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.

Milestone marking the boundary of the Abbey of Prières. Created between 1248 and 1252, it was located in Billiers, near the Pointe de Penlann. The abbey was largely destroyed during the Revolution. There are still a few buildings, the bell tower and a few milestones at the boundary of its domain. This milestone is the easiest to find: it is decorated with a Macle (heraldic symbol) and an Ermine (symbol of the Dukes of Brittany who founded the abbey).

A high cliff with ocher shades overlooking the sea... The two kilometer long beach will seduce you. If its colors are reminiscent of precious metal, it is not by chance. The cliff was exploited as a gold mine in the 19th century, hence its name! At the time, it aroused the wildest hopes but was closed during the First World War due to lack of sufficient output. Go for a walk there at the end of the day. In the setting sun, the orange cliff takes on all its reflections. A very beautiful show. https://www.tourismebretagne.com/destinations/les-10-destinations/bretagne-loire-ocean/la-plage-de-la-mine-dor-penestin/

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.
