Description of the walk

The walk starts at the car park in front of the main gate of the Domaine de Rentilly, Route de Guermantes (D217b) in Bussy-Saint-Martin.

(S/E) Cross the D217b and enter the park. After studying the map to memorise the layout of the different areas, take the path on the left towards the Grille de la Brosse. It runs roughly parallel to the Route de Guermantes.

(1) At the Grille de la Brosse, turn right towards the château (signpost).

(2) Go around the château, passing in front of the main façade. Then follow the ponds until you reach the third lane.

(3) Turn right and go down a few steps. Continue and turn right at the next crossroads, then left into the lane at the corner of a grassy retention basin. Two hundred metres further on, turn right and continue towards the Grille des Gardes.

(4) Turn left into the lane closest to the one you have just left. It goes back up into the woods. Follow it to the park fence, where it turns left into a rectangular clearing.
Take the first lane on your right. It ends at the lane surrounding the French garden. Turn right and, after going around about a quarter of the statue, turn right onto the path that leads to the Grille Noire du Parc.

(5) Leave the park. Cross the moat bridge, turn left at the Rond-Point de la Grille Noire, cross Rue de l'Étang and, a few metres further on, turn left onto the path leading to the Vallée de la Brosse (see signpost). This path arrives after a left turn near a white metal cross on the edge of a housing estate.

Continue along Chemin de la Croix Blanche, then, after passing through the gate, turn right onto Chemin de l'Étang de la Broce (see sign on the post).

(6) At the roundabout, take the wide tree-lined lane closed off by low walls forming chicanes. Follow the path on the right, which curves to the right and runs alongside the Étang de la Broce.

(7) When the path reaches a multiple intersection, continue in the centre on the widest path that goes up the slope towards industrial buildings whose roofs are visible. You will reach a car park near the RER railway line.

(8) Cross the car park and the road to take the path opposite that runs alongside the RER line on your right. After about 300 m, at a crossroads, turn left into the tree-lined lane (on the right-hand side there is a footbridge over the railway line). After about 100 metres, turn right onto the path. You will arrive at a lake, which you will go around on the left.

Cross Boulevard de Lagny (on your left on the opposite pavement is the "Villa Bellagio") and continue straight ahead. Follow the curved lake to reach Rue Bernard Palissy, which you follow to the right. At the crossroads with Avenue du Général de Gaulle (traffic lights), continue straight ahead along Boulevard Pierre Mendès France and turn left into Place Fulgence Bienvenüe.

(9) Pass the Bussy-Saint-Georges RER station and continue to Rue Henry de Monfreid, which you take on the right. After passing over the RER, go down the sloping path on the left at the edge of the lake and continue along its left bank. At the next intersection, turn left onto the path that takes you over the RER line again to arrive on Avenue du Général de Gaulle.
Cross the avenue and continue straight ahead along Boulevard Thibaud de Champagne until you reach the Notre-Dame-du-Val church.

(10) Go around the church on the right and continue around the lake to rejoin Avenue du Général de Gaulle, which you take on the left. Follow the avenue for 500 metres and turn right onto Boulevard des Genêts towards Parc Gustave Eiffel.

(11) Follow it, cross the RER tracks and continue to the Esplanade des Religions. Turn left onto Allée Madame de Montespan towards the Fo Guang Shan Temple.

(12) Continue to the Tawba Mosque.

(13) Immediately after the mosque, turn left onto the path leading to the RER footbridge. Continue and cross Avenue du Général de Gaulle again, then follow Promenade Jacques de Thou for about one kilometre.

(14) At the end of this road, turn right onto the paved Mail du Promeneur. After about 500 metres, it becomes an unpaved track that turns left and descends towards the bottom of the valley. It crosses two roads, which you cross, first the D217b and then the D10.

(15) You are now at La Petite Jonchère, near a pond hidden by vegetation (however, a path crosses it on the right and allows you to approach its shore). Continue towards Conches. The track turns left, runs alongside the Ru de la Gondoire, then the D10 until it crosses the road leading to Chanteloup-les-Vignes.

