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.

Zhangjiajie National Forest Park is a surreal landscape widely associated with and often cited as the inspiration for the floating 'Hallelujah Mountains' in the movie Avatar. The park is defined by over 3,000 towering, incredibly narrow quartz-sandstone pillars, many rising over 200 meters, cloaked in dense, sub-tropical jungle and frequently shrouded in mist. Hiking here involves navigating a massive, highly developed geological park. The hiking paths are heavily engineered—consisting of thousands of paved stone stairs, cliff-side walkways (including glass skywalks on Tianmen Mountain nearby), and massive outdoor elevators (like the 326m-tall Bailong Elevator).
