Vallée de Douvenant

Located to the east of the town, the Douvenant valley stretches for 5 km to the Grève des Courses.

A wild, largely undeveloped valley, it marks the border between Saint-Brieuc and Langueux.

The curved Douvenant viaduct, built by Harel de la Noë for the railroads, has overlooked the valley since 1905. Rehabilitated in 2022, it is now open to pedestrians and cyclists, offering an exceptional view of the Bay of Saint-Brieuc.
