Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.
Refugio Jou de los Cabrones — The Limestone High
This 2-day circuit is arguably the most demanding and beautiful way to experience the Central Massif of the Picos de Europa. Starting from the isolated village of Bulnes (reached by funicular or foot), the trail ascends the 'Canal de Amuesa'—an impossibly steep limestone corridor—before traversing an undulating, high-alpine karst moonscape. The destination is the Refugio Jou de los Cabrones (2,034m), the highest and most remote managed hut in the national park, nestled in a deep limestone bowl ringed by jagged summits.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
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.
