It is the second largest lake in Kyrgyzstan (18x29km wide, 13 meters deep) after Issyk kul. Its name, meaning "following lake", is popularly considered to refer to this relation. It is surrounded by a broad summer pasture and then mountains. The area is inhabited and safely accessible only from June to September.
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. CBT can arrange return transport for $80-$100 per car from their offices in Kochkor or for a much higher price from their office in Bishkek. Some companies like Iron Horse Nomadscan bundle the transportation from Bishkek with CBT housing and an English speaking driver who stays with you with prices starting around $350. Agencies can also organize foot or horse treks to the lake.
Climb the mountain behind the yurts for a great view over the lake. Takes several hours to get to the top.
There are no facilities on the lake, but local herders will provide supplies and rent yurts for about $14 per night including meals. Agencies, including CBT, can arrange these in advance but it is also possible to just show up.
