Menmecho Lake

Menmecho Lake is a high-altitude natural lake located near Kupup in Gangtok district, Sikkim, at about 3,800 metres above sea level between Tsomgo Lake and Jelepla Pass. Fed by snowmelt streams, it is the source of the Rangpo Chu river and lies within a forested valley surrounded by mountains. Known for its clear waters, trout population and scenic setting, it is viewed en route to Nathu La and Kupup and requires a protected area permit to visit.

Visitors can expect a remote high-altitude lake set in a forested mountain valley below the Jelepla Pass, viewed from the road between Tsomgo Lake and Kupup. The lake is not directly accessible at water level for most tourists and is typically seen from a viewpoint above. Expect clear alpine waters, surrounding pine and rhododendron forests, mountain scenery, cold weather, and limited facilities. The area is part of a restricted border zone and is visited as a brief stop on the Gangtok - Tsomgo - Nathu La - Kupup circuit.

Menmecho Lake is noted as the source of the Rangpo Chu river, a tributary of the Teesta, and has been historically associated with a trout hatchery and fish farm established in the area. It lies on the historic trade route near Jelepla Pass connecting Sikkim with Tibet.
