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 Sentier Blanc-Martel is widely considered the most iconic and comprehensive day-hike within the Gorges du Verdon, situated in the Parc Naturel Régional du Verdon. This 16km point-to-point route descends into the base of the canyon, following the Verdon River as it winds through towering 700-meter limestone walls. The trail features a mix of rugged riverbed paths, engineered sections like the 252-step Brèche Imbert metal stairs, and several historical rock tunnels. It is a physically demanding trek that requires sustained effort, adequate water preparation, and comfort with steep, exposed sections. Note: Compiled from public sources — not a field report.
