Continue along the tarred road Route de la Fossette, which enters the forest. You come to a roundabout that you cross to follow Route de la Petite Haie, a forest trail. Then follow Route de la Butte de Montceau until an intersection. Turn left onto Route Cavalière de Guise. At the end, turn right, and at the following crossroads, take the first right. Next, turn left to follow Chemin de Saint-Aubin and cross the D137 secondary road. Continue along Chemin de Saint-Aubin, then cross another very busy road, the old Route de Bourgogne. Continue straight on to the first crossroads and turn left onto Route du Bois Gauthier, then pedal straight on to reach the greenway. Careful, this portion is relatively difficult for the downhill is steep and you must snake your way amongst rocks, roots and sandy areas. When you reach the greenway, turn left. This bike path will take you to the very busy D138.
