GR R2 — La Grande Traversée

The GR R2 is a legendary long-distance trail that traverses the French island of Réunion in the Indian Ocean from north to south. It is widely considered one of the most physically demanding GR trails in the French network due to its extreme verticality and tropical environment. The route crosses the three massive 'Cirques' (natural amphitheaters), climbs the highest peak in the Indian Ocean (Piton des Neiges, 3070m), and borders the active volcanic zone of Piton de la Fournaise.

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.
