The Huemul Circuit covers approximately 65 km over four to five days, with around 2,800 meters of cumulative elevation gain. The route traverses remote terrain in Los Glaciares National Park, including forest valleys, exposed ridgelines, and high glacial viewpoints.
The highest point reaches roughly 1,550 meters at Paso del Viento. While the altitude is moderate, the region is known for extreme wind exposure and rapidly changing weather conditions.
The route is non-technical but physically demanding, requiring strong endurance, experience with backcountry camping, and confidence in remote environments.
Overview
Technical Summary
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.
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.
Two river crossings require the use of fixed steel cables (tyrolean traverses) and specialized gear.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
El Chaltén to Laguna Toro
Trail passes through sub-antarctic forest and follows the Túnel River. Moderate elevation gain to reach the base camp below the passes.
Rio Túnel Crossing and Paso del Viento
Cross the first tyrolean traverse, navigate loose moraine, and climb to the 1,550m pass. Descend to the Ice Field side for camping.
Paso Huemul and Lake Viedma
Alpine traverse alongside the glacier before climbing Paso Huemul. A steep, technical descent through dense forest leads to the shores of Lake Viedma.
Return to El Chaltén
Hike along the arid steppe bordering the milky waters of Lake Viedma to reach the pick-up point or return trail.

Technical Specs
Access & Logistics
Regulations
Registration is mandatory before departure. Rangers check for a harness, two carabiners, and a steel pulley.
Seasonality
Generally accessible from November to March. Outside this period, snow accumulation and severe weather frequently make the circuit unsafe or impassable.

Route Questions
How difficult is the Huemul Circuit?
This is considered one of the most challenging treks in the region. While not a climbing route, the required use of tyrolean pulleys, navigation through moraines, and extreme wind exposure require established trekking experience.
Do I need my own pulley?
Yes. A steel pulley is mandatory for the steel cables. Aluminum pulleys will be damaged by the friction and are often rejected during the mandatory park check.
Are permits required for the Huemul Circuit?
Registration is mandatory and free. Hikers must register at the Los Glaciares National Park office in El Chaltén, where equipment is inspected and a safety briefing is provided.
