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.

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.
