    Hiking

    Built in 1970, the Arzal dam allows the regulation of the waters of the Vilaine and the storage of drinking water for the inhabitants of the region. Its construction allowed the expansion of the port of Arzal, a gateway for boaters who wish to sail in the estuary or on the Vilaine.

    This is an artificial dam on La Vilaine. There is an information board with the history of this structure.
    Here you can consult information on the lock times:

    Hiking

    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.
