The Floodplain Forests of Igneada: the Longoz Forest and the Kyrklareli Lakes

The Igneada Floodplain Forests—a flooded forest near the Black Sea on the border with Bulgaria

When, after a downpour, the water rises in the streams flowing down from the Strandzha Mountains, something happens in the lower groves between the lakes and dunes that you will hardly see anywhere else in Turkey: ash and alder trees literally stand knee-deep in the mirror-like water, and a person with a camera walks here as if through a flooded painting. This is the Igneada Floodplain Forests—a 3,155-hectare national park at the country’s northwesternmost tip, in the Kırklareli province of the Marmara region, near the Turkish-Bulgarian border. The park was established on November 13, 2007, and became Turkey’s 39th national park, uniting several previously separate natural areas. The Igneada floodplain forests are an ecosystem extremely rare for the Mediterranean basin, where marshes, dunes, lagoons, the Black Sea coast, and flooded riparian forests converge in a single location.

History and Origin of the Igneada Floodplain Forests

The geography of this area has been shaped over millennia. For centuries, streams have flowed from the foothills of the Strandzha mountain range (Yıldız Dağları in Turkish—the Star Mountains) down to the Black Sea coast, carrying humus and silt with them every year during the flood season. Thus, a wide floodplain emerged right at the shore, where alluvial terraces transformed into a rare type of forest that the Turks call longoz—a forest that periodically submerges under water. It was from these seasonal floods that what is now shown to tourists as one of Europe’s last relict floodplain forests grew.

The human history of the place is no less intriguing. Local residents trace the very name İğneada (İneada) back to the legendary İne Bey—an Ottoman bey who annexed these lands to the Turkish domain. According to legend, the settlement that grew up near his camp bore the name “İne,” which over time evolved into the current “İğneada.” This eponym has survived to this day and greets travelers on road signs long before they enter the village.

For a long time, these forests remained a half-forgotten corner of Eastern Thrace: there were neither large ancient cities nor medieval fortresses here to attract tourists, as found in other regions of Turkey. Instead, there was silence, fish, and firewood—which was enough for the small villages of Demirköy, Begendik, and İğneada itself. By the end of the 20th century, scientists had noted that the floodplain forests around the Çavuşdere stream were one of the last remaining areas where flora and fauna that had disappeared from the rest of Southeast Europe were still preserved.

On November 13, 2007, the areas with various protection statuses were merged into a single national park. From that moment on, the Directorate of Nature Conservation and National Parks (Doğa Koruma ve Milli Parklar Genel Müdürlüğü) under the Ministry of Environment and Forestry took over management of the territory, built a network of wooden boardwalks and observation decks, and turned the Igneada Floodplain Forests into one of Turkey’s lesser-known yet most atmospheric natural destinations.

The village of İğneada itself is located in the Demirköy district and, prior to the park’s designation, relied on modest summer tourism and fishing in the Black Sea. After 2007, a new role was added—that of an entry point to the national park: guesthouses opened, birdwatching guides appeared, and a small environmental education center began operating. However, a mass influx of tourists never materialized, and many trails remain deserted even on weekends.

Architecture and What to See

There is no “architecture” here in the usual sense—no facades, colonnades, or mosques. Instead, there is the architecture of nature: five lakes of varying nature and character, a ten-kilometer-long ribbon of dunes, the longoz forests themselves, and a narrow strip of Black Sea beach. The route through the park is usually designed as a loop or a chain of points that are easy to reach by car, each with a short 20–40-minute walk.

Lake Erikli is a lagoon cut off from the sea in summer

Erikli (Erikli Gölü) covers 43 hectares and is located north of the village. It is a lagoon: in winter and spring, it connects to the sea via a narrow channel, and in summer, when evaporation exceeds the inflow of water, it separates from the Black Sea and becomes an almost separate body of water. The shores are reed-lined, the water is clear, and at sunset, herons and waders flock here.

Lake Mert is the park’s main body of water

Lake Mert (Mert Gölü), covering an area of 266 hectares, is the park’s largest and most famous lake. It is formed at the mouth of the Çavuşdere stream and surrounded by a true floodplain forest of common ash, alder, oak, and beech. A wooden boardwalk with viewing platforms runs along the shore—it is from here that the most iconic postcard shots of Igneada are taken, where tree trunks are reflected in the mirror-like water.

