Lachen is a town in Mangan District in the Indian state of Sikkim. It is located at an elevation of 2,750 metres. The name Lachen means "big pass". The town is being promoted as a tourist destination by the Sikkimese government. The town forms the base to the Chopta Valley and Gurudongmar Lake. An annual yak race, the Thangu is held here in summer. Unlike other places in India, Lachen has its unique form of local self governance called the “Dzumsa”. Every household is a member of this traditional administrative system, this institution is in charge of governing and organizing activities within the village. Visits to the Lachen monastery and the women's handicraft centre to view weaving of traditional blankets and carpets will provide insights into the local way of life. The sacred Gurudongmar lake at a height of 17,800 ft is encircled by snowy massifs. One can stay over night at Thangu which is 30 km away from Lachen. During summer and monsoon the entire place is dotted with flowers of all kinds. The relatively unexplored and untouched Chopta Valley is located in north of Lachen. Rich with alpine vegetation and rhododendrons, enthralling lakes and rivers add to the beauty of Chopta Valley. Chopta is also famous for the several monuments of historical and religious importance. Wildlife enthusiasts can spot rare species of animals, plants and birds in the Chopta Valley. Bird watching is a popular activity and the region is suitable for trekking and other adventure sports.[
