Departure
Car park at Maffliers church. You can get there by car or public transport. Montsoult-Maffliers station is about 1.5 km away. On weekdays only, a bus connects the station to the centre of Maffliers (https://www.cars-lacroix.fr/mobilite-urb...).
PR® (yellow) trail markers
Take Rue du Bois Carreau, then at No. 19, turn left onto the path that goes downhill.
When you reach a wider track, turn left, then continue straight ahead and leave thePR® trail, which turns right, a few metres further on.
No markings
(1) Continue straight ahead on the path, which is no longer marked. It winds its way between a field on the left and a wood on the right. You will come to the edge of a field, which you must cross, following in the footsteps of previous hikers to reach the farm track slightly to your right.
PR® markings (yellow)
(2) Turn left and continue to the D64 departmental road at the entrance to Nerville-la-Forêt.
GR® markings (red and white)
(3) Turn left and, a few metres further on, take the path that climbs up to your right. You will pass close to an underground reservoir and turn left to reach a forest road, which you take to the right.
(4) At the crossroads (Poteau de la Tour), take the clay road to the Porte Baillet crossroads.
(5) Cross the N184 bridge and continue along the forest road. Pass the Chêne au Loup crossroads and arrive at the Vicaire crossroads.
Take the second path on the left and continue until you reach the large fence wall of the Parc de l'Abbaye du Val. Turn right.
(6) When you reach the crossroads at the corner of the wall, turn left onto the second path.
This path winds along the upper edge of old quarries. A wooden balustrade has been placed at the edge of the cliff to prevent accidents.
Continue until theGR® turns 90° to the right.
No markings
(7) Leave theGR® on your right and continue straight ahead for about 100 metres, then turn left onto the path that descends.
Pass under a ruined bridge arch and cross the protected wetland area of the Marais de Stors.
(8) At the crossroads, turn left onto the sunken path that climbs slightly. Continue to the boundary wall of Abbaye du Val, turn right, then left and follow this wall to the large entrance gate of the abbey.
(9) Cross the D9 road and, opposite, go up the path to the barrier that closes off Rue du Pavillon de Chasse de Mériel. Follow this street to the end of the cul-de-sac. A pedestrian crossing takes you to the N184 bridge.
(10) Cross the bridge and enter Villiers-Adam via the D1. A few metres further on, continue left along Rue de Mériel and then Rue Patouillard Demoriane.
(11) At No. 31bis, turn left onto Chemin de Stors.
At the crossroads, turn right, then 200 metres further on, turn left to go alongside a farm and continue across the fields to a farm track running parallel to the N104. Turn right, go through the barrier and turn left onto the bridge to cross the N104.
Continue until you reach the bridge on the N184.
GR® markings (red and white)
(12) Turn right onto the farm track closed by a barrier and immediately left onto the path that enters the forest. Continue to the edge of the forest in a hollow.
PR® markings (yellow)
(13) Leave theGR® markings and follow the path that branches off to the left.
A little further on, the path turns right, crosses a large field and turns left to reach a tarmac road.
(14) Cross the tarmac road and continue straight ahead for about 200 metres, then turn right.
The path winds through the forest for about two kilometres to reach the Carrefour Boucault car park.
(15) Take Route Boucault, then turn right at the first crossroads onto Route du Tourniquet de Montsoult.
At the next crossroads, turn left onto Route de la Tente between forest plots 50 and 55. At Route des Deux Châteaux (crossroads located at the junction of plots 51, 52, 53 and 54), do not follow thePR® which turns left: thePR® route has been changed, so follow the description rather than the map.
No markings
(16) Turn right between plots 53 and 54 and continue to a large ruined fence wall, of which only a large metal gate remains. Go around this gate on the right and follow the path that veers left in the middle of a grove of tall rhododendrons (4 to 5 metres high) to reach a track where you turn right.
At the end of this track, cross the Maffliers equestrian centre, pass in front of the château and the Novotel and continue to the large wrought iron gate, which is always open.
PR® (yellow) markings
(17) Turn left onto the path that goes downhill (Rue de la Ferme), which becomes tarmac at the bottom of the descent.
Follow it to the end, cross the crossroads and turn right into Rue de la Forêt, then left into Rue de la Mairie to return to the church car park (S/E).