Lake Saka and the Small Lakes—Hammam and Pedina

In the south of the park, between the longoz forest and the dunes, lies the small Lake Saka (Saka Gölü, just 5 hectares). It is separated from the sea by only a narrow strip of sand and often appears on lists of “Thrace’s quietest lakes.” A little further inland, one or two kilometers from the shore, lie two more small bodies of water: Hamam (Hamam Gölü, 19 ha) and Pedina (Pedina Gölü, 10 ha). These lakes are less accessible and therefore appealing to those seeking solitude and hoping to spot an otter or a black stork.

Dunes and Longoz Forest

A ten-kilometer-long strip of dunes divides the park into two natural zones. To the north, they stretch from Erikli to the village of Igneada itself; to the south, from the outlet of Lake Merta to the sea and the outskirts of Saka, in some places growing up to 50–60 meters wide. Endemic plant species, characteristic only of the southwestern Black Sea region, grow on the dunes; they are protected by an international agreement. And just a few hundred meters from the beach lies a floodplain forest: those very ash, oak, alder, and beech trees, entwined with vines and ivy, which literally stand in water at the height of the flood season.

The Black Sea Coast

Beyond the dunes lies a deserted beach with dark sand and pebbles, almost entirely undeveloped. You can swim during the warmer months, but the currents here are strong, so you should swim with caution. However, the shore is ideal for walks and photography: waves, wet logs washed ashore by the storm, and in the distance—the Bulgarian border and the silhouette of the forested Strandzha hills.

The flora and fauna are what make the trip worthwhile

The forests are dominated by common ash (Fraxinus excelsior), oak (Quercus), alder (Alnus), beech (Fagaceae), and maple (Aceraceae); a distinctive feature remains the climbing plants—vines, ivy, and wild grapes—that entwine the trunks and create that “jungle” effect for which photographers travel to Igneada. The avifauna includes the white-tailed eagle, green woodpecker, gray heron, black stork, hoopoe, cuckoo, kingfisher, and owls. Among the mammals are the wildcat, wild boar, brown hare, pine marten, badger, Eurasian wolf, red deer, fox, and otter. In freshwater, trout, smelt, and mullet are caught, while in winter and summer, anchovies, horse mackerel, whiting, and flounder arrive from the Black Sea. Reptiles found here include the Balkan tortoise, Karelin’s newt, the asp viper, and the common grass snake.

Interesting Facts and Legends

  • Local legends link the name İğneada to the Ottoman bey İne Bey, who annexed these lands to the Turkish domain; the name “İne” eventually evolved into “İğneada”—a rare instance where a Turkish place name preserves the memory of a specific person.
  • The floodplain forests of İğneada are one of the last remaining examples of flooded broadleaf forests in Europe; in most European countries, such ecosystems disappeared as early as the 19th–20th centuries under the pressure of land reclamation.
  • Among the park’s inhabitants are the white-tailed eagle (Haliaeetus albicilla), the black stork (Ciconia nigra), and the Eurasian otter (Lutra lutra)—three species that ornithologists consider indicators of a fully healthy freshwater ecosystem.
  • In 2007, the Igneada Floodplain Forests became Turkey’s 39th national park—the status was granted to several adjacent protected areas combined into a single entity.
  • Every summer, Lake Erikli “closes off” from the sea: the water level drops, a sandbar closes the entrance, and the lagoon turns into a separate lake until the autumn rains—local fishermen have adjusted their fishing calendar to this phenomenon for centuries.

How to get there

Igneada lies in the far northwestern corner of Turkey, in the Demirköy district of Kırklareli Province, near the border with Bulgaria. It is about 250 km from Istanbul and takes roughly three hours to reach. The most convenient option is by car: take the O-3 highway through Saray and Vize, then through Poyralı, Demirköy, and on to Igneada. From Edirne, the drive takes about two hours.

Without a car, you can take a bus from the Istanbul Bus Terminal (Otogar) to Kirklareli or directly to Demirköy, and from there, a local dolmuş to the village of Igneada. The route passes through Silivri, Çorlu, Lüleburgaz, and Pınarhisar. The journey is long (4–5 hours with transfers), and a car is still recommended for exploring the park on your own: points of interest within the park are spaced 5–10 kilometers apart, and there is no public transportation between the lakes.

