Song Kol (also Son Kul, literally "following lake") is an alpine lake in northern Naryn Province, Kyrgyzstan. It lies at an altitude of 3016 m, and has an area of about 270 km2 and volume of 2.64 km3. Lake's maximum length is 29 km, breadth about 18 km, and extreme depth of 13.2 m. It is the second largest lake after Issyk Kul Lake, and the largest fresh water lake in Kyrgyzstan. Its name, meaning "following lake", is popularly considered to refer to this relation. It is surrounded by a broad summer pasture and then mountains. Its beauty is greatly praised, but it is rather inaccessible. The best approach seems to be the 85 km road from Sary-Bulak on the main north-south highway. Other routes require 4x4s. There are no facilities on the lake, but local herders will provide supplies and rent yurts. The area is inhabited and safely accessible only from June to September.
