Pico Aneto — The Monarch of the Pyrenees

Standing at 3,404 meters, Pico Aneto is the highest peak in the Pyrenees and the third-highest in Spain. Located in the Maladeta Massif within the Posets-Maladeta Natural Park, it is a legendary destination for mountaineers. The ascent is a strenuous high-altitude undertaking that transitions from the lush valleys of Benasque to a stark, lunar landscape of granite and perennial ice. The route is defined by two iconic challenges: the crossing of the Aneto Glacier—the largest remaining glacier in the Pyrenees—and the crossing of the 'Paso de Mahoma' (Mohammed's Bridge), a narrow, exposed rocky ridge leading to the summit cross.

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.
