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.

Snow Lake & Biafo-Hispar La

EXTREME // LETHAL
Full Route Report

The frozen wilderness. The Snow Lake trek is one of the world's premier high-altitude glacier traverses. Traversing the Biafo and Hispar glaciers, it covers a distance of over 120km, connecting the ancient kingdoms of Baltistan and Hunza. Snow Lake itself is a massive high-altitude ice basin (Lukpe Lawo) at 4,877m, spanning 16km in width. Surrounded by nameless granite spires and massive ice walls, this trek is a journey through a world that remains largely unchanged since the last ice age—a place of absolute silence, shifting crevasses, and monumental scale.

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.

Full Scale Documentation
Route A // Hazard Verdict
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
Snow Lake & Biafo-Hispar La
EXTREME // LETHAL
complex glacier navigation and crevasses: Both the Biafo and Hispar glaciers are highly active. Hidden crevasses, especially after fresh snow, are a severe threat.
extreme high topographical exposure: Trekkers spend over a week above 4,500m. There is zero medical infrastructure and helicopter rescue is extremely difficult and weather-dependent.
