Oust Lower Valley

West of Redon, the Great Natural Site of the Lower Oust Valley stretches for 19 km and offers magnificent and varied landscapes: steep granite cliffs, woods and forests, and marshes, before joining the Nantes-Brest Canal. The Oust River marks the natural border between Ille-et-Vilaine and Morbihan.

This landscape has been developed and is now very popular with hikers and other visitors. Sights to see along the way include the Guélin Lock, the Oust Bridge, and the villages of Saint-Vincent-sur-Oust and Bains-sur-Oust. And that's not all... Just 9 kilometers from Redon, you can't miss the gem of the Nantes-Brest Canal: Île aux Pies, formed by the river and featuring natural headlands. It's a peaceful site perfect for a stroll.

You will find the lower Oust Valley near Redon, on the Peillac - Redon stage of the Vélodyssée.