(16) Turn left into Ruelle Sainte-Jeanne and, a few metres further on, turn left onto the track towards Conches. The track runs alongside the Ru de la Gondoire and a riding centre for about 500 metres, then turns right. At the T-junction with Ruelle Sainte-Jeanne, turn left and continue to Rue du Fort du Bois. Go straight ahead into Rue du Châtelet and follow it. It winds for one kilometre and reaches Rue Ferraille at a T-junction. On the right, a barrier closes off the unpaved road.

(17) Turn left onto Rue Ferraille (this section is paved). It crosses the stream and is unpaved after the intersection. Continue straight ahead to reach the D217b. Turn left, then 200 metres further on, turn right onto Rue Chevret and follow it for about 100 metres.

(18) Turn right onto Chemin de Malvoisine. At the boules court (next to a tennis court), turn right to join the D217b next to the church. Follow the D217b to the left and, at the crossroads, turn right onto the D35 towards Gouvernes. Cross the D35a.

(19) Turn left onto the path running alongside the stream. After 300 metres, this path leads to a gate opening onto the D35a. Cross the road and continue straight ahead towards the cemetery. Turn right onto the road that becomes a private road for about 50 metres at the intersection with the large avenue lined with very tall poplar trees (there is no no-entry sign). At the next T-junction, take the track on the left which climbs up towards the D217b, which it joins near the entrance to the Château de Guermantes. Turn right and follow the track running alongside the D217b a few metres below. After a winding descent, you will cross the Ru de la Brosse on a footbridge

(20) Continue right towards the Étang de la Loy. The path follows the left bank of the Ru de la Brosse. Cross the next footbridge and the path will now approach the bank of the Étang de la Loy.

(21) At the crossroads, take the path on the left over the dam. This will take you to the edge of a housing estate where a signpost at the first fork indicates the direction of the Parc Culturel de Rentilly. Do not turn, but continue until you reach a very large tree-lined avenue, which you take on the left (a signpost also indicates the direction of the Parc Culturel de Rentilly). Continue. At the end of this lane is the car park, which is the starting point for the tour (S/E).

a beautiful hike, especially for the beauty of the park and its remarkable trees. As for the trail outside the park, it is best to do it in mid-season as it is very exposed.

A varied walk combining forest, fields and a new town. No particular difficulty. The detour via Guermantes may be unnecessary. A very pleasant walk

The route was well explained, except for one spot where it said to take the horse trail, but there was no sign to indicate this. However, it wasn't a major problem to get to the right place. Rentilly Park is well worth a visit

A route well suited to families: our 9-year-old children had no problems.
We set off from the car park in Bussy St-Martin, which allows you to hike and then have a picnic in Rentilly Park before finishing the route.
Best regards

A superb hike alternating between town and countryside. If you set off early in the morning, you may spot deer in the grounds of Rentilly Castle, and if you are available on Sunday 16 June 2019, come and watch the Marne et Gondoire marathon, which starts and finishes in this wonderful park.

A very beautiful hike with no difficulty. After point 19 and the cemetery, to descend and cross the stream, it would be good if this steep slope were made safer. It should be avoided if the ground is wet.
Thank you to the author of this beautiful route, which we did from station to station (Bussy-St-Georges-Bussy-St-Georges)

We followed the instructions word for word, without any problems. The description was very precise with additional landmarks.
A very pleasant walk, between a developed town and nature. Animals, lakes, pretty woodland.
Would definitely do it again.
We will definitely do it again.
Thanks to the person who prepared this description.

I was worried that the route would be more urban. In the end, the route through Bussy-St-Georges avoids the main roads. It's a very pleasant route, starting from the RER station in Bussy. My friends and I were able to enjoy this beautiful sunny day with a picnic by the Loy pond.
The route description is very good.

Thanks to this Valjovian hiker for this beautiful route
i brought a group of 10 people, all of whom thoroughly enjoyed the day
The section through Bussy, point 12, is now well laid out, even though work is still ongoing. There are benches in this green corridor, which are very handy for a lunch break.
However, I started this hike in the north and finished in Rentilly Park.
The scenery was varied and the hike was fairly easy overall
