The walk starts from the car park on Rue de l’Église in Saint-Aubin-Épinay, opposite the only shop in the village and near the schools.
(S/E) From the car park, head north towards Franqueville-Saint-Pierre via Rue de l'Église and continue along Côte des Canadiens.
(1) Shortly before the hairpin bend, turn right onto Chemin du Vert Buisson. This road runs alongside two football pitches, which can be seen on the right.
(2) Halfway across the second pitch, turn left onto a path that follows a ravine and climbs up towards the plateau. You are now on theGR®25B. The path climbs for about 1,200 metres through a wood.
(3) At the edge of the woods, you will see the Château du Val aux Daims on your right. Continue straight ahead on the open path for 700 metres. You will arrive at a paved section, which is Rue du Val aux Daims. Turn left onto this street and quickly turn left again onto the Rouges Terres trail, which passes at the foot of a water tower and then arrives at Rue Gabriel Crochet.
(4) Cross this street and continue straight ahead on the path that crosses the fields to arrive near the Franqueville-Saint-Pierre cemetery. Walk along the west side of the cemetery and turn left onto Rue Pierre Curie. Pass the cemetery entrance and continue straight ahead until you reach Rue des Champs Fleuris. Follow it, keeping Rue de la Bergerie on your right.
(5) 50 metres after Rue de la Bergerie, turn left onto a path that leads into the fields. You are now on theGR®25. The path descends and arrives at a crossroads.
(6) At this crossroads, continue straight ahead even if the path is not very clear. After 300m, you will find a bench where you can rest. Continuing on, the path takes you close to the Bel Évent farm.
(7) At the fork, turn left and descend alongside the pastures. You will pass a pond on your left, which is dry in summer. Continue along this path, which descends to the edge of the woods and leads to the D91 road at Le Faulx.
Turn left to descend the Route du Faulx and, at the bottom, turn left to follow the Route de Lyons-la-Forêt D42, first on the pavement and then on a path for cyclists and pedestrians.
Follow this flat path for 1,800 metres, passing the Chemin des Hauts Bœufs and the Chemin du Château on your left. When you reach Saint-Aubin-Épinay, this path is called the Sente de la Ravine.
(8) Turn left onto Chemin de la Source. The path is paved and lined with houses. Follow it to reach the source of the Aubette. After reading the information panel, continue to the end of the paved path.
(9) Go up into the woods on the dirt track that branches off to the right. Continue until you reach a clearing.
(10) Take the path on the right that descends gently to reach the Moulin path (tarmac).
(11) Turn right to descend this road and return to the car park (S/E).
