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.
Puertos de Áliva — The Alpine Meadows
This is the most accessible high-alpine experience in the Picos de Europa. The route begins with a dramatic 753m vertical ascent via the Fuente Dé cable car to the 'El Cable' mountain station. From this stark limestone plateau at 1,834m, the trail descends through the 'Puertos de Áliva'—vast, rolling green meadows that feel like the Swiss Alps. The path winds past isolated mountain hotels and through peaceful beech and oak forests before returning to the valley floor at Fuente Dé.
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.
