The church of Saint-Senoux, rebuilt in 1896 in a Romanesque-Byzantine style, is distinguished by its onion-domed bell tower and vaulted nave. It reuses elements from the old church and retains the original altars, baptistery and confessionals.

Located at the confluence of the Vilaine and Semnon rivers, this picturesque little village is surrounded by valley landscapes in a verdant setting. The village boasts a charming local heritage with its old houses and its bridge over the river.

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.

Redon has managed to retain its quiet, small-town character, despite its intense activity (and traffic). Following the floods of 2024, the campsite is closed. The pedestrian street is pleasant and not overcrowded with shops. Just what you need. A visit to the port is also a pleasant experience.

Hello everyone, The bridge has been dismantled for two years, undergoing repairs in the navigation workshops. I hope to see it again one day.

Magnificent viewpoint that is well worth the stop, which also allows you to catch your breath on the short false flat followed by a short climb again. In the opposite direction, if you don't let yourself get carried away by the descent...
