interior walls of the Rock Church and nearby chapels are covered with frescoes illustrating Biblical scenes and saints. These Byzantine paintings date from several periods. The back wall’s portraits of the Virgin and Child, and scenes of the Nativity, are attributed to Alexios III’s renovation (14th c.). On a side chapel’s walls are more vivid scenes (Annunciation, Crucifixion, and others) painted in the 18th century after extensive Ottoman restorations. The common theme throughout is the life of Christ and the Theotokos: angels, apostles, martyrs, Christ’s miracles, and so on. Unfortunately centuries of weather, earthquakes and vandalism have heavily damaged many frescoes. What remains are often shadows of the originals – red and ochre figures on peeling plaster – but they convey the monastery’s original grandeur. In recent restorations workers even uncovered a hidden tunnel leading to an underground chapel, revealing previously unseen murals of heaven and hell on its walls.
Restoration and Preservation. In the late 20th century, Sumela’s fragility became increasingly clear. After decades of neglect, the monastery was closed entirely in 2015 due to safety concerns: pieces of cliff were falling onto the buildings below. The Turkish government then launched a major restoration and stabilization project. Between 2016 and 2019 engineers installed supports, reinforced rock faces and restored key structures. By May 2019 the first phase allowed limited visits; in 2020 Sumela reopened fully. The work cost tens of millions and illustrates how vulnerable this site is to both nature and tourism. Despite its endurance through empires, Sumela requires constant care – a reminder of the balance between sharing cultural heritage and preserving it.
Is Sumela Monastery Worth Visiting? Absolutely – but with realistic expectations. No other place in Turkey offers such a dramatic combination of history and scenery. The setting alone – a Greek Orthodox monastery hanging on a cliff in a Black Sea forest – is unmatched. Inside, even fragments of fresco and old stone architecture tell stories spanning 1,600 years. For historians and art lovers, Sumela is a rare surviving Orthodox community. For religious visitors, it remains a revered shrine (a liturgy is held each August 15th, the Dormition of Mary). For the casual traveler, the panoramic views from its terraces are spectacular. However, note that the interior halls are in ruins: the buildings are partly collapsed, and frescoes are faded. It’s more of an atmospheric ruin than a pristine cathedral. Still, most visitors agree that the sense of wonder here makes it more than worth the effort. A tourist’s candid assessment might say: “Yes, go in early morning or late afternoon for the best light, plan at least 2–3 hours here, and bring water – the climb is easy but the air is thin.” In sum, Sumela’s value is cultural and photographic, not spiritual in a traditional sense (the site is secular). But almost everyone who visits is amazed.
How Long to Visit Sumela Monastery? Plan on at least 2 to 3 hours. Allow time for the hike up from the parking area (about 15–20 minutes of stairs and path at a gentle incline), then leisurely exploration. The core Rock Church takes a few minutes to admire. To see all accessible sections (guesthouse ruins, chapels, the aqueduct archway, and the panoramic terrace below), count on an hour or more. Some visitors pause at the riverside café near the parking, others combine Sumela with a visit to nearby waterfall trails. In short, it’s not a 30-minute stop – it’s a half-day outing if you want to truly take it in.
Can You Go Inside Sumela Monastery? Yes, most of the complex is open to the public (as of 2025). Visitors can ascend the cliff stairway and walk the stone courtyards. Entrance includes access into the Rock Church interior (cave chapel) where the frescoed walls stand (though no services are held there except the one annual Dormition mass). The newer guesthouse sections and library are mostly roofless ruins, but their doorways and foundations are accessible. However, not every corner is reachable: some inner rooms are blocked off for safety, and the very top terraces are off-limits. Importantly, photography is allowed (without flash indoors). Tours are unguided – there are informational signs in multiple languages. No special permit is needed beyond the entrance ticket. There is a shuttle bus that runs from the lower car park up to the monastery for 27 TL (buses depart every 5–10 minutes), which is recommended for anyone who cannot easily climb stairs. Otherwise, be prepared for a final stretch of uphill stairs on foot – but rest stops with benches are provided along the way.
A successful visit to Altındere requires a bit of planning. From transportation to seasonality to on-site logistics, here is everything you need:
The Black Sea climate makes Altındere lush but unpredictable. Here is a seasonal breakdown:
Entrance Fees (2025): Altındere National Park has an admission fee administered by Turkey’s General Directorate of National Parks. As of 2025 it costs ₺60 for a regular adult and ₺30 for students, seniors and locals. (The museum pass card is not valid for the park entrance fee.) Note: This is the fee to enter the park area. In addition, when approaching by car one must pay a ₺17 parking fee (per vehicle) to enter the park perimeter. The minibus ride up to the monastery is ₺27 per person. Finally, the monastery itself has its own entry ticket (see below).
Sumela Monastery Ticket (2025): In addition to park admission, visitors must buy a ticket for the Sumela Monastery complex. For 2025 the prices are ₺450 for an adult and ₺0 for children under 18 (students and seniors generally free). Turkey’s annual Museum Pass is accepted (covering Sumela) – the adult Museum Pass is ₺60, student pass ₺30, making it the most economical option if you plan multiple sites. (Sumela tickets can be purchased on-site at the monastery’s entrance, or online via Turkey’s national monuments website.)
