The Three Calanques — Port-Miou to En-Vau

MODERATE // CHLG
Full Route Report

Widely considered the most iconic hike in the Parc National des Calanques, this 9.5km route links the ports of Cassis and Marseille via a series of dramatic limestone inlets. The trail begins at the boat-filled Port-Miou marina, traverses the white limestone plateau, and passes the pebble beach of Port-Pin. The culmination of the route is the descent into the Calanque d’En-Vau, widely regarded as one of the most beautiful natural harbors in Europe, featuring vertical white cliffs and turquoise waters. The route combines accessible coastal pathways with steep, technically challenging descents on polished rock. Note: Compiled from public sources — not a field report.

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.

Full Scale Documentation
Route A // Hazard Verdict
The Three Calanques — Port-Miou to En-Vau
MODERATE // CHLG
extreme summer heat closure: The Calanques are highly prone to massive forest fires. During summer (June-Sept), the park is entirely closed on days with high fire risk. Even when open, the white rocks act as an oven.
polished limestone slips: The immense popularity of the trail means the limestone rocks, especially on the steep descent into En-Vau, have been polished completely smooth by millions of shoes. It is as slippery as glass.
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.
