Green Lake

Green Lake is a high-altitude glacial lake in the Zemu Valley of North Sikkim at about 5,050 metres elevation at the base of Mount Kanchenjunga. Fed by the Zemu Glacier within Kanchenjunga National Park in Mangan district, it is reached only by a strenuous multi-day trek from Lachen. The lake is noted for its clear turquoise waters, surrounding alpine meadows and panoramic views of Kanchenjunga and adjoining Himalayan peaks.

Visitors reaching Green Lake after a multi-day trek can expect a remote alpine basin with a small turquoise glacial lake fed by the Zemu Glacier, surrounded by moraine, meadows and snow-covered peaks including Kanchenjunga. There are no permanent structures at the lake; the area is pristine wilderness within Kanchenjunga National Park. Visitors explore the lakeshore, glacier viewpoint and campsites, with opportunities for photography and nature viewing, all under guided trek conditions.

Green Lake and the Zemu Glacier route served as the traditional base camp approach for early Mount Kanchenjunga expeditions in the early 20th century and remains a historic mountaineering trekking route within Kanchenjunga National Park.

Located within the sacred landscape of Mount Kanchenjunga, revered as guardian deity by the people of Sikkim, and inside Kanchenjunga National Park, a UNESCO World Heritage mixed site valued for natural and cultural significance.
