Circuit le Trou de l'Enfer

Hidden treasures of La Bernerie-en-Retz: a sunny walk at low tide ☀️

Looking for an unusual nature break in La Bernerie-en-Retz? Take advantage of low tide to discover the hidden wonders of the coast: secret coves, little caves and relics of the past await you for an unforgettable walk! ‍
Set off on an adventure at low tide from the main beach at La Bernerie towards Pornic. Let yourself be guided by the song of the waves and admire the spectacular scenery revealed at every step :

Walk along the multicoloured cliffs, sculpted by time and the elements, and take in the breathtaking ocean views.
Explore the small sheltered coves, veritable havens of peace and natural treasures: shellfish, seaweed and small crustaceans.
Dare to peer into the mysterious caves carved out by the sea, and imagine the stories and legends they contain.

As you walk along, observe the marine life that thrives in the saltwater pools: anemones, crabs and small fish hide there, taking advantage of this unique microsystem.
Near the small beach of La Rinais, you will discover the remains of a tap embedded in the cliff. This is where curists used to come to drink the ferruginous water, renowned for its beneficial properties.
Continue your exploration as far as Plage de la Boutinardière, where you'll be amazed by the Trou de l'Enfer, a golden rock pierced right through 🪨. The wind rushes through this cavity and produces a unique sound, like a dull roar, which has given it its legendary name.

Along the way, don't miss :


The fish locks, visible at low tide from the Boutinardière beach, remnants of a time when fishing was a vital activity for the villagers.
The Voruz Tower, an ancient watchtower located between the Rinais beach and Crève Coeur, offering an exceptional panoramic view of the coast.
The orange cliffs, which colour the landscape with their warm tones and add a touch of magic to the walk.


A little something extra: nearby, a 2km "accessible to all" circuit runs around the lake, ideal for a family walk or for relaxing and admiring nature ‍‍.