Opening Hours: Sumela Monastery has different hours by season. In high season (April–October) it is open from 08:00 to 19:00 daily. In winter (November–March) the hours shorten to roughly 08:00–17:00. The park itself is typically open every day of the year, but access to Sumela is best during the above visiting months. Note that heavy rain or natural events can temporarily close the site; always check ahead if you have booked travel.
Facilities: At the park entrance and monastery there are basic amenities. The Visitor Center has restrooms, a ticket office and gift shop selling souvenirs and snacks. A nearby café offers tea, water, light meals and the local trout (hamsi) on weekends (rumored to be fresh-caught from the river below). Look for riverside restaurants about 1 km before the monastery – locals often recommend the trout platter and traditional dishes there. Picnic tables are available in the park’s picnic area near the parking. Hiking signposts mark major trails. Emergency first-aid is on site (there is a rescue post). Stay aware: Cell service can be spotty in the valley, and the network infrastructure is limited. Bring snacks and full water bottles, as options are modest.
Dress for a forest mountain outing. Closed-toe walking shoes or boots are strongly recommended – the trail to Sumela is mostly paved but rocky in places. In summer, lightweight layers are wise: the valley bottoms can feel warm, but shade and spring-fed breezes cool the air. Bring a light jacket for higher viewpoints, and rain gear year-round (the Black Sea climate is famously wet). Spring/fall visitors should have warm sweaters for evenings. Modest attire is expected if you enter the church (e.g. shoulders and knees covered; women can bring a scarf to cover their head during church visits).
Essentials to pack: Water and snacks (only limited purchases possible on-site), sunscreen and insect repellent, and perhaps a picnic lunch. A walking stick can help on the stairs. A camera is obviously warranted. Leave No Trace: carry out any trash or plan to use park bins if provided. A small first-aid kit is handy (though a medical post is nearby).
Altındere Valley’s terrain is rugged, so full access for wheelchairs or strollers is not available. The path from the parking area to the monastery includes uneven stone steps and slopes that are challenging even for able-bodied hikers. Visitors with limited mobility can still enjoy the park: the car park and café areas are level, and there are viewing spots where one can see the monastery from below. The official minibus provides access to a paved area just outside the monastery entrance, but then one must climb more stairs to actually enter the Rock Church. In practice, wheelchairs cannot reach the interior of Sumela Monastery. However, family members or caretakers can accompany and enjoy the entry plazas and nearby paths. If needed, ask the site staff about any temporary assistance (e.g. the park staff occasionally provide short carrier rides up the last leg for seriously disabled visitors).
In recent years a dedicated accessible viewing platform has been added near the park entrance. This observation deck has a ramp and allows panoramic views of the valley and the distant monastery façade on the cliff. It is reachable from the parking lot via a well-graded gravel path. For wheelchair users or those who cannot climb, this platform offers a taste of the scenery without the strenuous hike.
Most visitors to Altındere focus on Sumela, but venturing further into the park rewards with hidden gem trails, wildlife and geology.
Altındere National Park boasts several marked trails, from easy walks to challenging treks:
Trail Safety and Gear: All trails in Altındere are non-technical but can be slippery when wet. Wear good hiking shoes with grip. Do not wander off trails, especially near cliff edges. There are a few signposts, but it’s wise to carry a simple trail map or use a GPX track. Hiking poles can help on rough descents. Inform a ranger or friend of your plans, since some trails cover remote terrain. The park staff advise: stay hydrated, protect against sun and insects, and respect quiet zones for wildlife.
Flora (Plants). The park’s temperate rainforest is spectacularly biodiverse. KTB’s official description notes “towering Eastern spruces, with areas of fir and Scots pine” as dominant species. Indeed, enter the woods and you will see forests of tall black pines and spruces with understories of mountain laurel (Bay Laurel), rhododendron and wild azalea. Mixing in are groves of Oriental beech and sweet chestnut (especially on the east slope), and rare Caucasian firs. In spring, the forest floor blooms with wildflowers: iris, lilies, orchids and Anemone species splash the shade with color. The slopes are also home to unique endemic plants of the Pontic region; botanists have recorded mosses and ferns that cling to the moister rock surfaces. Many of these tree and flower species are shared only with the nearby Kaçkar and Munzur ranges.
Fauna (Animals). The diversity of plants supports a wide array of wildlife. Large mammals include wild boar, red deer and roe deer, as well as mountain goats in higher areas. Predator species recorded here include brown bears, wolves, foxes and jackals – though these tend to avoid human traffic, so sightings are rare. More common is the lynx, a shy forest cat known to prowl Altındere (conservationists welcome its presence as a sign of healthy woods). Smaller creatures abound: stone martens and badgers scurry through the brush, and amphibians like salamanders dwell by the creeks.
