Starting point and access: Saint-Chéron station.
- RER - Line C, on the section between Paris and Dourdan.
Take exit 1 Place de la Gare, on the side of track 2 (direction Dourdan to Paris; if arriving in the opposite direction, take the underground passage).
In addition to the markings, there are numbered markers for the Pays de Limours, indicated here by the initial "B".
Red and white + blue markings
(S/E) On leaving the station, head left, passing a bar on your right, and walk up Avenue de la Gare. At the crossroads, take Ruelle de l'Église à Félix opposite. Ignore the two alleys on the right and take a path that turns right between two walls.
At the end of the path, turn right onto a wide street. After a few metres, climb a stairway path on the left. At a fork, continue straight ahead and ignore the path that branches off to the left. At the end, first turn left then right to follow Chemin des Écoliers, which leads to a road.
(1) Follow the road to the left for a few metres and then turn right onto Rue Henri Louin. At the crossroads, turn left. Ignore a staircase on the right and follow a sunken path below the cemetery. At the end, continue straight ahead between a hedge on your left and a fence on your right. Ignore a path on the right and cross the road again (caution, limited visibility).
Red and yellow markings
Then turn right (leaving theGR®®11straight ahead) and follow the road on its left-hand side with theGRP®® du Hurepoix.
(2) At the oratory, leave the road and follow a grassy path between meadows and fields on the left. At the first crossroads, continue straight ahead along the edge of the woods on your left. At the next crossroads, continue straight ahead and enter the woods. Cross the woods, heading north-north-west, then continue between the fields.
Come out onto the D132 and follow it to the left. After about 50 metres, turn right onto a smaller road towards Ardenelles (spelled without a final "s" on the IGN map). Note a beautiful chestnut tree (partially burnt) on the left-hand side and stay on the tarmac until you reach an intersection (Pays de Limours boundary marker).
Orange + Blue markings
(3) Turn right onto the tarmac road towards Courson and Monteloup (let theGRP®® continue straight ahead). At the next intersection, continue straight ahead on Rue de Vaugirard (sic) and cross the hamlet. Enter the woods and, at the fork that appears immediately (B47-10 Vaugirard), turn left and wind your way through the woods or along the edge.
Yellow markings
(4) At the T-junction (boundary stone), turn left onto a wide paved path. Walk along the right-hand side of the wall of the Château de Bainville park. Enjoy the view of the château through the gate, pass an imposing house on the left-hand side (Maison Neuve on the map) and reach a junction with a road (another view of the château).
(5) Follow the road to the right, preferably on the wider right-hand side, and enter the village of La Tuilerie.
Red and white + orange markings
At the first crossroads, continue straight ahead along Rue de la Rémarde, preferably on the left-hand pavement. At the next crossroads (bus stop), continue straight ahead for a few more metres.
(6) When the street turns right, turn left onto Chemin de Jouy, which starts between two walls. Continue along a fence and enter a wood. At two successive forks, always take the right-hand path.
Red and white + yellow markings
(7) At the next junction, continue straight ahead and walk along a property wall on your right. Climb slightly then descend into a sunken path (carefully cross a few tracks used by mountain bikes). At another junction, continue straight ahead until you reach Route de Saint-Chéron (D116).
(8) Cross the road (take care) and continue straight ahead. At the fork about 50 metres further on, turn right onto Rue de la Tuilerie. Cross Rue Gabriel Péri and continue downhill. At the bottom, turn right and cross the railway line at the level crossing. Ignore a street on the right and then Rue des Douves on the left and cross the Orge river.
(9) At the sign marking the entrance to Breux-Jouy (seen from behind earlier), leave the road and follow a wide path to the right. Facing west-southwest, this path alternates between field edges and undergrowth (note the sound of water falling from an old mill on the right and catch a glimpse of it through the foliage).
No markings
You will come across one or two markers, yellow or red and white, but do not follow a marked route.
(10) Just before reaching the first houses, leave theGR®®, turn right between two small rocks and follow a gravel path. Ignore a path on the right and then one on the left and continue straight ahead on a track between two fences. You will come out onto a street and follow it to the right. At the stop sign, continue to the right and cross the Orge river. At the roundabout immediately ahead, turn left onto Ruelle de l'Orge. At the corner of No. 20, turn right onto a path that climbs towards Saint-Chéron station. At the end, cross a street and you will reach the station (S/E).
