The route starts at Lizy-sur-Ourcq station and ends at Changis-Saint-Jean station. This means you stay on the Transilien P line (Paris-Est network).
(S) From the station, go straight towards Avenue de la Gare and follow it up to the roundabout opposite the town hall. Continue straight on to the Canal de l'Ourcq, whose banks can be seen above.
(1) Turn left and walk along the canal on your right until you reach the next bridge, the Pont de Belle Croix.
(2) Leave the canal, follow Rue Neuve for a few metres, then turn right onto Chemin de Villers-les-Rigault. Follow the path all the way to the pumping station. Continue along a shaded path between the Ourcq on the left and the canal above on the right. This will take you to a pumping station.
(3) Take a path on the left and go around the building on the left. Walk along the Ourcq on your left, then cross the river via a footbridge.
(4) Turn left and walk along a cultivated field. You will reach the confluence of the Ourcq and Marne rivers. Turn left and continue along the field. Walk along the Marne to the railway bridge.
(5) Pass under the bridge, continue along the Marne and then follow Rue du Port. Come out onto Grande Rue and first turn right then left onto Avenue Trois Vallets. Follow this road to its end.
(6) Continue along a path between the Marne (on your right) and cultivated fields (on your left). Pass by the foot of the church in Tancrou and you will come to a roundabout.
(7) Take the first right. Keep the Marne river at a distance on your right, barely visible through the branches. Pass a ranch-like building on your right. The road becomes a shaded path just after a barrier for cars. Continue straight ahead until the path joins the D53, known as Route de la Pente du Moulin.
(8) Follow the road as it continues (be careful, watch out for traffic). Continue to the bend that climbs 90° to the left, passing a farm on your right. Follow the bend as it climbs and turns into a hairpin bend until you reach the woods a little further up.
(9) About 200 m after the bend, look for a clear path on the left-hand side of the road, which is stony for the first few metres and climbs towards the Bois d'Ussy. Do not confuse it with one of the clearings on the left just before it, which is not accessible. Climb up, paying attention to the yellow markings.
(10) As indicated by a yellow arrow, turn right. Further on, go around a forest house and continue straight ahead (yellow markings).
(11) Leave the woods and continue between the fields towards Changis-sur-Marne.
(12) Cross a small road and continue straight ahead through the houses in the housing estate. At the roundabout, continue straight ahead along Rue des Vieilles Vignes. At the end, ignore Rue des Acacias and turn left to reach Changis-Saint-Jean station (E).
