The Heavenly Lake is a moraine by nature. Splendid peaks and glaciers were developed some 200,000 years ago. As a result of prolonged scouring and wearing off of the glaciers, a gigantic pit was formed. Later, the climate turned warmer, glaciers receded and a large amount of gravel accumulated, resulting in huge terminal moraines. In the end, the Heavenly Lake took shape. Since remote times, quite a few of myths and legends circulated concerning the beautiful scenery.

The water is very clear and the banks are covered with tall trees. Surrounded by mountains, the jade-green lake is an ideal place for excursions and rest for most of the year. it provides an excellent skating ground in winter.

The Kazak people mainly live in the picturesque tourist area of Heavenly Lake. Living nomadic life, the Kazak herdsmen dwell in white-colored yurts.
