Departure from Bouffémont (Val-d'Oise)
A very beautiful route from station to station in the Montmorency Forest, based in part on four themed trails: “Le Sentier des Lisières”, “Le Sentier de la Reine Hortense” and “Le Chemin des Philosophes” described on the Saint-Leu-la-Forêt tourist information website, plus “Taverny par les Sentes”. Thanks to a number of information boards, the route allows you to trace the region’s ancient and more recent history, admire many of its most interesting sites, and even engage in a bit of philosophy.
It can easily be shortened to 18 km by avoiding the return trip to the Statue of Notre-Dame de France at the start of the walk.
