Tsomgo Lake

Tsomgo Lake, also known as Changu Lake, is a glacial lake situated at about 3,780 metres altitude in Gangtok District, Sikkim, near Sherathang on the Jawaharlal Nehru Road to Nathu La. Fed by melting snow, the oval-shaped lake reflects surrounding snow-capped mountains and changes colour with seasons. Revered locally and known for yak rides and winter snow scenery, it is one of Sikkim's most visited high-altitude attractions, about 38 km from Gangtok.

Visitors can expect a high-altitude oval glacial lake surrounded by steep, snow-covered mountains and alpine slopes. The lakeside has a promenade area, small shops and food stalls, and decorated yaks for rides. In winter the lake is often frozen and snow-covered, while in spring and summer the surroundings show alpine flowers and clearer reflections. Views are weather-dependent and access is controlled via check posts.

Located on the historic Nathu La trade route that once connected Sikkim with Tibet, the lake area served as a halting point for traders and yak caravans. The present Jawaharlal Nehru Road follows the alignment of this old Silk Route.

Considered sacred by local Sikkimese Buddhists and Hindus, the lake is revered as a holy water body. Traditionally, Buddhist lamas studied the lake's changing colours for divination, and local communities offer prayers at the site.
