Breton rivers and canals form a network of more than 600 km of navigable waterways reserved for leisure activities and boating.
There are Two Main Routes
The English Channel-Ocean link: running north-south and comprising the maritime Rance, the Ille–et-Rance canal, the canalised section of the river Vilaine and the maritime Vilaine, this in turn runs through Dinan, Rennes, Redon and Roche-Bernard.
The Nantes-Brest canal: covering 360 km and running from east-west along in turn the Erdre, the Isac, the Oust, and the Aulne. On leaving Lorient, a cruise along the Blavet, the eastern section of the Nantes-Brest canal and the Erdre will allow you to explore Josselin and Redon before reaching Nantes.
