Description of the walk

(S/E) With your back to the station and facing the shopping centre, turn right onto Rue des Deux Communes, following the yellow-red and yellow markings, pass behind a car park, then in front of the petrol station. Continue down the street to the roundabout, cross at the pedestrian crossing and head left. Pass in front of the Claude Galien Hospital and arrive at a fork.

(1) Leave the D330 and turn right onto Rue du Moulin de Jarcy. Cross the Yerres in front of the mill. Walk up the street that runs alongside the wall of the former Jarcy Abbey.

(2) Turn left at the pedestrian crossing and follow the signs. The path passes through the meadows of an equestrian centre, then runs alongside the Yerres, veering away from the marshy bank. After a curious wooden structure (?) by the river, the path climbs uphill. Go through the barrier preventing vehicle access. Take the street on the right for a few metres to see the "Closerie Falbala" through a gate.

(3) Retrace your steps and take the path on the right that runs alongside the Jean Dubuffet Foundation. After the right-hand bend, you will come to a tarmac road, which you quickly leave by taking the Chemin des Maisons Rouges on the left. At the end of this road, turn right onto Rue du Moulin Neuf. After a few dozen metres, turn left onto Rue des Plantes and continue for about 150 metres.

(4) Turn left onto a path that descends through a small wood. This leads to Rue des Roissières. Follow this street and take the second right onto Rue des Lilas.

(5) Cross Rue Georges Coubard at the pedestrian crossing, and after 100 metres turn left onto Rue de la Sablière. This road turns right, opposite a school complex. On the right, take a path that leads into a wood. On the left, you will see a cemetery. Continue to the fork at the end where the path splits in two.

(6) Take the left fork which descends and then, after a few dozen metres, take the small path on the right. This leads to a tarmac road which you should follow to the right towards the Moulin de Rochopt. Before you reach it, take the footbridge over the Yerres above the dam. On the other bank, turn left and follow the path that goes up the river. After about 600 metres, go under a bridge decorated with street art frescoes.

(7) Continue along this path, which sometimes splits into several branches that rejoin further on (take the least muddy one). Ignore a bridge on the left and go around the football pitches on the left.

(8) Leave the banks of the Yerres, cross the tarmac road and take the street opposite, which climbs towards the Forest of Sénart. Pass under the railway bridge and continue for about 400 metres.

(9) Take the path on the left (yellow markings) to the edge of the forest.

(10) Pass in front of the Collège André Dunoyer de Ségozac, then turn left and take the footbridge over the dual carriageway. At the end, turn immediately left into the lane that runs between the buildings. At the end of the lane, turn right to reach the station (S/E).

Thank you very much for this lovely, easy and bucolic hike; having lived in this area for 24 years, I still discovered new places.
This walk is very well documented, so well done to whoever took the time to guide us so well.

Very wet area after the Moulin de JARCY for about 1 km.
Best visited in summer.

A very pleasant walk for a sunny Sunday afternoon with a beautiful variety of landscapes (forest, village, riverbanks, fields, etc.). Not very difficult and very little elevation gain.
This is an interesting area of Essonne, which may not seem particularly conducive to hiking but offers this unexpectedly beautiful nature outing.

The start is in the middle of the city, but once you leave it behind, it's pure bliss.
A very varied hike through the city, along rivers, through nature, past street art – a wonderful discovery.
The section from point 6 wasn't very clear to me. The small path on the right isn't very visible. The section from this small path to the little descent to join the road is an open-air toilet... And I found myself on a small, rather dangerous downhill path to reach the road. I wondered if I had taken the wrong path...
Despite everything, it's a walk that I recommend.

A pleasant little walk, but too muddy along the banks of the Yerres. Best done in summer when the weather is dry. It's surprising to come across the Closerie Falbala on the way back up.

I had already done this hike with the old version, where we took a path much higher up the hill after the Jarcy mill. The new route is much prettier. Well done to those who made it. Happy New Year to all. Jacques
