Tour du Cézallier (Vaches Rouges)

MODERATE // CHLG
Full Route Report

Known as the 'Tour des Vaches Rouges' (Tour of the Red Cows), the Tour du Cézallier is a deep dive into France's most isolated, windswept volcanic plateau in the Auvergne volcano region. Tucked between the Cantal and Sancy mountains, this 135km loop offers an experience vastly different from the Alps—a vast, rolling ocean of high-altitude grasslands (estives), peat bogs, and glacial lakes. It is a hike defined by total silence, minimalism, and the rhythm of the wind. 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.

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
Tour du Cézallier (Vaches Rouges)
MODERATE // CHLG
navigation in dense fog: The Cézallier is notoriously exposed. Sudden, dense fogs (brouillard) can drop visibility dramatically, making the featureless grasslands disorienting.
wind chill and weather shifts: Informally nicknamed the 'Auvergne Siberia', the plateau is open to powerful westerly winds that can cause temperatures to drop rapidly even in summer.
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.
