The rocky coast & Le Puits d’Enfer with its coastal paths: breathtaking view of the ocean!
By extending the beach of Les Sables d’Olonne to the south, located on the rocky coast of Château d’Olonne, you can discover the Puits d’Enfer, a deep fault in the cliff where the sea rushes in with a crash at high tide.
A legend is associated with this famous Well of Hell.
