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.

Technically Stage 8 of the Swiss Via Alpina, this traverse crosses the border between the Cantons of Glarus and Uri. Starting at Urnerboden—Switzerland's largest alpine pasture—the trail climbs toward the Klausenpass before a massive, spectacular descent into the Schächental valley. The path stays high on the sunny northern slope (the 'Schächentaler Höhenweg'), offering constant views of the jagged Glarus Alps and the limestone spires of the Schärhorn. It is a hike of immense scale and pastoral charm, passing through active cheese-making settlements.
