Description of the walk

Departure from the car park at Place du Château in Aigremont.

(S/E) Go to the back of the car park and climb up into the forest via the flight of steps on the left. Climb briefly up a steep path and, at the T-junction, turn right.

(1) At the next crossroads, turn right onto a path alongside a wire fence. Ignore the path on the left. At the T-junction (elevation 153), take the path on the left.

(2) Just before reaching the D30, follow the wide path on the left to a crossroads where there is a sign saying 'Partageons nos espaces naturels' (Let's share our natural spaces). Take the first path on the right heading south-west; thefirst path on the right on the map, heading west, does not exist.

(3) At the T-junction, turn left. At the fork, take the path on the right. After about 100 metres, turn left. Continue along the path that winds along the edge of the slope. Ignore the paths on the left and right. Note the beautiful view of the ponds at Joyenval golf course. The path eventually descends along a wire fence towards a road.

(4) Cross Allée Frédéric Passy to take the path opposite (yellow markings). Walk along the Joyenval golf course on your right, then along the Ru de Buzot. Find a small road and follow it as it continues. At the next intersection (barrier on the right), go straight ahead and continue along the stream on Chemin de la Tuilerie in Fourqueux.

(5) At the next intersection, continue straight ahead with aGRP® (red and yellow markings). After a bench, turn left, cross the stream and take a concrete path uphill. At the end, first turn left then right to follow Rue de Montaigu.

(6) Take thefirst left, the Sente des Acacias, and go uphill. At the top, turn left. After about 150 metres, take the Sente du Cimetière on the right.

(7) At the end, before the school, take a path on the left (yellow markings) leaving the GRP®. At the end, first turn left then right and take the Sente du Bois Barbeau. Ignore a path coming from the left and continue to a street.

(8) Follow the street to the right. At the immediate crossroads, turn left onto Chemin des Alluets. At the next crossroads, continue straight ahead on a path that enters the forest and leave the yellow markings on the left.

(9) After about 300 m, take a path on the right that quickly branches off to the left. At the next crossroads, go straight ahead.

(10) At the T-junction (the path opposite does not exist), turn right and go downhill.

(1) At the junction you took on the way out, continue straight ahead. You will come out onto Grande Rue; follow it to the left. After about 50 metres, you will find the car park where you started on your left (S/E).

Notes

No special equipment required.

Worth a visit

Near point (2), 200 metres away, is the Désert de Retz, a folly worth visiting. Reservations can be made on the Chambourcy town hall website.

A few metres from the finish line, take the lane leading to the wash house to admire it.

A very attractive route offering a good balance between woods, nature, streams and a more urban environment. Very interesting historical remains from the Tailles d'Herblay resistance centre during the First World War, immediately after point 2. Too many fallen trees between points 9 and 10. We abandoned this small path in favour of the main paths, passing through the central point (altitude 162) and returning to point 10 and our starting point.

We set off near point 7, where parking is easy in front of Chambourcy Cemetery.
On these beautiful days in early April, the trail was not too muddy.
About 300 metres after the D30 (which we did not take), there is a discovery trail on the right explaining the traces of a resistance centre from the 1914-1918 war: |https://www.destination-yvelines.fr/randos-a-pied/parcours-decouverte-du-centre-de-resistance-de-la-premiere-guerre-mondiale-en-foret-departementale-des-tailles-dherbelay/]
A pleasant return trip along the Ru de Buzot. Thank you to the author for this lovely walk

The GPX track was a great help in some places to ensure we were following the route correctly, as the description is unfortunately insufficient. The hike is still very pleasant and offers beautiful views: I would still recommend it for experienced hikers, especially at this time of year, as some parts were very muddy or even flooded.

A very pleasant and varied route. A little too much forest for me. Some beautiful properties just a few kilometres from Poissy and its urbanisation
Very nice

We go hiking once a week on Mondays, when there are few other hikers around.
A pleasant hike through woods and hills along the Gulf of Joyenval and the heights of Chambourcy.
To be repeated in the spring.
Best regards, Claude

Hello, I had a bit of trouble at the start and finish. In my opinion, the information for returning to point 9 was not clear enough at the fork in the road (and was also hidden on the map by the large "9" marker)
But the route was great, beautiful and otherwise very well marked
thanks to the author

Superb hike with a few climbs and some very muddy sections, but also very pretty views of Joyenval golf course and a very pleasant path along a small stream. We encountered a few groups of mountain bikers. Worth doing again when the vegetation has grown back.

The small path that starts at point 10 and leads to point 1 on the map is impassable due to fallen trees
Paths transformed into lakes at the start and end of the hike

A pleasant route, best done in summer, as in February the area is very muddy and slippery (between points 1 and 3, wear boots). The description is accurate, but you need to be careful. There was not a soul on the route, yet this walk is well worth the detour. Worth doing again.

A beautiful hike and a wonderful discovery! There were a few mountain bikers (it was late Sunday morning) on the trail after (3), but they were courteous and respectful, so no problem. There was just one very slippery section at the start of (4) due to a wet May, but it was only about 2 metres that were really tricky. The section along the motorway is short and doesn't spoil the good time had. Thank you to the person who discovered/described this route!
