Departure from the pretty town of Combourg with its lake and castle, passing through the Chapelle au Filsmen to join the canal towards Dinan, various pretty, well-maintained locks, half-turn to Evran where there is a site for bivouac camping, and a food truck. The ideal is to go to Dinan, a very pretty historic town, you arrive directly at the port with various shops.
