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.

The significant alpine link. The Routeburn Track (32km / 20 miles) is one of New Zealand's famous Great Walks, connecting the Mount Aspiring and Fiordland National Parks. Unlike some of the longer tracks, the Routeburn reaches its high point early, taking you across exposed alpine plateaus with staggering views of the Darran Mountains and the Tasman Sea. The trail winds through ancient beech forests and past jewel-like glacial lakes (Lake Harris, Lake Mackenzie), offering a concentrated experience of the best Southern Alps landscapes.