An alternative is to join a weekend excursion from Istanbul: such tours are regularly organized by environmental clubs and tour operators during the high season. Admission to the park is free, but a nominal fee is charged for parking at some viewing platforms. If you’re traveling from Edirne (which is convenient if you’re combining your trip with a visit to Sinan’s mosques), the route goes through Kırklareli and Demirköy and takes about two hours in total; the road is scenic, passing through the forested foothills of the Strandzha Mountains.

Tips for travelers

The best time to visit is late spring (April–May) and early fall (September–October). In spring, the floodplain forest is partially submerged, the foliage is fresh, and the water level in the lakes is high—this is what creates the famous “mirror-like” shots. In the fall, the forest turns shades of copper and gold, and the weekend crowds have left. Summers here are hot and humid, and the biggest nuisance is mosquitoes: you can’t get by without repellent in the marshy areas.

Practical tips: bring waterproof shoes, especially in the off-season—the wooden walkways sometimes go right into the water; midge and mosquito repellent; binoculars for birdwatching; drinking water and snacks, because there are almost no cafes inside the park (a few simple establishments operate only in the village of Igneada). Swimming in the lakes is prohibited, and swimming at the Black Sea beach is at your own risk: there are no lifeguards, and the currents are treacherous.

Activities recommended by the park administration include photography, birdwatching, ecotourism, easy hiking trails through the forest and dunes, and picnics at specially equipped sites. The best months for birdwatching are the migration periods (late March–April and September), when flocks of storks and birds of prey fly over Strandzha. The local cuisine is seafood-based: on the coast, they serve fresh anchovies, horse mackerel, and flounder, either simply grilled or in the form of Thracian flatbreads, while in the forest villages, you’ll find homemade yogurt, white cheese, and cheese pie (a legacy of the Bulgarian borderlands).

For the Russian traveler, the floodplain forests of Igneada are an excellent alternative to Turkey’s usual “postcard” itineraries. While Cappadocia and Pamukkale have long since turned into a tourist conveyor belt, here the feeling of a real northern forest remains, somewhat reminiscent of the Russian floodplains of the Oka or Pripyat rivers in spring, only with Turkish place names and a view of the Black Sea. Set aside a full day for the park, spend the night in the village of Igneada at a small family-run guesthouse, and don’t try to cover everything in a couple of hours—the floodplain forests of Igneada reveal themselves in the silence, in the reflections of the tree trunks, and in the measured sound of the Black Sea surf beyond the dunes.

