Extending south beyond the beach at Les Sables d’Olonne, located on the rocky coastline of Château d’Olonne, you will find the Puits d’Enfer, a deep cleft in the rock where the sea comes crashing in at high tide.
To the north, the Chaume coastline presents an impenetrable rocky facade to the onslaught of the ocean.

Stunning panoramic views along these wild coasts.
