Nestled like a turquoise jewel at 12,400 ft amid the rugged Eastern Himalayas, Tsomgo Lake (locally Changu) is Sikkim’s most iconic glacial lake – a sacred mirror fed by melting snow that freezes solid in winter and blooms with rhododendrons in summer. Just 40 km from Gangtok, this 1-km-long oval is revered by Buddhists as the abode of spirits, with Brahma ducks migrating annually and prayer flags fluttering in the crisp mountain air. From yak rides along the shore to sipping hot tea at 3,780 m, Tsomgo offers breathtaking 360° views of jagged peaks. A high-altitude contrast to Dumboor’s lotus islands, it is Sikkim’s postcard-perfect day trip. For visitors to indiatourisminfo.com, Tsomgo is pure Himalayan magic. With 2025 cable car access and the Tsomgo Winter Festival, this “Source of the Lake” is an unmissable destination for nature lovers, photographers, and adventure seekers.
