Changu Lake, also known as Tsomgo Lake, is one of Sikkim’s most visited attractions, and snowfall is one of its main highlights. The best time to witness snowfall at Changu Lake is from late November to March, when temperatures drop below freezing. During this period, the entire landscape gets covered with thick layers of snow, making it a magical winter destination. Tourists visiting in December and January are almost guaranteed to experience heavy snow and even see the lake partially or fully frozen.
