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.

A pleasant little detour on the road to Pontchâteau. The Moulin de la Lande is a lovely place to stop and relax—a peaceful spot with an open view and an authentic atmosphere. Formerly a windmill belonging to the commune of Pontchâteau, the Moulin de la Lande bears witness to the region's milling past. Today, it stands in ruins.

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.

Here you cycle on the old towpath along the Nantes-Brest canal. You can see swans floating on the water.

The most touristic of the eight islands that make up the commune of Saint-Joachim, notably for its famous thatched cottages typical of Brière and its Michelin-starred restaurant, La Mare aux Oiseaux.
