Located in Brittany, in the Ille-et-Vilaine department, this greenway follows the old Duchess Anne dike, which once protected the plain from the sea. Between La Chapelle Ste Anne and Le Pas au Boeuf, it offers an 11 km route. The surface is stabilized and suitable for mountain biking, horseback riding, and walking. Its winding path through the polders allows you to glimpse Mont Saint-Michel on a clear day. Along the route, at Quatre Salines, you can discover the "Maison des Polders" (Polders House), housed in a beautiful 17th-century building.
