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.
Mission Directive / X-Factor
“The Southern Patagonian Ice Field. Reaching the crest of Paso del Viento provides a rare, wide-angle perspective over the second-largest contiguous extra-polar ice field on Earth. The visual scale of the ice mass, combined with the transition through various Patagonian ecosystems, makes this a significant objective for experienced trekkers.”
Hazard Assessment
Winds on the high passes can be severe, particularly in summer afternoons. Gusts may make progress slow and unstable.
MITIGATION: Check local forecasts in El Chaltén before departure. Avoid attempting the passes during high-wind warnings. Maintain stable footing and use trekking poles for balance.
Two river crossings require the use of fixed steel cables (tyrolean traverses) and specialized gear.
MITIGATION: Familiarity with basic climbing equipment is required. Rangers in El Chaltén verify that hikers carry a harness, locking carabiners, and a steel pulley before allowing departure.
