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 tropical frontier. Xishuangbanna, located in the southernmost tip of Yunnan province bordering Laos and Myanmar, is the only place in China where you can find a true tropical rainforest. This region is the ancestral home of the Dai people and home to China's last wild Asian elephants. Hiking here involves trekking through dense canopy, crossing muddy rivers, and visiting remote tea-growing villages. It is a world away from the high-altitude glaciers of the north, offering a lush, humid, and biodiversity-rich adventure.
