The circuit crosses a woodland and hilly area where many streams flow and the canal of the pond of Boulet that fed the canal of Ille-et-Rance. It runs along the latter for 2 kilometers by taking the green road that borders it (V2). It takes the bike route from Saint-Pern to Antrain (VD4) to the north between the villages of Montreuil-sur-Ille and Feins with the exception of a small section that allows the circuit to run along the edges of the Boulet pond. A departure is possible in each commune crossed by the circuit - Tour Bike Sheet® available in Tourist Offices and Town Halls: Free
