Zanskar River#Sight Seeing
The Zanskar River is a north-flowing tributary of the Indus. In its upper reaches, the Zanskar has two main branches.
Lower (northern) sections of that gorge are popular in summer with tourists making rafting trips, typically from Chiling to Nimmu. In winter when the road to Zanskar is closed by snow on the high passes, the only overland route to Padum is by walking along the frozen river, a multi-day hike that is now sold as an adventure activity called the Chadar ('ice sheet') Trek.
