At an altitude of 3,600 m, it is the highest lake of the Pamir plateau, near the junction of the Pamir, Tian Shan and Kunlun mountain ranges. Surrounded by mountains which remain snow-covered throughout the year, the three highest peaks visible from the lake are the Muztagh Ata (7,546 m), Kongur Tagh (7,649 m) and Kongur Tiube (7,530 m). The lake is popular among travellers for its beautiful scenery and the clarity of its reflection in the water, whose color ranges from a dark green to azure and light blue.
