Set off at low tide from the large beach of La Bernerie towards Pornic. Walk along the multicolored cliffs, pass the small coves. Dare to look in the caves dug by the onslaught of the sea. The coast is so pretty!
The puddles of water left by the sea, the small rocks covered with algae provide a home for anemones and crustaceans. Towards the small beach of Rinais you will find the remains of a tap embedded in the cliff. It is here that curists came to drink the famous ferruginous water at the beginning of the 20th century.
You arrive at Boutinardière beach at the end of which you see and hear the famous Trou de l'Enfer. This golden rock pierced right through offers a very particular sound when the wind blows. This is called "the noise of hell".
Also worth seeing on the way: the fish locks (at low tide from the boutinardière beach), the Voruz tower (between the Rinais beach and Crève Coeur) and the orange cliffs.
