Piuquenes Pass (Andes Crossing)

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.

Touching the sky above the White City. Volcán Misti (5,822m) is the symbolic guardian of Arequipa. While the climb is non-technical, it is a strenuous test of physical stamina and high-altitude adaptation. The 2-day journey begins with a 4x4 approach to the trailhead at 3,400m. From there, hikers endure a steep, zig-zagging climb through slippery volcanic ash and loose scree to reach a high camp (Nido de Águilas) at 4,600m. The summit push usually happens in the freezing darkness of 2:00 AM, leading to the giant crater rim where sulfur fumes and a massive iron cross mark the top. Standing on the summit, you are at an altitude equivalent to many of the world's highest mountains, with a panoramic view that stretches to the Pacific coast on clear days.
