Nahuel Huapi Traverse (4 Refugios)

EXTREME // LETHAL
Full Route Report

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.

Sky Rim Trail

EXTREME // LETHAL
Full Route Report

The Sky Rim Trail is Yellowstone National Park's premier alpine ridge traverse, providing an experience completely unlike the park's famous geyser basins or crowded roadside viewing areas. Located on the remote northwestern boundary defining the border between Yellowstone (Wyoming) and the Gallatin National Forest (Montana), this grueling 21-mile loop acts as a 'roof' over the park. Hikers ascend steeply from the valley floor to a continuous, undulating ridgeline that remains above 9,000 feet for over 7 miles. The trail precariously hugs drop-offs, crosses massive grassy saddles, and summits several distinct peaks (including Big Horn Peak), offering unparalleled 360-degree, 100-mile views of the Absarokas, the Tetons to the south, and the Madison and Gallatin ranges in Montana.

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
Nahuel Huapi Traverse (4 Refugios)
EXTREME // LETHAL
technical scrambling and exposure: Portions of the route, particularly the section between Jakob and Laguna Negra, involve steep terrain with significant fall potential and Class 2-3 scrambling sections on loose rock.
mountain weather variables: The ridgelines are fully exposed to regional weather systems. High winds, temperature drops, and sudden precipitation can occur regardless of the season.
Route B // Hazard Verdict
Sky Rim Trail
EXTREME // LETHAL
grizzly bears: The Gallatin Range is dense grizzly habitat. Bears frequently traverse the high saddles looking for army cutworm moths in the talus slopes.
lightning and exposure: The 7-mile ridge is fully exposed above the tree line. If a thunderstorm rolls in, you are the highest point holding a metal trekking pole, and there is no fast route down to safety.
