Hire companies offer routes departing from Dinan, Hédé, Messac, Redon, Rohan, Pontivy, La Roche-Bernard and Sucé-sur-Erdre. No licence is required to pilot these boats on the Breton canals.
On arriving at the starting point, the boat hire company will welcome you onboard and guide you through the controls. The journey proceeds at a slow pace passing through locks, frequently operated by lock-keepers with no lock fees.
From the far point of the Brest roadways, it is possible to travel up the Aulne and the western section of the Nantes-Brest canal to Châteaulin and Carhaix-Plouguer.
Between Pontivy and Hennebont, the Blavet canal joins the Nantes-Brest canal at Guerlédan. The lake at Guerlédan is a huge expanse of water 12 kms long, where various water sports are available.
