Among many serene places, Tsomgo Lake is one of the most pristine and incredible places to visit in Gangtok. It is a glacial lake located at an unimaginable altitude of 3753m above sea level and must feature on the top of your Gangtok sightseeing itinerary just for one reason – its overwhelming scenic beauty. It has sparkling aquamarine blue waters in the summers that commence in mid-May and the periphery of this lake is dotted by beautiful blossoms that bloom during the season – a picture-perfect moment for all photographers. In the winters, the lake freezes and appears in a translucent colour. Also known as Changu Lake, a visit to this place promises you tranquillity and an impressive view!
