With an altitude of 17,800 feet, this is the second-highest lake in Sikkim. The Gurudongmar lake is a mirror of Sikkim’s natural beauty. Located just 5 km north of the Kunchenjunga range, this stunning lake feels like a postcard come alive. When it is frozen in winter, you feel as if you’re walking above the clouds as you gaze across the lake. Quite simply, this is one of the most beautiful places to go in Sikkim.
