Rondje Château du Haut-Rosay en La Mauldre

The ride

Roll out of La Queue-les-Yvelines and the Haute Vallée de Chevreuse nature reserve opens the ride, before the Forêt des Quatre Piliers takes over. Then come the castles: Septeuil, Haut-Rosay and Beynes, one after another. The Mauldre river and the Commanderie des Templiers de La Villedieu lead you on toward the étangs et rigoles d'Yveline nature reserve. All 75.9 km are paved, and the route brings you back to where you started.
