Lachen
The road to Gurudongmar and Chopta Valley
About Lachen
Lachen is the quieter of the two North Sikkim villages, set in a narrow valley on the road towards the Tibetan plateau. Days here start extremely early, because the drive to Gurudongmar has to be finished before the wind picks up.
The altitude is significant and the terrain is exposed, so this leg of a Sikkim trip is planned with acclimatisation and a fallback in mind.
Top attractions
Gurudongmar Lake
A high sacred lake at roughly 5,400 m, weather and permit permitting.
Chopta Valley
A broad alpine valley on the way up, often the alternative when the lake road is closed.
Lachen Monastery
The village monastery above the main street.
Thangu Valley
A grazing settlement on the high road, usually a short stop.
Best time to visit
April to June
The most reliable window for reaching the lake.
October to November
Clear skies, very cold mornings.
How to reach Lachen
- Roughly six hours by road from Gangtok, on a Protected Area Permit.
- Often combined with Lachung on a five or six day Sikkim itinerary.
Good to know. Gurudongmar Lake is above 5,000 m. Access depends on the administration, weather and individual fitness, and it is never guaranteed.
