Green Lake

The trek to Green Lake, the Base Camp of Mount Khangchendzonga on the Zemu glacier, is one of the most beautiful trekking trails in Sikkim. Green Lake is not an actual lake, but an unbelievable stretch of green frozen glacier, which is known by the name Zemu Glacier. The view of Mount Siniolchu (6,887m) there is no other mountain that can equal Siniolchu in beauty, as mentioned by Douglas Freshfield, who had seen many mountains on earth. The Green Lake trek starts from Zema 60km ahead of Lachen, a beautiful village where we set our base for this trek. Gangtok to Lachen is a day’s journey of five to six hours by car.
