From Brittany's largest port to the city of the Dukes, the Canal de Nantes à Brest is a long blue ribbon that crosses inland Brittany. Although the Canal de Nantes à Brest is traditionally described from south to north-west, we're proposing a journey that goes against the grain! The cycle-friendly towpath winds through the most beautiful valleys in Brittany, from the Aulne to the Erdre, via the Blavet, the Oust and the Vilaine. Connecting several rivers, this canal is a treasure trove of ingenuity and a real technical challenge, with 236 locks punctuating the route used by leisure boats. From Carhaix, we invite you to continue your adventure on the canal as far as Nantes, following the route detailed on the La Vélodyssée itinerary.
