Description of the walk

Departure from Saint-Denis Church in Jouy-le-Comte. Parking is available in one of the three small car parks located on Rue du Maréchal Joffre, two south of the church at the intersection with Sentier du Ru de Jouy, and one north just behind the church.

No signposts

(S/E) Facing the church and the school, take Rue des Maillets towards the Jouy-le-Comte cemetery (sign). At the fork at No. 5bis, turn left into the lane that goes uphill. After a bend to the right, pass the entrance to a private property on your right (signs warning against trespassing) and continue straight ahead along a sunken path. You will come out onto the plateau.

(1) At the junction with theGR®1(no signpost here due to lack of support), continue straight ahead (west) along a path between the fields that gradually curves to the left (south-west). At the next junction, level with a copse on your left, turn right towards another copse. After passing this copse (on your right), you will reach the Croix des Friches (stone cross).

Yellow markings

(2) Continue in the same direction (north-west). Enter the woods and find the first yellow marker. Descend along a sunken path with a fence on your left. Cross a track and continue downhill. You will come out onto a small road (stone cross).

Yellow + red and white signpost

(3) Follow the small road on the right. At a private property on the right, the road gives way to a path between two hedges. Shortly after the junction with a path coming from the left, turn right at the corner of a field. Enter a wood, turn left and climb gently through the undergrowth. Pass a path coming from the right and reach a crossroads.

No signposts

(4) Leave thePR® andGR® markings on your right and continue straight ahead (north) on a small road which further on gives way to a wide gravel path between private property fences.

(5) At the junction with Chemin des Moutons, continue north-west towards Nesles-la-Vallée (sign at the corner, look behind you to find the inscription "Nesles-la-Vallée"). Come out between fields, pass under the high-voltage lines and enter the woods again.

Yellow markings

(6) At the next crossroads, turn right and follow the signs for "Polissoir" (sign). Go straight ahead into the forest for about 300m. At the crossroads, turn left and head north (another yellow sign continues straight ahead; there is an explanatory diagram just before the crossroads, follow the signs for paths - CH - nos. 1, 5 and 7). At the next crossroads (red marker indicating an underground oil pipeline), leave the yellow signs for a moment and turn right into the wide lane. Look for a sign for "Polissoir" high up on a birch tree on the left: make your way through the ferns to quickly reach the polissoir (information sign).

(7) Retrace your steps and turn left into the wide lane. At the next junction (red marker), turn right and follow the yellow markers. At the next junction, continue straight ahead (yellow marker "CH3") and go down the gentle slope. At the T-junction, turn left onto Chemin Rural du Bois Brulé (sign).

(8) At the crossroads, turn right, go past a forest barrier and continue along the edge of the woods on your left and the field on your right. At the corner of the woods, continue straight ahead and pass under the high-voltage power lines. Walk between the fields and then along the edge of the copses on your left.

(9) Before reaching Chemin des Moutons (sign), leave the yellow markings for a moment and turn left onto a wide path at the edge of a small wasteland; at the end, turn left and follow the yellow markings (marker post on the right). Further on, take a hairpin bend to the right (gate in the hollow of the bend) and descend onto a small road.

Without markings

(10) At the crossroads, ignore the yellow markings and turn right into Rue du Maréchal Joffre. Walk alongside a horse pasture on your left and note the beautiful farmhouse and dovecote behind it. Follow the street south-southeast, ignoring the perpendicular lanes. At the stop sign, continue straight ahead, still on Rue du Maréchal Joffre, and climb gently towards the church, whose bell tower is clearly visible. At the corner of the small car park just before the church, you can make a quick detour to see a wash house located at the bottom of the path that branches off to the left (chicane). Then return to the church (S/E).

Notes

Good walking shoes required. No water points listed.

Recommendations for the route in the Forêt de la Tour du Lay:
- During the season (September-February), avoid Mondays, which are hunting days.
- SeveralPR® trails, all marked in yellow, intersect in the forest. Therefore, do not focus on the markings but follow the map and description carefully.

You can start from the Isle-Adam-Parmain station:
To get there by public transport, get off at the Isle-Adam-Parmain station (Transilien line H, on the section between Paris-Nord and Persan-Beaumont via Montsoult-Maffliers). There are several ways to reach the route; below are two suggestions for the outward and return journeys respectively.
- Outward journey - Turn left when you leave the station. At the next crossroads (bridge over the Oise on your left), turn right into Rue Guichard. Then take the first right, Rue du Maréchal Foch, then the first left, Chemin de Montarène. After a left turn, take a sharp right turn onto a path, then turn left to reach the plateau. Continue north-west (path marked in purple on the map), pass the 105 metre elevation point and rejoin the main route at the 87 metre elevation point (grove).
- Return - At the point (9), continue straight ahead. At the crossroads with Chemin des Moutons (sign), continue south on Chemin de Méru. Near the point (4), join theGR®1and continue south. Pass the point (1) and continue south-west on theGR®1. Come out onto Rue du Maréchal Foch, follow it to the right, then turn left towards the bridge over the Oise and left before the bridge to reach the station.

A 1:25,000 map is required (at least the one accompanying this description).

Hike completed by the author on 14 November 2015.

Worth a visit

- Saint-Denis Church (11th-19th centuries) in Jouy-le-Comte (S/E).
- Croix des Friches (2): stone cross dating from the Middle Ages, which marked the boundary between the communes of Parmain and Nesles-la-Vallée.
- Tour du Lay departmental forest between (6) and (8): forest with some remarkable trees (beech, oak) and beautiful fern undergrowth.
- Neolithic polishing stone (7).
- Dovecote shortly after (10).

Between points (4) and (5), the map indicates a hypogeum called Le Trou à Morts. Unfortunately, this ancient megalithic burial site is not accessible as it is located on private property surrounded by a fence.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

We modified the route to start and finish at L'isle Adam train station. A very pleasant autumn hike. The map is well designed and allowed us to modify the itinerary.

Hello,
Thank you to Visorando for the selection, quality and accuracy of the walking routes on offer. It's a real treasure trove, with a wealth of choice, and I would highly recommend it.
We set off yesterday to explore the "La Croix des Friches and the Tour du Lac forest" walk.
Between the start and point 2, there were no problems. But from point 2 onwards, there was a change of plan: the path was downhill and recently and deeply eroded (by recent rain?), the woods were in a terrible state (with lots of fallen trees everywhere), and we ended up at the Ormeteau woods with a large tree blocking the path.
This bad impression made us abandon the walk.

A hike with no particular difficulties or breathtaking scenery.
The polishing stone is worth a detour for its archaeological interest.
Be careful, as this area can be quite windy between 1 and 2 in the cold seasons

Good description of the route.
Some interesting sights, such as the Friches cross and the curious polisher, which we never imagined could exist, proving that our distant ancestors were very resourceful.

hello, beautiful hike through woods and fields. Apart from a slightly steep start, it was easy overall. We only encountered four people during the two-and-a-half-hour walk. Note that the end of the hike is in town.

A very beautiful hike, alternating between fields and woods, particularly pleasant on a sunny day. The description is perfect and very accurate. There was just one moment of uncertainty at number 6, where it says "at the crossroads, turn left and head north", but after a bit of trial and error, it turned out that we had to turn right (but perhaps we missed a landmark in the description earlier).

A pleasant, easy hike, much of it through the woods, but good footwear is recommended as some sections are technical and slippery when wet.
