Parking on the Place de l'Église in Orly-sur-Morin (on the D31, 12km south-west of La-Ferté-sous-Jouarre and 20km north-east of Coulommiers). For access by public transport, see the practical information.
Yellow markings
(S/E) Take Rue de l'Hêtre (sic) towards Sablonnières. Cross Ru de la Fonderie and walk along a triangular square on your right. Before leaving the village, turn left onto Rue du Chêne Madame. At the end of the street, continue north-east on a grassy path that climbs gently, winding between the meadows. Enter a wood, where the path becomes wider. Ignore a smaller path that branches off to the left and, after a bend to the right, you will come to a small road.
No markings
(1) Leave thePR® on your right and take the road on the left. As you leave the woods, you will see a large farmhouse to the north-east. Leave the farmhouse on your right and continue along the tarmac road. At the fork, turn right and you will immediately come out onto the D55.
Yellow markings
(2) Turn sharply right and follow the road to the village of Boitron.
No markings
(3) At the entrance to Boitron, ignore the yellow cross, walk past the cemetery and enter the village. Continue along the main road (due south).
(4) Turn left onto Rue des Moines. After a few metres, take the street on the left and then immediately turn right onto a narrow tarmac road heading due east. Follow this road across fields for about 1.2 km, ignoring a road that branches off to the right at elevation 182.
(5) When the tarmac ends, turn right onto a grassy path between two plots (there is a clump of trees in the middle of the left-hand plot). Walk along a meadow, descend slightly and you will come to a small road.
Yellow markings
(6) Take the road on the left. Cross a small wood and then the hamlet of Marlande.
(7) On leaving Marlande, just before the road sign, take a street on the right and walk alongside a house with a well. Continue along the path that runs alongside a meadow on the left. At the next fork, do not take the path opposite that goes down into the woods, but turn left and continue along the meadow. You will reach the hamlet of Jariel.
(8) Take the road on the right. After a few metres, when the road bends to the left, continue straight ahead, slightly to the right, into a street with a house with bright blue woodwork and ironwork. Pass the house: the village of Sablonnière appears lower down on the left. Continue south, descending between the meadows. Pass a yellow arrow on a fence post (the indicated turn is further down) and come out onto a perpendicular path.
(9) Turn left and walk towards the houses. Take the road on the right that descends towards Sablonnières. At the junction with the D31, turn left. Walk past the war memorial and cross the bridge over a river (wash house on the left).
No signposts
(10) Turn right onto the D222 towards Rebais and cross the Petit Morin.
(11) Opposite the cemetery, just before the sign for "La Chenée", turn right onto a path that heads west along a field. Pass the fenced-off buildings and then a small house at the crossroads. Continue along the same path, which curves north-west and runs alongside a circular section of the Petit Morin. This leads to a wider path.
Yellow markings
(12) From this point onwards, the path is none other than the platform of the old railway line in the Petit Morin valley: it is therefore wide and fairly flat. Take this path on the right. Ignore a smaller path that branches off to the right and then runs alongside the main path, which you should stay on.
(13) At the hamlet of La Forge, cross the road and continue straight ahead on the wide path. You will arrive at Coton, on the banks of the Petit Morin.
(14) Just after passing the old mill on the opposite bank, take the road on the right. Follow this road for about 250 metres (note the old small station on your left). When the road bends to the right to cross a bridge over the Petit Morin, take the wide path opposite, which starts just to the left of the "St-Georges" sign. Continue along the wide path, heading north-west, along the edge of the woods.
(15) At Moulin du Pont, at the fork near the houses with fences, take the right-hand path (signposted "Orly" on a fence post). After a few metres, leave the wide path and take a path on the right leading to a footbridge. Cross the Petit Morin river on the footbridge. At the end of the footbridge, turn left onto a grassy path.
(16) Cross a small road and continue straight ahead (north-west) on a grassy path. You will come out onto a small street that climbs for a few dozen metres. At the intersection, turn right. Immediately afterwards, at a small triangular square, take the left-hand lane. Then turn left onto Rue de l'Hêtre (D31) and continue to Place de l'Église (S/E).
