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.

Selvaggio Blu

EXTREME // LETHAL
Full Route Report

The Selvaggio Blu ('Wild Blue') is a multi-day technical expedition within the Golfo di Orosei, Baunei region of Sardinia. It is defined by its vertical coastal topography, utilizing ancient juniper ladders (scale 'e fustes'), non-standard navigation across minimal signage, and often required vertical abseils (rappelling) of up to 45 meters. The circuit threads through the Supramonte coastal strip, remaining isolated from road infrastructure and requiring bivouacking on remote beaches. It represents the most demanding coastal traverse in Italy due to the absence of natural surface water and the complexity of the Mediterranean karst terrain.

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
Selvaggio Blu
EXTREME // LETHAL
technical movement and abseiling: The route includes climbing sections typically in the UIAA Grade II-III range and multiple often required rappels up to 45 meters down vertical limestone.
severe dehydration: Porous karst terrain holds zero surface water. Carrying five days of hydration while performing technical maneuvers is logistically unrealistic for most parties.
