Why October here
The Lachenpa village at 8,800ft that opens Chopta Valley and Gurudongmar Lake.
Lachen, home of the Lachenpa community, sits at about 8,800ft and opens the northern runs: Chopta Valley, Thangu and, for Indian nationals, Gurudongmar Lake at about 17,800ft. Foreign visitors may visit Lachen and Yumthang under current PAP rules but Gurudongmar is not open to them.
