Why October here
A holy glacial lake on the old Tibet road: yaks, prayer flags and ice most of the year.
Tsomgo (Changu) is the sacred glacial lake at about 12,400ft on the old trade road to Tibet, held holy by Sikkimese Buddhists. It freezes solid in winter, yaks pose along the shore in season, and it sits inside a protected area: Indians need permits arranged via registered agencies, and foreigners are permitted to visit under current PAP rules.
