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.

The classic 3-day Sham Valley route is a beautiful, cultural trek often called the 'Baby Trek' because of its lower altitude, short daily distances, and absence of river crossings. It takes you through the agricultural villages of Likir, Yangthang, Hemis Shukpachan, and Temisgam, ending near the famous Alchi Monastery. This trail is less about wilderness and more about walking from village to village, sleeping in family-run homestays, and sharing tea in shaded apricot orchards.
