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.

The cycle path along the Vilaine is truly a MUST! It runs directly along the river and has many locks. At each of the locks, there are beautifully maintained guardhouses, some of which are even kitsch. The cycle path doesn't stray more than 10 meters from the river and has a very well-maintained surface. I had the pleasure of following it for over 40 kilometers.

Very beautiful circuit starting from Missillac in the direction of Vilaine, passing successively through Thehillac, Etang Aumée, Avessac and Redon on secondary roads where there is very little traffic.

Landscape that is different from the rest of the canal. Very wild

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.
