The start of this circular route is located in a car park at the exit of the hamlet of Les Christophes (municipality of Sorel Moussel), at the intersection of Route des Glands (D301.14) and Route de Marcilly-sur-Eure (D21.7).
(S/E) The path starts in the car park and heads north-west. This is the Route de la Messe, which once allowed the inhabitants of the hamlet of Les Christophes to go to mass at the Church of Saint-Nicolas-de-Sorel.
Follow the Route de la Messe for about 600 metres, passing the first two driveways and then two paths on the right, until you reach a four-way crossroads. Leave the Route de la Messe by turning left onto the Route des Rousseaux. Continue straight ahead for 500 metres, passing a driveway on the right.
(1) At the four-way crossroads, turn right and head towards Château de Sorel.
(2) In front of the castle gate, continue along the right-hand side of the carriage road that descends towards the village of Sorel.
(3) At the edge of the forest, take the small path on the left, passing between the gardens near the church. Follow this path, which will take you to the church square, then take Rue de l'Église and continue down the street to the main road. Turn right, then after about 50 metres, turn left onto Rue du Pont Coupé and cross the bridge over the Eure.
(4) Cross the bridge and try to locate the Gravier de Gargantua. Then continue along the path to join the greenway at Buisson de Croth. Follow it to the left and continue to Marcilly-sur-Eure. At Route d'Ezy, continue straight ahead, walk along the back of the village, cross a small road and come out onto a road at the corner of No. 14 on your right.
(5) When you reach this crossroads, you can take a break in the town centre, 200 metres to your left, where you will find a bar, restaurant, chemist, bakery and crêperie. Visit the church...
After your break, continue along the greenway, cross a street and continue for about 400 m until you reach the first road intersection after passing the old Marcilly train station. Note the presence of an electrical transformer station on your right.
(6) Turn left and, at the Dreux road, cross over to take a rural path opposite, which starts to the right of No. 63. A little further on, this path runs alongside two streams (Bras du Couesnon... a small tributary of the Eure that crosses the town of Dreux).
Continue until you reach this small branch of the river and a small crossroad.
(7) Turn left, continue for about 60 metres, then turn left at the corner of No. 10. Cross the small bridge over the Couesnon, then turn right to return to the road.
(8) Turn right, cross the bridge over the Couesnon and then the bridge over the Eure, and you will soon reach a four-way crossroads.
(9) Turn right onto the D116 towards Montreuil, continue for about 30 metres and you will find the entrance to a forest path on the left. Leave the road and take the path, climbing up to the plateau (40 m elevation gain). Continue along the path and join the Route de la Ferme Brûlée, following it straight ahead for about 1 km until you reach a four-way crossroads.
(10) Turn left onto a wide path and join Route de Marcilly. Cross this road and continue for about 100 metres until you reach the next crossroads. Turn right onto Route Forestière d'Harrouard, then continue along the departmental road and you will soon reach the car park (S/E).
