Colca Canyon (Cabanaconde to Sangalle)

Descending into the earth's crust. Colca Canyon is one of the deepest canyons in the world (3,400m). The classic trek starts in the high Andean town of Cabanaconde (3,280m) and involves a rapid, knee-jarring descent to the Colca River. Hikers pass through traditional Quechua villages where pre-Inca terraces are still active, before reaching the Sangalle Oasis—a lush, green sanctuary at the canyon floor. The return journey is an infamous pre-dawn 1,200m vertical climb that tests the lungs and legs of every hiker. Above, the sky is often filled with the massive silhouettes of Andean Condors, utilizing the morning thermals to rise out of the canyon's depths.

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.
