Why September here
A high seasonal village of yak herders on the Gurudongmar road, green only in summer.
Thangu is a high seasonal settlement at about 13,500ft where Lachenpa herders bring yaks for the short summer: cabins, an army checkpost and a valley that turns from white to gold-green for a few months.
What to do
Summer gold
The valley’s brief green season, Jun-Aug.