Frequently asked questions — The Floodplain Forests of Igneada: the Longoz Forest and the Kyrklareli Lakes Answers to frequently asked questions about The Floodplain Forests of Igneada: the Longoz Forest and the Kyrklareli Lakes. Information about the service's operation, capabilities, and use.
A floodplain forest is a deciduous forest that is periodically flooded during the high-water season. The trees—ash, alder, oak, and beech—grow directly in the floodplain and tolerate periodic flooding without difficulty. Such ecosystems disappeared in most European countries as early as the 19th and 20th centuries due to land reclamation. The floodplain forests of Igneada are one of the last surviving examples of such forests in the entire Mediterranean-Black Sea region, which is what makes them special.
Admission to the park is free. A small fee may be charged for parking at some viewing areas, but it is nominal. There are no admission tickets.
No, swimming in the park’s lakes is prohibited—it is a protected natural area. On the Black Sea beach behind the dunes, swimming is technically allowed during the warmer months; however, the currents there are strong and treacherous, and there are no lifeguards. The park administration recommends exercising caution.
This is a real problem, especially in the summer. The park is located in a marshy area, and without insect repellent, a visit to the floodplain forest and the lake shores will turn into an ordeal. Insect repellent is a must-have item in your gear list at any time of year, except perhaps on freezing winter days.
The park is home to a rich variety of wildlife. Among the birds are the white-tailed eagle, black stork, gray heron, kingfisher, green woodpecker, and hoopoe. Among the mammals are the otter, wildcat, badger, wolf, red deer, and wild boar. Trout and smelt are found in the rivers and lakes, while anchovies, flounder, and horse mackerel inhabit the sea. Reptiles include the Balkan tortoise and Karelin’s newt.
The most famous is Lake Mert (Mert Gölü), covering an area of 266 hectares—it is the park’s largest body of water. It is here that a wooden walkway has been built over the water, offering a view of tree trunks reflected in the mirror-like surface. This view has become a sort of “postcard” image of Igneada. Erikli Lagoon is notable for an unusual phenomenon: in the summer, it becomes cut off from the sea and turns into a separate body of water.
The park has minimal infrastructure: wooden walkways, observation decks, designated picnic areas, and a small environmental education center. There are almost no cafes inside the park—just a few simple eateries in the village of Igneada itself. It’s best to bring your own food and water.
Yes, birdwatching is one of the main reasons ornithologists visit Igneada. The best times are during migration: late March through April and September, when flocks of storks and birds of prey pass over the Strandzha Mountains (Yıldız Dağları). For birdwatching, it is recommended to bring binoculars and walk along the shores of Lake Mert and Lake Erikli in the early morning hours.
Unlike most Turkish parks, which are set against mountainous or Mediterranean landscapes, Igneada is a Black Sea floodplain with a floodplain forest—a feature more commonly associated with Eastern Europe than with Turkey. Here, lagoons, dunes, marshes, and the open Black Sea coast coexist—a combination rarely found in a single location. Moreover, the park remains virtually untouched by mass tourism; the trails are deserted even on weekends.
The cuisine of the village of Igneada centers on seafood: fresh anchovies, horse mackerel, and flounder, served grilled or in Thracian-style flatbreads. In the villages near the park, you’ll find homemade yogurt, white cheese, and banitsa with cheese, a dish inherited from the Bulgarian border region. The best way to enjoy these dishes is for dinner at one of the family-run guesthouses or small fish cafes in the village.
The park’s main attractions—the lakes and wooden boardwalks—are well-marked and easily accessible on your own. A solo visit is entirely feasible if you have a car and a basic supply of water, food, and insect repellent. For a more immersive experience in the forest or for birdwatching, local guides are available through guesthouses and environmental clubs.
Yes. Good options include Edirne and Sinan’s mosques (about two hours from Igneada via Kırklareli) or the Black Sea coastal villages in the province of Kırklareli. If you’re traveling from Istanbul, the route goes through Çorlu and Lüleburgaz—you can make short stops along the way. The park itself takes a full day to explore, so it’s more convenient to stay overnight in Igneada and continue on the next day.

The best times to visit are late spring (April–May) and early fall (September–October). In the spring, the floodplain forest is partially submerged, and the foliage is fresh—this is when you can capture “mirror-like” shots with reflections of the trees. In the fall, the forest turns shades of gold and copper, and there are noticeably fewer people. Summer is hot, humid, and full of aggressive mosquitoes. Winter is picturesque, but some of the boardwalks may be closed.
From Istanbul—about 250 km, roughly a three-hour drive on the O-3 highway through Saray and Vize, then through Poyralı and Demirköy. This is the most convenient option: the park’s sites are spread out 5–10 km apart, and you can’t get between them without a car. Without a car: take a bus from the Istanbul Bus Terminal (Otogar) to Kirklareli or Demirköy, then a dolmuş to the village of Igneada—a total of 4–5 hours with transfers. From Edirne—about two hours via Kirklareli and Demirköy.
Essentials: waterproof shoes (the wooden walkways extend into the water in some places), strong mosquito and midge repellent, a supply of drinking water and snacks (there are no cafes inside the park), binoculars for birdwatching, and a raincoat or windbreaker during the off-season. During the warm season—sunscreen and a hat for walking through the dunes.
A convenient itinerary: start with Lake Mert (Mert Gölü)—take a walk along the wooden boardwalk over the water, surrounded by the trunks of the floodplain forest (30–40 minutes). Then Erikli Lagoon (Erikli Gölü) in the north—especially beautiful at sunset when the herons gather. If you have time, visit the small lakes of Saka, Hamam, and Pedina in the southern part of the park for some solitude and a chance to spot an otter or a black stork.
A 10-kilometer strip of dunes, home to endemic plants, stretches from the forest to the sea. A walk through the dunes to the open Black Sea coast is a separate 20–30-minute route. The beach, with its dark sand and pebbles, is practically empty. Swimming requires caution due to strong currents—there are no lifeguards. However, it’s an excellent spot for photography and walking.
The park reveals its beauty in the quiet and cannot be fully appreciated in just a couple of hours. The best plan is to spend the night at one of the family-run guesthouses in the village of Igneada. In the evening, enjoy dinner at a local seafood café: fresh anchovies, flounder, or horse mackerel. The next morning, head out to the lakes at dawn—it is during the early hours that the birds are most active, and the water is as smooth as glass.
