Set at an altitude of 3,900 meters (12795. 2 feet) above sea level, the Chadar Trek is full of physical challenges. The 65-mile route follows through the frozen Zanskar River that is enveloped in a sheet of ice and confined within a sharp 600 meter high gorge. This trek has a sub-zero temperature, frozen river, hefty elevation, icy track, bitterly cold water underfoot and a massive amount of slipperiness, hence the added challenge. But the reward is the picturesque views of the Shanti Stupa and frozen river along the way, and the beautiful stories of the inhabitants of the Zanskar village. The beauty of this trek is its icy path, which changes colour on the Zanskar River every few hours. To walk the length of the ice sheets takes around six days, with the base point as Leh.
