Description of the walk

Start of Rue Moreau (see parking conditions in the practical information section).

No signposts

(S) Go up Rue Moreau, keeping Rue aux Chevreuils on your right.

(1) At the fork, take Rue de la Muette on the right. Continue along the tarmac road, which quickly turns into a dirt track. In the left-hand bend that follows, you can admire the view of the Mauldre valley and the town of Beynes before starting a gentle descent.

(2) At the right-hand bend, take the path protected by a forest barrier (no horse riding sign). Ignore the path that branches off to the right and continue straight ahead, climbing slightly before arriving at a slight incline that leads to a paved road. Follow this road to the right (west) until you reach the Grande Table crossroads.

(3) Take the Chemin des Mares (3rd on the left) and follow theGR®11. Pass a first gas storage platform that quickly appears on your right, followed by a second one on your left. At the next crossroads, continue along the tarmac road that branches off to the right. Then start descending until you reach a metal forest barrier at the junction with the C3 municipal road.

(4) Cross the municipal road (watch out for traffic!) and then go up the grassy path opposite (sign CT069). At the top of the hill, pass the gas installation on your right and take the path that branches off to the right. Back on a tarmac road, turn left to reach the Petite Table crossroads.

(5) Cross the crossroads and continue west on Route d'Auteuil to the left of the sign marked VA150. Continue straight ahead until you reach another gas installation on your right. Continue west between forest plots no. 9 on your right and no. 11 on your left.

No signposts

(6) At a junction with a path crossing perpendicularly (white GDF post), leave theGR®11and take a path on the left, entering forest plot no. 11 (signposted "piste cavalière"). Then go through a forest gate and continue straight ahead with a field on your right and a forest edge that will then give way to a field on your left. Go under a high-voltage line and then cross the Route de Versailles (D11: watch out for traffic!). Enter Saulx-Marchais via Rue de l'Église.

(7) Pass the church of Saulx-Marchais and its cemetery set back from the road to reach a crossroads with the village hall. Turn left into Rue de la Mairie, pass the town hall and then the school. Then turn right into Chemin des Sablons. Continue straight ahead until the asphalt gives way to a dirt track between fields and meadows.

(8) At the bottom of the slight descent, turn left (south-east) onto Rue de la Treille until you reach the entrance to the hamlet of Basse Pissote. Continue straight ahead on Chemin de Paris (a dirt track that will take you away from the houses and continue between the fields.

Shortly after a yellow GRDF sign in the shape of a house roof (underground gas pipe), you will come to a three-way junction (elevation 93). Continue left on the path between the fields and go straight ahead until you reach the Route de Versailles (D11).

(9) Cross the Route de Versailles (watch out for traffic!) and continue between the fields. Ignore the junction with another path and continue straight ahead until you reach the houses in Cressay. Pass a house decorated with painted tiles and continue to Place des Tilleuls. Then leave the square via Rue de Beynes on the left (dead end).

Chemin de Grande Randonnée - White and red markings

(10) Join theGR®11and continue straight ahead until you reach a farm. Cross the farm, continuing straight ahead, then follow the path with horse paddocks on your right and the edge of the forest on your left.

(11) After passing another gas plant on your left, enter the undergrowth via the path that branches off to the left (north-west). Follow the path, which then begins a fairly steep climb. After a right-hand bend, you will come to a forest gate.

Green and yellow markings

(12) Cross the paved road, leave theGR® and take a path that branches off to the right. Continue straight ahead until you reach a forest gate that opens onto a paved road. Take this quiet road to the left (north-northeast) to return to the fork you took at the start of the hike.

(1) Continue straight ahead on Rue Moreau until you reach the starting point (S/E).

A varied hike with no particular difficulties, bucolic, combining forest, fields and small villages in almost equal proportions.

Please note that this hike can easily be done from Beynes station by adding 15 minutes each way along the Mauldre river (turn left after the wash house bridge at the station and continue to the Beynes pond, then go back up Rue de l'Étang)

Do not do this hike after a period of rain as the paths are very muddy.
Do not do this on Mondays due to hunting.

Completed with a GPX file, so no comments on the instructions.

A pleasant hike with varied landscapes. I started from Beynes station, which is just under 15 minutes from the station to the start/finish point, and it gave me the opportunity to see Beynes Castle and its church.
Probably best avoided in wet weather (forest + fields) and very hot weather, as there is a fairly long stretch straight across fields with no shade on the way back — I wasn't hot, but I wondered if I should have put on some sunscreen. At point (2), there is only one post left on the left as a trace of the forest barrier, but the path is still clearly visible.
The forest is beautiful at this time of year, and will no doubt be even more so in the coming weeks, as it was still quite green on 11 November, but I saw some posters about anti-hunting activities this winter in the Beynes national forest, on Mondays from 9 a.m. to 6 p.m.:
- monday 21st and 28th November
- monday 5, 12, 19 and 26 December
- monday 2, 9, 16, 23 and 30 January
- monday 6, 13, 20 and 27 February.
Thank you for this journey!

A varied route in terms of landscape: plains, fields, forest and a little bit of town.
We parked in the car park near the town hall without any problems. The wash house in Cressay is definitely worth a visit. We simply walked back up the small road to rejoin the route. Thank you

Thank you for this beautiful hike, with a good balance between woods and fields.
You can easily picnic on the grassy path behind the Saulx Marchais school (benches and low walls) or in the forest (benches at major crossroads).

A pleasant and varied route through forests, fields and villages.
Please note that some sections are muddy, particularly in areas where forestry work is being carried out.
The wash house in Cressay, as mentioned below by Patricia, is well worth a visit.

A very varied route through woods and countryside, quite muddy at this time of year. There was a slight doubt in the description at the start, at point 1, where a dirt track starts opposite the first bend, but you have to keep going along the road, which was clear from the map. That'll teach us to rush off without looking! The storage areas and pavilions are not particularly memorable, but once again, thank you to Netra for his perfect routes.

A pleasant route with the discovery of a special forest with reserves and a beautiful valley
The best place to start is at the castle, where there is free parking and you can see this monument

i forgot to mention one small detail in my previous comment.

In point 5, follow Netra's description, which is perfect. The directions for the Auteuil road on the small table send you slightly to the left of the road you should take.

i really enjoyed this tour, which I was able to do on a sunny day. No navigation issues, just follow the description and you're good to go.
I wondered why there were so many gas storage areas in this beautiful forest and how they worked
I was lucky enough to meet some of the staff who manage the storage facilities. One very friendly member of staff took the time to explain everything to me from start to finish.

Thank you, Netra, for this great tour.
