On the face of it, on would not expect to find lakes on such a rugged terrain. But surprisingly, Sikkim does have lakes though not very large in size. These lakes are both spring fed as well as river fed. On the highway between Gangtok and Nathu La, 34 kms. from Gangtok lies the serene Tsomgo Lake at an altitude of about 11,000 ft. . Khecheopalri lake is another well known lake that lies on a bifurcation of the route between Gyalshing and Yuksum . Menmecho lake, Green lake and Samiti lake are some other beautiful lakes.
