GR5 — Grande Traversée des Alpes

The French section of the renowned GR5 (which technically starts in the Netherlands) serves as the 'Grande Traversée des Alpes' (GTA). This majestic 385-mile (620km) route is Europe’s classic north-to-south Alpine traverse. Starting from the shores of Lake Geneva (Lac Léman) in Thonon-les-Bains, it drives straight south through the heart of the Alps—crossing the Mont Blanc massif, the Vanoise National Park, the Queyras, and the Mercantour National Park—before finally dropping into the Mediterranean Sea at Nice. It takes about 4 weeks to complete, offering a journey from green, pastoral dairy country through high-altitude wilderness, culminating in the lavender-scented maritime Alps.

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.
