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

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

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.

The dam itself is interesting, but the route is not ideal for cyclists.

The Arzal dam is built on the Vilaine estuary between Arzal and Camoël. It is the largest estuary dam in Europe. It is 500 meters long and has a sea wall and five gates. To allow circulation between the river and the ocean, the dam has a lock. A port is also located nearby.
