From Hanches you roll out past the river L'Eure, then on to the castle at Nogent-le-Roi and the watermill at Mormoulins. Next comes the forêt de Rambouillet, a nature reserve, followed by the castle of La Boissière and the Haute Vallée de Chevreuse nature reserve. With 93.4 km of paved riding and 446 m of climbing, you pass the Marais du Cerisaie reserve and the castle of Pinceloup before returning to Hanches.
