Chadar Trek (Zanskar River)

The Chadar Trek is a specialized winter expedition on the frozen Zanskar River in Ladakh. Historically known as the 'Chadar' (blanket of ice), this route served as the primary winter link between the Zanskar Valley and Leh when high mountain passes were impassable due to snow. This trek features non-technical terrain, but an extreme environmental load. The route involves traversing the ice surface within deep limestone canyons. With ambient temperatures frequently dropping below -30°C, the trek requires specialized cold-weather management and an understanding of shifting ice dynamics.

One of the most frequented day hikes from El Chaltén, the route to Laguna Torre leads to a glacial lake at the base of the Torre massif. The 18 km out-and-back trail follows the Fitz Roy River valley, moving through sub-antarctic forests of ñire and lenga. The terrain is primarily well-maintained gravel paths and packed dirt, with a short initial ascent followed by mostly level walking through the glacial valley. The destination offers direct views of Cerro Torre (3,128m) and the Adela range, with icebergs frequently calving from the Torre Glacier into the lake.
