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 Singalila Ridge trek starts in Manebhanjan and passes through Tonglu, Gairibas, and Kalipokhri to reach Sandakphu (3,636m) and Phalut. This is one of the easiest ways to see the Everest and Kanchenjunga ranges without extreme altitude. On clear days, you can see Everest (8,848m), Lhotse, Makalu, and Kanchenjunga lined up along the horizon. The trail frequently crosses the border between India and Nepal, climbing through beautiful rhododendron and bamboo forests.
