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.

The Pen y Fan Horseshoe

EXPERT // HAZARD
Full Route Report

Pen y Fan is the highest peak in South Wales (886m) and the crown jewel of the Brecon Beacons National Park. While thousands stream up the 'tourist path' from the Storey Arms every day, the true mountaineer's route is the Beacons Horseshoe starting from the Neuadd Reservoir. This challenging 10-mile (16km) circular route climbs steeply onto the Craig Fan Ddu ridge, walks the long, grassy skyline over four peaks—including the 'diving board' rock at Fan y Big, Cribyn, Pen y Fan itself, and Corn Du—before descending back to the valley. It provides magnificent 360-degree views over the sheer, glaciated northern faces of the peaks down into the emerald Welsh valleys.

EXPERT // HAZARD

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.

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
The Pen y Fan Horseshoe
EXPERT // HAZARD
steep undulations: While the main ridge looks flat on a map, the saddles (bwlchs) between the peaks drop sharply and require steep, rocky climbs back up the other side.
weather exposure: The open, grassy ridges offer absolutely zero shelter against the prevailing westerly winds and driving rain.
