Changu Lake, Sikkim – A Comprehensive Travel Guide

9010 1

Changu Lake, also called Tsogmo Lake or Tsonmgo Lake or Tshangu Lake is a glacial lake which interestingly translates to ‘Head/Source of Lake’ in Bhutia language. Located in East Sikkim district 40 km from Gangtok, the capital of Sikkim, this beauty in blue is perched at an altitude of 3780 m. The azure colour of the lake turns into white of ice in winters. The journey to this one of the most beautiful lakes of Himalayas is highly adventurous, as the road is quite steep and gains elevation rapidly. As you take the journey, you have a rendezvous with history, since this was the Old Silk route before 1962.

Nathula Pass

The Nathu La is a Himalayan Pass that connects Indian border to the border of Tibet in China. It was sealed in 1962 after the Indo- Sino war, but was reopened in 2006. Its elevation is 4310 m and the presence of oxygen is low. Since Nathu La is a restricted area, only Indian tourists are permitted to visit here, that too with special permits. What makes it more exotic is the fact that the pass lies on the old Silk route.
