Lake Abant (Turkish: Abant Gölü) is a freshwater lake in Turkey's Bolu Province in northwest Anatolia, formed as a result of a great landslide. The lake lies at an altitude of 1,328 m (4,357 ft) at a distance of 32 km (20 mi) from the provincial seat of Bolu city. It is a favorite vacation and excursion spot for both Turkish and foreign travellers thanks to the natural beauty of its surroundings, which are covered with dense forests, and easy access by car (it is served by a 21 km (13 mi) road leaving from the İstanbul-Ankara motorway O-4 or the highway D.100 at the level of Mount Bolu, three hours' drive from these two largest cities of Turkey).
