Experience and Caution on the Route

Due to the road's sharp curves and significant altitude gain, travelers are advised to eat lightly to avoid discomfort from altitude-induced nausea.

Tsomgo Lake's Significance and Beauty

This serene lake, whose name means "source of water" in the Bhutia language, is deeply revered by the Sikkimese. Reflecting different colors with each changing season, Tsomgo offers a mesmerizing spectacle, especially during winter when it remains frozen.
