Situated at a height of 17,800 feet, it is considered one the most sacred lakes by the Buddhists and Hindus alike. The beautiful and awe inspiring lake (190 kms from Gangtok) remains milky in colour throughout the year. According to a legend, since the lake used to remain frozen most of the year, it was not possible to use its water for drinking purposes. When the Guru Padmasambhava passed by, while returning from Tibet, the local residents are reported to have approached him for providing source of water.
The Guru obliged. A portion of the lake touched by him does not freeze in extreme winter. Since water of the lake is considered sacred, visitors carry the 'blessed' water in bottles.
