Walk in the footsteps of Cosette

This hike from Vaujours to the Moulin de Montfermeil, via the Promenade de la Dhuis and the Forêt de Bondy, often follows marked paths known as the Chemins de Cosette, in reference to Victor Hugo's novel Les Misérables, in which these places served as the setting for the meeting of the two main characters: Cosette and Jean Valjean.
Beyond this literary reference, the route, often along the upper reaches of the rolling hills, offers some very pretty views.

Description of the walk

The hike starts at the car park of the church in Vaujours (Seine-Saint-Denis).
You can get there by car or public transport. Bus 642 serves the Vert Galant (RER B) and Le Chenay-Gagny (RER E) stations. The Giffard or Montauban stops, depending on the direction of the bus, are the closest.

Yellow and red markings (GRP® Ceinture Verte de l'Ile de France)

(S/E) Walk along the cemetery wall, heading up towards the woods, then take the path bordered by two wire fences that runs alongside properties and ends with a staircase leading down to Rue de Coubron.
Turn right and continue along this street until you reach the roundabout, which you cross to reach the Route du Bois de Bernouille opposite.
After about 200 metres, you will come to the junction of this road with Promenade de la Dhuis, which is easily recognisable with its two lanes separated by a grassy central reservation.

(1) Turn right and follow this promenade to the D136, opposite a gate leading into the Bondy Regional Forest.

No signposts

(2) Enter the park and turn immediately left, then a few metres further on, turn right into Allée des Étangs, where you will walk to Étang Laurence.
Turn right onto the dyke separating the Laurence and Isabelle ponds, then walk past the Frère Jean fountain located below on your left

(3) Take the path that climbs almost opposite you. At the second crossroads, turn left and continue. You will leave the Bondy Regional Forest near an archery range on Boulevard Hardy de Montfermeil.

(4) Turn right, then immediately left onto Rue de la Haute Futaie and continue to Place Jean Mermoz (in front of the Town Hall).

(5) Cross the square and take Rue du Lavoir, which you follow until you reach Chemin de la Fontaine Lassault. Turn left.

(6) At the next crossroads, turn right onto Rue du Docteur Laennec in front of a wash house and Fontaine Lassault.

yellow and red markings

Continue. The street changes name at the next crossroads and becomes Rue Curie, which ends in a cul-de-sac, but a track turning right uphill allows pedestrians to reach the Sempin mill in Montfermeil.

(7) Continue right along Rue des Moulins and, near the hospital, turn left onto Rue du Général Leclerc, which slopes downwards. Four hundred metres further on, turn right onto Chemin de la Jarrie, then further on, turn right again onto Rue de la Fontaine Jean Valjean.
You will see the Jean Valjean Fountain leaning against the wall at the end of a small square on your right

(8). Cross the street and enter Parc Jean Valjean. A concrete path takes you up through the arboretum and out again at the château, onto Rue de l'Église. Continue to the right until you reach Rue Grange, where you turn left and then, a few dozen metres further on, right into Rue de la Halle to arrive at Place Jean Mermoz in front of the Town Hall.

(5) Continue right along Rue de Coubron, then turn left onto the old Coubron road. Turn left onto Chemin de la Petite Montagne, at the end of which you will enter the woods via a footpath.

_Various signposts__

The path descends to Boulevard Hardy, which you cross, along with the car park opposite, to enter the Bondy Regional Forest through the gate at the end of the fence. Continue straight on to the Carrefour de l'Étoile des six routes, where you will find a large sign with a map of the park.

(9) Turn right onto Chemin de la Porte de Coubron-Corot and leave the forest through this gate. A few dozen metres further down, the path ends at Allée du Parc. Follow it to the left, then continue almost opposite along Rue Raoul Larche and, at Rue Jean Jaurès, turn left to go to the town hall, where you enter the park to cross it and exit opposite the Maison de la Nature.

No signposts

(10) To the right of the Maison de la Nature, take the Sente des Vignes and continue. At the junction with the Sente des Platrières, turn right onto the latter.

(11) You will pass in front of the Clos de Bréon. At the next crossroads, turn left onto Chemin Montauban and continue until you reach the junction with Promenade de la Dhuis.

