Location of Changu Lake
Changu Lake (Tsomgo Lake) is located in the Changu area of East Sikkim, approximately 38–40 km from Gangtok on the historic Gangtok-Nathula Highway. Perched at an elevation of 12,313 feet, the lake lies in a bowl-shaped valley surrounded by rugged, snow-covered mountains.
In the local Bhutia language, “Tsomgo” means “Source of Water.” The lake is considered sacred by the local Sikkimese people (both Buddhists and Hindus). Its water color changes with the seasons — turquoise blue in summer, emerald green in autumn, and completely frozen in winter. The lake is fed by melting snow from the surrounding peaks and serves as the origin point for the Lungtze Chu River.
