Description of the walk

Park in the car park of the Orme au Berger cemetery, located near Magny-Village, on the other side of the D195 from the village.

Yellow markings

(S/E) Continue along the road away from the D195. At the end, go through a metal gate and follow a grassy path between the fields.

No markings

Atthe first crossroads (elevation 169, isolated tree on the left), turn left. Walk eastwards between the fields. Pass the equestrian centre facilities and return to the tarmac road.

(1) At the T-junction, turn right onto Rue Raymond Bonheur, which soon becomes Chemin Rural n°17 (a small gravel road). At the end (elevation 162), turn left. Walk along a wood on your right, then between the fields. Enter a wood, turn right with the path and you will immediately come to a T-junction.

Red and green markings no. 6 (very rare)

(2) Then follow a wide forest path to the left. Ignore a path on the right, turn left with the main path and walk along the woods on your left. Continue straight ahead, pass a forest barrier and you will soon reach the tarmac road. At a small roundabout (beautiful old farmhouse on the left), turn right towards Magny-centre-bourg.

(3) Go around the next roundabout on the left, cross the D195 at the pedestrian crossing and follow it to the left, taking a small paved path that runs parallel to it. Ignore any paths branching off to the right. When you return to the D195, turn right onto Chemin Rural n°30. Continue straight ahead. After a forest barrier, the tarmac gives way to a path that descends slightly.

No markings

(4) At an intersection, turn left towards Magny-Village. Pass a small building on the right and follow a wide path that winds between meadows.

(5) At a crossroads, take thesecond right, the Route forestière de Mérancy, still heading towards Magny-Village. After about 300 m, follow the cycle signs on the right (leaving the direction of Magny-Village).

(6) At the crossroads after about 100 metres, take a path on the left and follow the Mérantaise river on your right (do not cross the river). Wind your way through the undergrowth. Note the reed bed on the left and the sandstone rocks on the slope of the opposite bank.

Red and green + yellow markings

(7) At a small stone bridge, continue straight ahead, keeping the river on your right.

Red and green markings no. 7 (rare)

At the next junction, turn right and cross the river. The path immediately turns left and winds through the undergrowth. Pass a spring (small masonry structure) on the left, exit the woods and reach the Mérantaise forest house.

(8) Then descend to the left along a wide stony path. Just before a small bridge, turn right, pass a wash house and follow the river on your left. At the wall, ignore a path on the right and continue along the river. At the next junction, turn left towards Magny-Village and cross the river via a footbridge.

No markings

A few dozen metres further on, turn right onto Chemin Rural n°2.

(9) About 150 metres later, take a sharp right onto a path that descends (do not follow Chemin Rural n°24 to the left). Cross the river again and pass between a spring on the left and an old wash house on the right. At the T-junction, turn left. Stay on the main path, ignoring all the side paths, and alternate between short ascents and descents. Walk along the left-hand side of the Mérantaise, which is now just a trickle of water, then a fenced-off pond. At a fork, turn left, go uphill, pass a forest barrier and you will come to a road.

(10) Follow the road to the left and downhill, initially on the well-defined left-hand shoulder. At the entrance to the pond, move over to the right-hand shoulder, which is more convenient and offers better visibility. Then stay behind the safety barrier on a narrow grassy path with a slight slope. After the sign marking the entrance to Magny-les-Hameaux, turn right onto Rue Paul et Jeanne Weiss. Go uphill, enter Brouessy and turn right with the road.

(11) When you reach a large house on the right-hand side, turn left onto Allée des Pommiers (dead end). Go through a chicane and continue along this small tarmac road. When you reach the D195, turn left onto this road. At the crossroads (chicane), continue straight on Rue Eugène Carrière. Then take thefirst right, Rue Ernest Chausson.

Yellow markings

Ignore the street coming from the left and immediately cross the D195 at the pedestrian crossing. Opposite, slightly to the right, take Allée de l'Orme au Berger. Continue straight ahead to the cemetery car park (S/E).

Notes

In dry weather, good trainers may be sufficient for this route, which follows well-maintained paths and small tarmac roads. In wet weather, hiking boots may be useful, especially between (6) and (10).

No water sources were identified along the route.

Variations:
If you wish to shorten the hike, from the Mérantaise valley, it is possible to return to the village of Magny at several points:
- After the forest house (8), cross the river and turn right at the various intersections.
- Between (8) and (9), after crossing the Mérantaise on a footbridge, continue straight ahead following the red and green markings (do not follow CR No. 2).
- At (9), follow CR No. 24 to the left.
In all cases, when you reach Saint-Germain Church, follow Rue Ernest Chausson (yellow markings). Continue straight ahead until you reach the D195, cross at the pedestrian crossing and continue straight ahead to the cemetery (S/E).

A detailed map is required (at least the one accompanying this description).

The first part was difficult to walk on, as the paths through the fields were completely ploughed and very muddy. The rest of the hike in the forest was very good.

The first part of the hike across fields, the trail has been badly damaged by work to bury power lines. If you do this walk in summer, set off early as there is no shade on this section.
Next, you cross a hamlet and the forest, then return to Magny, which is not a very pleasant area. You then reach some very pleasant and varied paths from the descent towards La Mérantaise. Here, you enter the forest, and this valley used to be truly enchanting, but since last winter, many trees have fallen, giving it a somewhat devastated appearance.
The description is very reliable, and there are no problems with the route, but you sometimes have to climb over fallen trees.
However, most of the obstacles have been cleared.
We follow the Mérantaise to the exit onto the road.
The end of the route on tarmac is dangerous and sometimes there is no room to avoid the cars, which drive quite fast.

Hike following on from the one entitled "La Forêt de la Madeleine and Port Royal Abbey" on a mild but grey day.
There were significant difficulties along the Mérantaise. Although fallen trees had been cleared at the start of the trail, several remained further along that were not easy to get past, particularly on the bridge between points 6 and 7, where two trees were lying across the path. To cross, you had to climb over them or even put a foot on the parapet. It was doable but quite acrobatic.
I understand the reference to a chainsaw made by a previous commenter.
I would have posted a photo of the place, but my camera broke down right at the start.
The passage behind the safety barrier at the end of the route is not easy, but you are protected from traffic.

Beautiful hike
Two drawbacks
Between 4 and 5 Way point, constant aircraft traffic
The end of the trail on a road that is not really safe

The route is pleasant, but there are far too many planes flying overhead... enjoy the peace and quiet.

Halfway along the route, you have to use a chainsaw to cut down fallen trees.

The end of the bitumen road is dangerous with cars speeding by!

Start across the fields: set off early to avoid the heat at this time of year.
Small village, forest, very pleasant and varied paths.
Very reliable description, no worries about the route.
One small downside: lots of small planes, so there are few moments of silence.

Nice route, but constantly accompanied by aircraft noise. Perhaps it would be better to do this route at dawn.

A varied hike in good weather. The last kilometre on tarmac is not pleasant.
But I recommend it.

A very pleasant walk between fields and forest. The description is clear. We saw grey herons, egrets, chiffchaffs, etc.
I recommend it.
