The State National Natural Park «Kolsai» is the youngest of the specially protected areas in the Tien-Shan Mountains in Kazakhstan. The total area of the park is 161,045 ha.
The park is located in north-eastern part of the Tien-Shan Mountains which includes the northern slopes of the eastern Kungei Ala-Tau. The park is situated at the altitude of 1800-3500 m above the sea level and has the unique landscapes with a cascade of lakes, rich flora and fauna and still conserves some huge parts of wild and untouched nature. The main attraction of this natural park is a cascade of the three great Kolsai lakes located in a beautiful valley surrounded by very high mountain peaks. All the three unique mountain lakes are of the tectonic origin - Upper, Middle and Lower Kolsai lakes are located respectively at 1870, 2250 and 2650 meters above the sea level. All of the Kolsai lakes are very deep. The deepest place is 80 meters.
In the next valley there is one more incredibly beautiful mountain lake called Kaindy situated at the altitude of 1,867 meters above the sea level and surrounded by mountain peaks. The lake was formed only 100 years ago and it's also of the tectonic origin. The lake is very interesting and mysterious because of a plenty of Tien-Shan spruces growing right inside of it. It's understandable that such a natural paradise attracts people from all over the world.
