El Caminito del Rey — The King's Path

LOW // ACCESS
Full Route Report

Once considered the most dangerous hike in the world, the Caminito del Rey (Little Path of the King) is now a spectacular, safe, and exhilarating walkway through the Gaitanes Gorge. The trail consists of steel-and-wood boardwalks suspended 100 meters high on the vertical limestone walls of the canyon. It was originally built in 1905 for hydroelectric workers and was completely restored in 2015 CE. The route offers scenic views of the Guadalhorce river, the high bridges spanning the gorge, and the fossils embedded in the ancient seabed rock.

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.

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.

Route A // Hazard Verdict
El Caminito del Rey — The King's Path
LOW // ACCESS
extreme vertigo exposure: Even though the trail is perfectly safe, the psychological impact of being suspended on a cliff can be intense.
heat reflection canyon: The Gaitanes gorge is a south-facing limestone oven; temperatures can soar above 40°C in July/August.
Route B // 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.
