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.

Considered a premier multi-day trekking route in Los Glaciares National Park, the Huemul Circuit provides a circumnavigation of Cerro Huemul near El Chaltén. The route crosses two significant passes—Paso del Viento and Paso Huemul—offering direct panoramas of the Southern Patagonian Ice Field. Terrain varies from forested valley floors and river crossings to exposed glacial moraines and high-altitude scree slopes. The circuit is defined by its remoteness and the requirement for technical river crossing skills using fixed steel cables.
