At Vieux-Moulin, park on the side of the road, near the bus stop opposite the lawn, or on the grassy verge of Rue des Étangs de Saint-Pierre.
(S/E) Start the hike by taking Rue des Étangs de Saint-Pierre, heading south-east.
(1) Take the first path on the right into the forest. Continue to Carrefour Saint-Pierre and then Carrefour du Vautrait. Continue straight ahead to reach the small road leading up to the priory. Follow the "Promenade des Moines" signs to the Prieuré du Mont Saint-Pierre.
(2) At the priory, follow the falun path to rejoin the "Promenade des Moines" and follow this direction to enter the forest. At the next signpost, continue to follow the "Promenade des Moines" and, at the next one, leave this path by turning right onto the steep slope. At the bottom of the slope, turn left to reach the Carrefour Notre-Dame-Adam.
(3) At the crossroads, turn right onto the path leading to the Carrefour des Prés de la Ville, then continue straight ahead towards the Carrefour des Prés de Batigny. There, continue straight ahead to join the cycle path and follow it to the left until you reach the crossroads with the departmental road.
(4) Cross the main road carefully, follow the uphill cycle path and then turn left, staying on the path. Pass a small, half-closed path that branches off to the right (marked by an ONF 96 post) and take the next path that climbs to the right and joins theGR® 12 (red and white markings).
(5) Take it to the left, up to the first houses in Pierrefonds, then continue on theGR® 12 to the bottom of the large staircase overlooking the Pierrefonds pond.
(6) At the bottom of the steps, turn left and follow Rue du Beaudon and Rue Jean Lenoir. Cross the D973 at the pedestrian crossing and continue along Rue du Mont Berny and Rue de l'Impératrice Eugénie until you reach the edge of the village.
(8) After the last house, turn right onto the dirt track that leads into the forest, then take the first track on the left, then the first left again to join a large forest road, which you take to the right until you reach the Carrefour de la Gorge du Han.
(9) At the crossroads, turn left to make a round trip to the Étangs de Saint-Pierre and the Pavillon Eugénie, passing in front of the large picnic area.
(10) Return to the Carrefour de la Gorge du Han.
(9) Turn left towards the Carrefour des Étangs junction, then continue left towards the Carrefour de l'Étang de l'Étot junction, then go straight on until you reach the D547 road.
(11) As soon as you reach the road, to avoid walking along the edge of it, take the first dirt track on the right, then the first on the left, then the first on the left. Back on the road, immediately take the path on the right marked by a wooden forest barrier, then turn into the first path on the left to reach the Chêne de l'Auberge.
(12) Head straight ahead to enter the village, walk towards the church, then continue straight ahead to reach the car park (S/E).
