Park at the Marolles-en-Brie golf course car park.
(S/E) Head east (towards the river) and follow the yellow PR® trail along the lawn on your right.
(1) At the edge of the golf course, turn right. Reach Le Réveillon, walk along it and take a small tunnel under the N19. On the other side, walk along Le Réveillon on your left and pass under the railway bridge. On the other side, go up to the right and join the path marked "Végétale" on the map.
(2) Turn left at the hairpin bend and follow the platform of an old railway line. Stay on this good, stable path for a long time. Walk alongside a nursery on your right and join the old Mandres-les-Roses station (not shown on the map, but indicated by a sign on the building). Cross the D252 (Rue de Verdun) with caution and continue to the end of the road.
(3) Turn right. At the pumping station, first turn left then right towards Domaine de Rosebrie. The road turns right at the greenhouses. Take the first road on the left and join a GRP®.
(4) Follow it to the left (red and yellow markings). Walk along the greenhouses on your left, then the Bois de Saint-Leu. At the intersection at the corner of the woods, continue straight ahead.
(5) Take the bridge over the TGV line and, ignoring the side roads, continue along the road until you reach the N19.
(6) Cross the road carefully and continue straight ahead on Avenue Pierre Guerin. Further on, continue along Rue de la République. Cross Rue de la Poste on the right-hand side, pass in front of the Château de Servon (linked to Anne Boleyn, Queen of England) and arrive at the church.
(7) Just after the church, continue along the GRP® trail by taking a passage on the left. Continue along the tarmac road and take the first right, Rue de la Dehors, then the first left, Ruelle Baron. Continue along the Servon ponds, following the GRP® trail.
(8) After the first pond, leave the GRP®, turn left onto the footbridge and pass between the two ponds. Then turn right and walk along the second pond on your right, then the third.
(9) Return to the GRP® and follow it to the left. Take the first path on the right to Avenue du Général Leclerc.
(10) Turn right and cross the Réveillon. At the crossroads shortly afterwards, turn left into Grande Rue. Take the first right, Rue de l'Église, and follow it to the church.
(11) Continue left, still on Rue de l'Église (yellow markings). At the next intersection, turn right onto Rue de Marolles and pass in front of Château de Santeny, located on the right.
(12) At the next intersection, take the second left, Chemin des Vignes (yellow markings). Follow this single track until you reach Rue Chasse Lièvre. Cross a small road, continue straight ahead and you will immediately come to a T-junction.
(13) Turn left with the PR® and walk along a wall on your right. You will come out onto Rue de la Fontaine Froide and follow it to the right. Ignore two turnings on the left and you will reach a new intersection (Marolles church on the right).
(14) Then turn left at an acute angle. Take the first path on the right. Reach Le Réveillon and follow it on your left. This will take you to a junction you passed at the start of the walk.
(1) Continue straight ahead and you will soon reach the car park (S/E).
