The face of the most beautiful mountain. The Alpamayo Circuit (also known as the Cedros-Alpamayo trek) is an 11-day high-altitude trek in the Cordillera Blanca. While the technical climb of Alpamayo (5,947m) is world-famous, the circuit trek allows non-climbers to experience the mountain from all sides. The route passes through deep glacial valleys and over multiple 4,700m+ passes, offering a full 360-degree perspective of the ice pyramid that was voted 'The Most Beautiful Mountain in the World' at the 1966 Munich photo exhibition.
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.
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.
