Zanskar is one of the oldest inhabited regions of the world with wild and solitary valleys at over 13,000 ft (4000 meters) in the Himalayas. In winter, Zanskar is isolated, and only in January and February is there a way to the rest of the world: the canyon of the Zanskar River. We trek on the so called Chadar or ice covering the river from the village of Chiling to Karsha and Padum in Zanskar, and then return to Chiling.
