Huemul Circuit

EXTREME // LETHAL
Full Route Report

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.

Illampu Circuit

EXTREME // LETHAL
Full Route Report

The Illampu Circuit is a demanding 6-to-7-day trek that circumnavigates the northern giants of the Cordillera Real: Illampu (6,368m) and Ancohuma (6,427m). Often described as one of Bolivia's most vertically significant non-technical routes, the loop starts and ends in the sub-tropical town of Sorata (2,700m). Much of the circuit sits above 4,000m once the Sorata valley is left behind, crossing multiple high passes including the Abra de la Calzada (~5,045m). The route crosses high-altitude pampas inhabited by Aymara herders and traverses rugged moraine fields directly beneath active glaciers.

EXTREME // LETHAL

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Huemul Circuit
EXTREME // LETHAL
extreme_winds: Winds on the high passes can be severe, particularly in summer afternoons. Gusts may make progress slow and unstable.
river_tyrolean_traverse: Two river crossings require the use of fixed steel cables (tyrolean traverses) and specialized gear.
Route B // Hazard Verdict

EXTREME // LETHAL
extreme altitude and vertical gain: The trek involves a 2,000m+ initial climb from Sorata and sustains multiple days above 4,300m, peaking at the 5,045m Calzada Pass.
weather and exposure: Night temperatures can drop to -15°C (5°F), and storms can move in rapidly.
