Lachen
The Gateway to Gurudongmar
Overview
Lachen is a high-altitude village in North Sikkim, India, at roughly 2,750 m, set in a protected zone of the Sikkim Himalaya. It is the staging base for Gurudongmar Lake, one of the highest lakes in the world at over 5,400 m, near the Tibetan frontier, and Chopta Valley. It is the deeper-altitude counterpart to Lachung. MyTripMyTravel operates Lachen as a permit-managed, medically-aware high-altitude extension of the Sikkim circuit.
Lachen is North Sikkim's far end, a village that exists, for the traveller, as the launch point for Gurudongmar, one of the highest motorable lakes on earth at over 5,400 m near the Tibetan frontier.
It is paired with Lachung but is operationally distinct: Lachung points toward Yumthang and rhododendron valleys; Lachen points up, into rarer air, frontier-controlled zones, and altitude that genuinely matters.
The protected area requires permits, military checkpoints, and pre-dawn departures for the Gurudongmar drive, and the altitude requires acclimatised pacing, neither is negotiable, both are handled.
MyTripMyTravel runs Lachen as a permit-managed, medically-aware extension from a Gangtok base, only when conditions, season, and party readiness align, with the same Sikkim chauffeured-fleet protocol that runs the rest of the circuit.

Lachen in brief
When to visit
March to mid-June, October to November
Mid-March to mid-June is the prime window, manageable temperatures and accessible Gurudongmar drive. October to November offers clear post-monsoon air. The monsoon (late June to September) brings serious landslide risk on the North Sikkim road and is avoided. Deep winter can seal the route. The altitude is genuinely high, pacing matters in any season.
