Kastamonu-Bartın Küre Mountains

Kastamonu-Bartın Küre Mountains National Park is one of Turkey's largest national parks, straddling Kastamonu and Bartın provinces in the western Black Sea region. Covering approximately 37,749 hectares, it protects one of Turkey's most extensive and biodiverse temperate forests, a remnant of the ancient Colchic forest that once stretched across the Pontic Mountains. The park is particularly noted for its old-growth Oriental beech forests, rich cave systems, and exceptional biodiversity.

The park harbours one of Turkey's healthiest brown bear populations, along with wolf, lynx, wildcat, and roe deer. Eurasian otter inhabits the river systems. The bird fauna is exceptionally rich, with 169 recorded species including the globally threatened corncrake, lesser spotted eagle, black stork, and several woodpecker species. The Kartalkaya limestone caves support important bat colonies. Trout thrive in the clear Gideros and other park rivers, and the park has one of the highest plant biodiversity counts of any Turkish protected area.

The park's forests represent some of the most intact examples of Euxine temperate broadleaf forest remaining in Turkey. Oriental beech dominates the canopy across most of the park, accompanied by Oriental hornbeam, lime, and maple. Caucasian wingnut, Pontic oak, and Rhododendron ponticum are characteristic understory species. The park contains several plant species at the western limit of their Caucasian distribution. Riparian forests along park rivers include alder, willow, and poplar. Some interior areas retain genuinely old-growth character.

The Küre Mountains form part of the northern Anatolian mountains (Pontides), composed predominantly of Paleozoic metamorphic basement rocks overlain by Carboniferous-Triassic volcanic sequences. Significant limestone karst terrain occurs in the eastern sections, with the Ilıca Cave system among the most extensive in Turkey. The Gideros River has carved deep gorges through resistant Mesozoic limestone. The region sits north of the North Anatolian Fault zone and experiences periodic seismicity.

The park has a humid oceanic climate heavily influenced by Black Sea air masses. Annual precipitation ranges from 800 mm on southern slopes to over 1,500 mm at higher elevations. Summers are mild and overcast with temperatures rarely exceeding 28°C in the forest. Winters are cold and snowy, with snowpack persisting from December to March at higher elevations. Fog is common throughout the year, particularly in valley bottoms, maintaining the constantly moist conditions favoured by the beech forest ecosystem.

The Küre region has a long history of copper mining stretching back to the Chalcolithic period; the Küre copper mines are among the oldest in Turkey and were worked through the Roman, Byzantine, and Ottoman eras. The surrounding forests were heavily exploited for charcoal production to smelt copper ore. Kastamonu city, just south of the park, was an important medieval Anatolian centre, serving as the seat of the Jandarid dynasty before Ottoman conquest in 1461.

Kastamonu-Bartın Küre Mountains was designated a national park in 2000, recognising both its exceptional ecological values and its importance as a water catchment for the region. Prior to designation, large areas had been subject to intensive commercial forestry. Since protection, natural regeneration of old-growth beech forest has been evident in previously logged areas. The park administration conducts systematic monitoring of large mammals and has cooperated with WWF-Turkey on carnivore conservation programs.

The park offers extensive hiking trails through its old-growth forests and river valleys. The Ilıca Cave system near Azdavay is one of the park's premier attractions, accessible with guides. The Gideros River valley offers scenic walking with opportunities to observe otters and dippers. Valla Canyon provides dramatic gorge scenery. Bird hides near forest clearings facilitate woodpecker and raptor observation. The town of Cide on the Black Sea coast provides coastal recreation adjacent to the park.

The park is accessible from both Kastamonu city to the south and Bartın city to the northeast, both connected by highway to Ankara and the coast. Visitor centres are located at Valla and near Azdavay. Camping areas and picnic facilities exist throughout the park. Local ecotourism initiatives offer guided forest walks and cave tours. Accommodation is available in Kastamonu, Bartın, and smaller towns within or adjacent to the park. Spring and early autumn are the optimal visiting seasons.

The park is a critical reservoir of biodiversity in the western Pontic range. Key conservation priorities include monitoring large carnivore populations, managing the boundary between the park and adjacent agricultural land, and preventing illegal hunting. The Küre copper mines adjacent to the park present potential water quality risks to park rivers. WWF-Turkey has supported habitat connectivity studies examining linkage between this park and other Pontic forest fragments, and local communities are engaged in ecotourism development.
