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.

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.

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
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.
