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.

This magnificent 5.3-mile (8.5km) section of the South West Coast Path links two of North Cornwall's most dramatic locations: the mythical ruins of Tintagel Castle (legendary birthplace of King Arthur) and the historic, fjord-like harbor of Boscastle. The route is defined by the raw power of the Atlantic Ocean crashing against towering slate cliffs, deep rocky coves, and sweeping headlands. Along the way, you pass the stunning Rocky Valley—where a river has carved a spectacular gorge through the slate—and sweeping views out to Lundy Island. The constant, steep descents and ascents out of the coastal valleys (known as "coombes") make this short distance surprisingly strenuous.
