Surrounded by high peaks over 3,000 metres high, the Valgaudemar valley, crossed by the turbulent Séveraisse mountain stream, is a wild and isolated area in Écrins National Park much loved by ramblers, mountaineers and fishermen.
Around La Chapelle-en-Valgaudémar, nature fans can admire stunning waterfalls like the Voile de la Mariée (bride's veil), Casset and Combefroide.
Also not to missed: Oulles du Diable, not far from the hamlet of Les Portes. This natural site offers an impressive show with the swirling water of the fast Navette mountain stream cutting its way through the rocks. A secure, dedicated footpath running alongside lets you appreciate its full beauty.