The valley is a birder’s paradise. Raptors such as eagles and hawks circle overhead, hunting from the cliffs. Woodpeckers (including Middle and Lesser Spotted) drum on the dead trunks, while warblers and thrushes flit through the understory. Spruce groves echo with the calls of owls and birds of prey. In April and May, migrants pause here on their way north. A visitor survey once noted species like the Caucasian grouse (tavuk-like), sparrowhawk, golden oriole and even the rare bearded vulture in the sky. While the park authorities have not published a full species list, official sources mention “hawks, magpies, woodpeckers, owls, blackbirds” among others. In fact, one common sight is the majestic griffon vulture, which nests on the highest cliffs surrounding Sumela (a natural predator cleanup crew!).
Altındere’s wildlife tends to be timid around humans, but if you rise early or hike quietly, you might catch glimpses of deer or hear the plaintive howls of foxes at dusk. Bird-watchers should bring binoculars and a field guide – the mix of forest and alpine habitats means many possibilities. Remember: feeding animals is illegal; enjoy them from a distance.
Water is Altındere’s lifeblood. The Değirmendere Stream (also called Altındere) winds through the canyon, fed by multiple tributaries tumbling from the slopes. This mountain stream is clear and cold, home to trout and freshwater crustaceans. Several times along the hiking trails one can cross it by wooden bridges or rock fords. In spring, it swells to a roar as snow melts in the high ridges. The original Sumela founders built aqueducts and channels to lift its water up to the monastery; remnants of these stone watercourses still run along cliff ledges.
A handful of small waterfalls lie hidden among the trees. The most accessible is just below the monastery: a 20-meter cascade that crashes into a plunge pool near the picnic area. (You may hear it roaring before you see it.) In summer, hikers often cool off in this pool. Higher up the valley, a steeper trail leads to another cascade known locally as Şaledoner. These falls are seasonal but can be very photogenic, especially after rain. On quieter trails, the gurgling of streams and the trickle of tiny forest springs is constant – one feels immersed in flowing water.
Perhaps most intriguing is the healing spring at Sumela itself. Inside the Rock Church, thirty or forty meters above, water drips in plink-plunk fashion from a ceiling of limestone into a stone basin. Legend claims this water cures ailments, which is why pilgrims long ago built that sacred cistern. Today most visitors touch the dripping water out of reverence. Whatever the truth, the theme of water – from its simple dripping in a cave to the grandeur of a mountain waterfall – is woven into Altındere’s experience.
Altındere’s dramatic cliffs and deep gorge are the result of millions of years of geologic activity. The park lies within the Pontic Mountains, a range formed by the collision of tectonic plates in the Tertiary period. Deep gashes cut northward from the central spine of these mountains were carved by rivers and glacial action. Altındere itself follows a fault line where limestone and marble were uplifted and cracked. Over time, the Değirmendere stream has eroded a nearly vertical canyon nearly 3 kilometers long. The rock here is primarily Cretaceous limestone – hard and stratified – which gave rise to the cliff on which Sumela was built. Small caves and overhangs abound, some of which have been used by wildlife (and by monks centuries ago).
The valley’s structure can be read in its layers: look carefully and you might spot fossils of ancient marine organisms (this entire area was once seabed). The forested sides are studded with boulders and talus from past rockfalls. Indeed, Sumela’s instability in modern times attests to this ongoing geology. Speaking of ongoing processes, landslides and erosion continue to subtly reshape Altındere – a humbling reminder that even these “mountains of millennia” are alive.
While detailed geologic field studies of Altındere are limited (most focus on its botany and archaeology), the park’s Visitor Center has diagrams explaining the layers. It notes, for example, that limestone in Altındere dates back about 90–100 million years. Tensile stresses from regional earthquakes have caused the cliffs to fissure, creating pathways for rainwater that chemically weathers the rock. For travelers, the take-away is that the valley you walk through is a slice of Earth’s history – and one that required nothing less than geological forces to set the stage for the monastery.
Altındere’s remote location means choices are somewhat limited, but you won’t have to sleep in your car.
When you dine out, ask for these by name – most cafes in Trabzon-Maçka will happily prepare them if asked. English may be limited outside major towns, but menus often have pictures. Water, tea and ayran (yogurt drink) are the go-to beverages.
For shutterbugs, Altındere is a goldmine of photo opportunities. Whether you use a phone camera or a full rig, plan shots at different times of day:
For general tips: pack a wide-angle and a telephoto. Low light (inside the Rock Church) can be challenging, so use high ISO or a fast lens if you want detail on frescoes. People add interest: catching a solitary figure on the monastery steps can give scale and story to your shot. Aim to have at least one camera-ready outfit for the group (the contrast of modern clothing against the ancient rock can be striking). And of course, don’t forget a photo with you and Sumela in the background!
Altındere’s status as a national park and UNESCO Tentative site underscores its value. Park management’s goals are to preserve this unique blend of nature and history. That said, Altındere faces challenges:
Altındere’s region is rich enough to fill several days. Here are some not-to-miss nearby sites:
