Changu lake mostly remains frozen from December - March and the view is mesmerizing. As the lake is situated in the restricted zone we need permit and booked a cab with a local travel agent. For permit you need 2 passport size photo and Rs. 200 per person for Indian Nationals.
We started at 9am to explore the lake. It's 2-3 hours rode from Gangtok city centre. The weather in Gangtok was cold but pleasant. Infact the day, I reached Gangtok at that time it was raining for 2 days. However as we began to ascend, the temperature dropped was around 1-2 Degree Celsius. Climate forced me to buy thick jacket and Iceland boots from a Chai-Maggie point.
Sadly, I couldn't visit Nathula Pass since the roads were blocked due to heavy snowfall and bad weather. But once I reached the lake view was mesmerizing.
This unforgettable memories of Tsomgo Lake will last forever.
