English: The lakes formed by the landslide in the national park, which is located in a very rugged area of the Western Black Sea Region, have rich vegetation resembling the "Forest Sea", the trout living in the lakes and the recreational use potential created by these values are the main sources. In the field, whose ground structure consists of serpentines and volcanic rocks, collapsed ground movements from time to time, the land structure ready to drift, are the main factors that prepare the formation of lakes. Lakes are barrier lakes where water accumulates behind as a result of sliding masses and valleys blocking their front. Some of these are interconnected with bottom leaks.
