Location of Tsomgo Lake
Tsomgo Lake lies in the Changu area of East Sikkim, approximately 38–40 km from Gangtok. At an elevation of 12,313 feet, the lake sits in a picturesque bowl-shaped valley surrounded by snow-capped mountains and rugged terrain.
In the Bhutia language, “Tsomgo” means “Source of Water.” The lake is considered sacred by both Buddhists and Hindus. Its water changes color dramatically with seasons — turquoise in summer, deep green in autumn, and frozen solid in winter. The lake is fed by melting snow and serves as the origin of the Lungtze Chu River. The surrounding area remains covered in snow during winter, creating a magical landscape.
