Nahuel Huapi Traverse (4 Refugios)

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.

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.