GR® trail markings (red and white)

(12) Turn left and continue to the Route du Bois de Bernouille.

(1) Turn right to go up to the roundabout. Cross it and go down Rue de Coubron to the steps on the left of the Les Jardins du Renard residence.
Climb the stairs and continue along this path, which will take you back to the church car park. (S/E).

I was leading a group of 27 hikers.
We didn't go to points 6 and 7 to avoid the pavements and tarmac.
We went straight to the Jean Valjean fountain and spent quite a bit of time in the Arboretum.
We enjoyed our lunch on the steps of the Château des Cèdres in the sunshine.
A little mud between 11 and 12.
A nice, easy hike.

A walk on a Saturday afternoon under bright sunshine. However, the forest paths were very muddy. The walk along the aqueduct and through the forest is pleasant. I am more sceptical about the appeal of the loop in Montfermeil. I was not particularly impressed by the charms of the residential areas. An easy walk that can be completed in three hours.

Starting from the beginning, it all makes sense... when we reached point 8, we didn't do the "lower" loop (we didn't have time) and "climbed" back up to point 9 to finish the hike.
The forest sections are very pleasant. We enjoyed a beautiful morning, which is why there were so many walkers, joggers and cyclists (but no horse riders... ).
Our route was about 11 km long.
Between point 4 and halfway between 8 and 9, the hike only takes you along unpleasant city streets.
PS: as usual, we "cleaned up" the route. Although we regularly found bins in town where we could empty our bags, in the woods, despite the bins at the edge, we found too much litter for such a beautiful setting. Is it for safety reasons that they don't put bins under the trees?

A very pleasant walk that allows you to discover a changing suburban town with a mix of old and new.
The route through Bois de Bondy is very safe and not muddy.
Crossing Jean Valjean Park is so hazardous that you won't even see the fountain!
The mill district has its own charm. I recommend this walk.

It's really nice to hike in this little corner of the 93, which is still relatively unspoilt. We replaced the route in Montfermeil, which was a little too urban for our taste, with a detour to Coubron to revisit some memories! There are a few changes to the route, which are easy to understand with the map.

A very exotic hike that allows you to see a bucolic 93.

Please note that the staircase on the first stage leading to Rue de Coubron has since been closed off. You can walk down the small embankment if the ground is dry, otherwise get off at the Chemin du Renard bus stop (line 643), which will take you almost to this level.

It was pure pleasure discovering the mill, the park and the fountain, as I was used to mountain biking on the trails around this hike.
Thank you.

A beautiful hike to discover well-known but little-known places. The passages through Bondy Forest and Jean Valjean Park allow you to discover these different places. Even though I didn't know the second one. Some friendly encounters along the way, including some explanations about the Montfermeil mill.
The landmarks in Jean Valjean Park are rather vague.
I highly recommend this walk.

A pleasant hike. Despite my announcement on the website, I did this hike alone. Despite the forecast rain, I had superb weather except during my picnic in a quiet little park just past the Montfermeil mill. I discovered some interesting sites, but there was one small downside: major construction work in the town centres of Montfermeil and Coubron. The description of the route through the centre of Coubron will probably need to be revised due to the ongoing works and developments. In addition, works in Jean Valjean Park have led to the closure of the park opposite the fountain. I was forced to walk back up the steep slope I had just descended through the streets and I didn't see the arboretum, which seemed to me to be one of the main attractions of this hike. The section of Coubron after the Maison de la Nature to the Dhuis aqueduct is particularly pleasant. Along the Dhuis embankment, there are beautiful purple orchids in full bloom (Orchis purpurea). Another highlight is the church in Vaujours at the start and finish of the walk and its small cemetery, which offers a beautiful view.

a very varied walk (hillsides with unobstructed views, forests, educational panels, a mill, fountains, an arboretum... and an aqueduct underfoot) which was very pleasant. I took my time and covered the 15 km in 3½ hours wearing low-cut hiking boots. The hour and a half of walking through the town isn't too difficult (quiet residential areas), you just need to avoid wearing stiff mountain boots. There are almost no muddy sections. The description is very precise, so there's no risk of getting lost. Highly recommended.
