Lachung is a small high altitude village in the North district of Sikkim and is near the border with Tibet. Lachung is at an elevation of about 9,600 ft or 3,000 m. The word Lachung means “small pass”. The town is approximately 125 kms from the capital Gangtok.

Before the annexation of Tibet in 1950, Lachung was a trading post between Sikkim and Tibet, after which it was closed down. The town’s economy has been boosted by tourism in recent years as the region has been opened up by the Sikkimese government. Tourist come from all over the world to visit the town between October and May, mostly on their way to the Yumthang Valley and the Lachung Monastery.

During winter, the town is usually covered in snow. Lachung is also the base camp for Rhododendron Valley Trek which starts from Yumthang Valley and ends at Lachen Valley. Yumesamdong and Yumthang valley are places to visit from Lachung.
