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 Travessia Petrópolis-Teresópolis is a premier multi-day traverse within the Serra dos Órgãos National Park (PARNASO). Spanning approximately 30km, the route reaches its peak at Pedra do Sino (2,263m). The trek transitions from dense Atlantic Rainforest to exposed granite plateaus. Route basics: 1. Officially known as Travessia Petrópolis-Teresópolis. 2. Located within PARNASO. 3. Requires advanced booking for 'Abrigo' shelters. 4. Iconic 'Cavalinho' scramble is the technical crux. 5. High risk of white-out fog (nevoeiro) on the ridge. 6. Best hiked between May and September.
