A dam behind which thousands of pleasure boats shelter from tides, storms, and salt.

A very beautiful city, both for its iconic port at the foot of the rocks and for the old town and its charming alleys.

The port is very beautiful but even if you have to climb, the old town is also worth a visit

A fit cyclist, but not recommended in December. Beautiful route, but it's hard-earned.

In 832, Conuvoion, a Breton monk, founded the Abbey of Saint-Sauveur in Redon with the support of the Carolingian Emperor Louis the Pious. A small rural community slowly grew up around the abbey. During the Middle Ages, the town benefited from its location on the Vilaine River, as trade goods could be transported upstream to Redon on ocean-going vessels. There, the goods were transshipped and transported further on inland waterway barges towards Rennes, the capital of Brittany. In the 19th century, Redon experienced another period of prosperity with the construction of the Nantes-Brest Canal. Even today, the old shipowners' houses and the large harbor basin bear witness to its history as a trading port.

Not only can you admire the oyster beds, but you can also enjoy them fresh in several places.

It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.
