Changu lake
Direction38 km from Gangtok and at an altitude of 12,400 ft, the ethereally beautiful Tsomgo lake is a must on every visitors itinerary. A winding road through rugged mountain terrain and sharp cliffs takes you to Tsomgo, which means source of the water in Bhutia language. The lake derives its water from the melting snows of the mountains surrounding the lake. Of legendary beauty, the lake looks different at different seasons. In winter the placid lake remains frozen with the area around it covered in snow while in late spring the profusion of flowers in bloom adds a riot of colours around the lake.
