Lachen

Lachen is a high-altitude Himalayan village in Mangan District (North Sikkim) at about 2,750 metres, situated on the banks of the Lachen Chu river. It serves as the main base for visits to Gurudongmar Lake and nearby valleys. Known for its traditional Lachenpa settlement, Buddhist monastery, alpine landscapes and snow-capped peaks, it is a regulated tourist destination requiring a Protected Area Permit.

Visitors can expect a small mountain village with traditional wooden houses, homestays and hotels along a single main road, surrounded by forested slopes and snow-covered peaks. The Lachen Monastery, local markets and views of the Lachen Chu valley are within the village. Most visitors use Lachen as an overnight halt before early-morning drives to Gurudongmar Lake, Thangu and Chopta valleys, experiencing high-altitude terrain, limited mobile connectivity and basic amenities.

Lachen is a traditional seasonal settlement of the Lachenpa community, a Bhutia group of Tibetan origin. Historically used as a winter grazing and trading settlement along Himalayan routes, it developed around the Lachen Monastery and retains its distinct village administration through the Dzumsa system shared with neighboring Lachung.
