Loop in the Ferrières and Armanvilliers forests

The forests of Ferrières and Armainvilliers are contiguous over a very long stretch from east to west. They form the largest wooded area in eastern Paris. It is a single humid forest with very little relief, dotted with ponds. It is renowned for mushroom picking. This hike allows you to discover the tree species that make up the forest: oak (sessile and pedunculate), ash, lime, maple, cherry, service, etc.

Description of the walk

Preliminary note
There have recently been changes to the signposting in this forest.
If there is a discrepancy between the signs you see on site and those indicated on the IGN map, please follow the description as the map has not yet been updated.

Start
The hike starts at the car park of the Pontcarré Town Hall.

(S/E) Take the Grande Rue on the left and, before the church, turn right onto Chemin de la Cendre. This road runs alongside the square and then takes a very narrow passage between a masonry wall on the left and a hedge on the right. It joins a wider path bordered by a wall on the left and marked GR®.

GR® markings (red and white)
(1) Turn right onto this path and a little further on you will pass under the D471. Continue and, at the crossroads, turn left onto Route de la Guillaumetterie; the path continues along a wall until you reach the Carrefour de la Grille de la Planchette, in the centre of which stands a signpost.

(2) Take Route de la Planchette (GR®14) on your right and continue to the next signpost.

(3) Turn right again to follow Route de la Croisette.

(4) At the Carrefour du Chenot, turn left onto the Route Forestière de la Barrière Noire and continue until you reach the second crossroads.

(5) Turn right onto a very wide grassy track about ten metres wide that takes you to the Carrefour des Trois Mares.

(6) Continue left on the paved road for about 200 metres, then turn left onto the path that winds for about one kilometre before joining a forest road at the Carrefour des Étangs, where theGR® trail branches off to the left.

No signposts
(7) Turn right. After about one kilometre, you will cross the D471. Continue straight ahead for another kilometre and you will arrive next to Ozoir-la-Ferrière station. Turn right and continue to the entrance of the passage under the railway line without crossing it.

PR® signposting (yellow)
(8) Cross the concrete bridge over the stream and turn right onto the path that leads away from the railway line. It crosses the Route Forestière des Charbonniers at the forest plot marker 37, where you will find theGR® signposting.

GR® signpost (red and white)
(9) Turn left onto this forest road. Cross the Carrefour du Sanglier, then the Carrefour des Usuelles, and at the next crossroads you will find a signpost in the centre.

(10) Turn left onto the Route des Princes and cross the D21.

(11) At the Carrefour des Botteaux, turn right into the Station alley. TheGR® turns left 400 m further on.

No signposts
Continue straight ahead. At the next signpost, turn slightly right onto Allée de la Ferrandière.
approximately 600 metres.

(12) At the crossroads, take the path on the right. After 200 metres, you will arrive near the hedge surrounding several houses. Turn right, then cross the hedge on the left to enter Rue du Papillon. At the end of this street, opposite No. 28, turn right and then take Rue du Petit Duc on the left.

(13) At Rue Lady Beauty Fidney, turn left, then left again at the next street and continue. At the second intersection, turn right onto Rue de la Solitude. You will see the Pontcarré Town Hall straight ahead. Continue to the car park (S/E).

This route is particularly enjoyable in dry weather, when there is no mud, as some sections are tricky to navigate without getting your shoes dirty.
You walk for miles under the cover of trees, with refreshing shade on hot days.
The paths are well marked, with the exception of the one before crossing the D21.
There were many hikers and cyclists out on the day of my hike, but they didn't cause any problems.
For a good walker, it's a 3-hour walk without any difficulties.

A beautiful hike, alternating between narrow paths and wide lanes. Be careful when crossing the D471 at Carrefour Tripier (km 8.2). Further on, the path leading to Ozoir-la-Ferrière station is blocked at the junction of Route des Etangs and Route des Charbonniers (km 8.9). Turn right onto Route des Charbonniers and continue towards Carrefour des Sangliers. Also at the Carrefour des Plants, do not turn left onto the Route des Princes (the D21 is difficult to cross at this point and the path opposite is not very visible; you will have to walk 50 metres along the busy D21), but continue opposite along the Chemin des Braques until you reach the Carrefour de la Ferrandière (the D21 is easy to cross).

A lovely walk, but I was very surprised not to have come across anyone else, given that it's such a pleasant place and the weather was perfect that day, with 25°C and bright sunshine.

A few details: between 2 and 3, cross the D 21, pass in front of an inhabited MF, opposite the information signs, further on to the right is a small pond.
Between 7 and 8, the Tripier crossroads is rather uninviting (rubbish dump) and the D 471 is difficult to cross, so it is best to take a detour to avoid this area.
Otherwise, it's a lovely walk

Very pretty route through the autumn forest. Quite muddy indeed with all the rain we've had over the last few days, but that didn't spoil our fun! Everything is very well signposted, thank you. One clarification: we took a detour at point 2 on the Chemin de la Bûcherie, as we saw a picnic area on the map, but it doesn't actually exist.

We chose this route because it was mainly in the forest, where the outside temperature was around 36°C.
There were a few beautiful forest trails, but otherwise mostly wide paths. There were no hikers, but a few cyclists.

A beautiful walk, but above all a beautiful forest. It is criss-crossed by numerous paths of all kinds. Some are paved, others are grassy, and there are even simple trails (much less well maintained). This means that there are all kinds of options to suit all tastes.
Returning to the route itself, the long climb northwards at the end of the walk is on a hard track, which I personally find too long.
On the other hand, the beautiful avenue of plane trees leading back to the car is majestic!

A very beautiful hike, peaceful and with exceptional views if you take the time to look around, and autumn is perfect for photos.
Given the weather in the days leading up to the hike, some of the paths were a bit muddy but passable. There were two tree trunks across the paths (passable) but they added a bit of surprise to the route.
You can start from the car park at Ozoir-La-Ferrière station, go under the railway line to reach point 8, and from point 12 go directly to point 1 to pass through the top of Pontcarré.
Or park in the car park between points 7 and 8 on Route des Etangs.
thank you.

very beautiful hike in the forest, accessible paths, nice weather. May be slippery in rainy weather. We spotted a deer that quickly ran away when it saw us. Otherwise, the route and description were accurate, good signage, and the distance was as indicated. Very good day.

Hike done in rainy weather. So no crowds. Beautiful hike, easy terrain and passable without any difficulties despite the heavy rain. The autumn colours were beginning to show.
Definitely worth doing.

A beautiful hike through pretty forest landscapes, and not too crowded despite choosing to do it on a Sunday. That said, the weather was quite uncertain. There are no difficulties, the forest paths are wide, and the hike is on almost flat terrain

A lovely Sunday hike with friends in beautiful weather. An easy route with no elevation gain. Much quieter in the afternoon once the cycling teams have left.

Walk mainly on wide, well-maintained paths. We were disappointed that there weren't more sections on forest trails.

Nice hike, but the scenery isn't very varied (which is to be expected in a forest). It would be more interesting to do this by bike.
