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.

The Apolobamba Traverse is a remote, high-altitude backpacking route in the northern Bolivian Andes. Spanning approximately 92km between the villages of Pelechuco and Curva, the trek crosses the ancestral territory of the Kallawaya people—traditional herbalists recognized by UNESCO. The route follows ancient stone paths and animal trails, staying almost exclusively above 4,200m. It traverses several high passes, including the 5,100m Sunchuli Pass, offering direct views of the 6,000m peaks of the northern Apolobamba range. Due to its distance from major cities, it remains one of the least-trafficked and most preserved regions of the Bolivian Andes.
