High tides in Brittany

6 spots to observe unique sights

In Brittany, the sea recedes every day. Six hours later, it comes back… It’s the changing of the tides. Depending on the coefficients, they can be small or big; above 100, it’s known as a high tide. From 21 to 23 August, 19 and 20 September, 18 and 19 October and 16 and 17 November 2024 , landscapes that are inaccessible the rest of the year are revealed. Be sure to get the best seats!

2. At the heart of the mussel beds and oyster farms of Saint-Cast-le-Guildo

At high tide, take advantage of the walks organised by the Saint-Cast-le-Guildo tourist information office to discover the mussel beds and oyster farms of Arguenon Bay. You can end your stroll with a tour of a mollusc company and oyster tasting! Meet at Plage des 4 Vaulx, with your boots.

3. Ploubazlanec, view of the Bréhat archipelago

From the Croix des Veuves in the commune of Ploubazlanec, you can enjoy a panoramic view of the Bréhat archipelago and, to the right, of Ile Saint Riom which will be completely uncovered.

4. Carantec, seafood collecting on Ile Callot

When the tide is low, head to Ile Callot to pick seafood from the sea bed. With a rake, a gardening claw, a fork or a spoon, you’ll find cockles, clams and periwinkles. Find out about good practices to avoid damaging this fragile environment.
Safety precautions: Check the times of the tides. Go at low water, one hour before the tide goes fully out. Wear bright colours. Make sure you have a mobile phone on you. Inform your family/friends when you go fishing. A ruler is available at the Carantec tourist information office to measure the shellfish.

5. The dunes of Keremma, a 360° view

At Pointe de Pen An Theven, on one side you can see the Keremma dunes, and on the other the granite boulder field of Plouescat.
Safety precautions: The tip is 2 metres from the ground. The risk is not major, but be careful not to get too close when the waves arrive.

6. Fouesnant, Pointe de Mousterlin and Les Glénan

When the tide is low, you can walk to Pointe de Mousterlin. It’s the ideal spot for discovering the foreshore and the wealth of a Natura 200 zone, with an exceptional 180° view of the ocean. Are you lucky enough to have a boat? Sail to Glénan: like an ephemeral gift, nature will reveal the eelgrass beds, marine plants that form real biodiversity reservoirs. A place to protect.
Safety precautions: Check the times of the tides. Go at low water, one hour before the tide goes fully out. Wear bright colours. Make sure you have a mobile phone on you.
