The Green Lake Trek is situated in North Sikkim, close to the Indo-China border, and requires special permits due to its restricted location.
The trek generally begins from Lachen, a high-altitude village in North Sikkim, which serves as the primary base for the expedition.
The trek route passes through some of the most remote and spectacular landscapes in Sikkim. Starting from Lachen, the trail gradually ascends through river valleys, alpine forests, and glacial moraines. Trekkers cross high-altitude meadows, wooden bridges, and rocky terrains while following ancient mountain trails once used by local herders.
As altitude increases, vegetation becomes sparse and dramatic Himalayan scenery takes over. The approach to Green Lake offers close-up views of towering peaks such as Mt. Kanchenjunga, Mt. Simvo, Mt. Siniolchu, and surrounding glaciers. The silence, vastness, and untouched beauty of the region create a truly unforgettable experience.
The Green Lake Trek is recommended only for experienced trekkers with prior high-altitude trekking experience. Proper acclimatization, physical fitness, and mental preparedness are essential due to the altitude and length of the trek.
