The Yedigöller National Park (Turkish: Yedigöller, "seven lakes") also known as Seven Lakes National Park is located in the northern part of Bolu Province in Turkey.[1][2] The park is categorized under IUCN II and was established in 1965.[3] The park is best known for the seven lakes formed by landslides and for its profusion of plant life.[1]


Stream at Deringöl

The park is located at an elevation of 900 metres (3,000 ft) in Mengen district in the north of Bolu Province and to the south of Zonguldak in the western Black Sea region. Established in 1965, it encompasses an area of 1,623 hectares (4,010 acres).[1][4] There are seven lakes in the park which were formed due to landslides.[5] The seven lakes are Büyükgöl, Deringöl, Seringöl, Nazlıgöl, Sazlıgöl, Incegöl and Küçükgöl.[1] Several streams flow through the park some of which have handcrafted bridges across them and a small water fall.[1][6]

The park is located between Istanbul and Ankara. Access is from the Yenicaga road, 152 kilometres (94 mi) from the Ankara – Istanbul highway. During the winter the alternate road is only from the Yenicaga – Mengen – Yazicik road.[6] It is 42 kilometres (26 mi) to the north of Bolu. Kapankaya mountain peak is within the park and provides a vantage location to view the scenic beauty of the park. It is accessible all through the year.[1]

The park also has trekking paths and camps to stay,[4] in the form of tents, caravans, rest houses and bungalows.[6] There are also hot springs in the park, and the ski centers here are well known in Turkey.[1]
