Description
A short introductory walk to see our natural heritage: Les Oulles du Diable! The circuit will take you on a shaded ascent as far as the traditional hamlet of Les Portes. After that, you cross the Navette torrent and its giant boiling devils’ cauldrons, the "Oulles du Diable", across the Romanesque Oulles bridge. The result of incredible natural forces, the Oulles du Diable are one of the marvels of the Valgaudemar valley. But take care with this dangerous torrent. Go up to the village of Les Portes, then make for Pont des Oulles and descend as far as the bridge. On the way back, follow the path along the right bank.
Difficulty
Official rating: very easy, by Parc national des Écrins.
