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 classic Gangotri to Gaumukh itinerary follows the headwaters of the Bhagirathi River to the true source of the Ganges. The power of this trek lies in standing at the raw, collapsing edge of the glacier, where the river that becomes the Ganges emerges from ice. Originating from the sacred settlement of Gangotri, the route transits through the Gangotri National Park. Gaumukh (Cow's Mouth) marks the terminus of the Gangotri Glacier. The landscape is defined by massive granite peaks, including the Bhagirathi massif and Shivling (6,543m), making it incredibly culturally and visually important.
