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 Ruta del Cares is Spain’s most famous hiking trail, often referred to as 'La Garganta Divina' (The Divine Gorge). Carved into the cliffs of the Cares River canyon, the path connects the villages of Poncebos (Asturias) and Caín (León). The trail follows a maintenance path for a hydroelectric canal, contouring along massive limestone walls that rise nearly 2,000 meters above the riverbed. It is a world of vertiginous drops, crystal-clear turquoise water, and herds of mountain goats navigating often not feasible slopes.
