Park in the car park of the town hall and church in Morainvilliers, at the end of Rue de la Vallée Maria.
(S/E) Head towards the roundabout you passed when you arrived by car. Then go straight on Rue de la Vallée Maria. Follow this street until you reach Rue des Longs Sillons.
(1) Just after this street, turn right onto the path, which is an old railway line. Follow the first grassy path that veers slightly to the left (Chemin de Poissy) until you come to a path without grass. This path is a doubleGR® trail, theGR®1andGR®26(marked in white and red).
(2) Take this path on the left. Follow it until you reach the road (D113). Cross carefully and continue straight ahead along Rue Sainte-Anne, which passes under the motorway, towards Bures. Continue along this street until you reach the centre of Bures, with the pink "castle" on your left.
(3) At the roundabout, turn right onto Rue du Centre, then right again onto Rue de l'Hermitage.
(4) At the top of the hill, continue straight on Rue de Bures, pass two streets on your left, then turn left after the bus shelter onto Rue de la Clémenterie until you reach the D154.
Cross the road using the pedestrian crossings at the roundabout and continue straight ahead along Rue de la Clémenterie, which becomes Allée du Coteau. You can admire the pretty little valley on your right and the view of La Défense.
(5) At the horse statue, turn left, cross Rue de Breteuil and turn right onto Chemin de la Tuilerie. Leave Chemin du Bosquet on your left.
(6) At the T-junction, turn left onto Chemin de la Côte.
(7) At the next crossroads, turn right onto Chemin du Raidillon (aptly named), which descends towards the centre of Villennes.
(8) Then turn left onto Rue du Maréchal Leclerc.
(9) Turn right onto Rue Michel Giraux.
(10) Turn left onto Avenue du Maréchal Foch. This street becomes Rue de Verdun (there is a logic to this).
After the town hall, turn right to pass in front of a wash house, head towards the railway line and continue to the church. 100 metres after the church is the former home of Émile Zola.
The tour continues by turning left before the church and going up Rue Buquet. At the T-junction, turn right onto Rue Pierre Curie.
(11) Turn into the first street that goes up to the left. Shortly after the bend, turn right onto Chemin des Galères (you couldn't make it up). Stay on the tarmac road, Chemin des Longs Boyaux. This leads to the D154.
(12) Just before the D154, turn left onto Rue des Saules. At the next crossroads, turn right to join the D154. Cross it carefully and continue straight on along Chemin de Marsinval.
(13) At the first bend, you will find a red and white marked path (GR®1) leading off to the left. Take this path and follow the markings until you reach Rue de Brezolles, which joins Rue de l'Ermitage, which you took on the way there.
(4) Cross the street and take the small path that is slightly offset to the left. Do not take the paved street directly opposite, which is a dead end, even for pedestrians.
Go down this path to Rue du Val Joli. Turn right onto this street, which continues as Rue du Chemin Creux, until you reach Rue Sainte-Anne, which you took on the way there.
Follow this street to the right until you reach the centre of Bures.
(3) At the roundabout, unlike on the way there, turn left onto Rue de la Croix de l'Orme. Continue straight ahead, cross the motorway via the bridge and then the D113, and go up Rue de la Vallée Maria to return to the starting point (S/E).
