Departure from the car park at the end of Rue Pierre et Marie Curie, near the river stop.
(S/E) The hike begins by following the Pâtis de Saint-Jean eastwards, on the left bank of the Marne to the bridge.
(1) Go under the bridge, turn right onto the path that goes up to the road on the right. Cross the Marne and immediately after, take the Chemin des Îles on the right, which runs along the right bank of the Marne. Go up to the left onto the D3E road.
(2) At the roundabout opposite Changis station, follow the D53 for about 300 metres, a road that passes over the railway line leading to Jaignes.
(3) Turn right onto a farm track that leads straight to the Muette woods and its forest house, which you pass to continue into the woods for 500 metres. Before a private road, take the track on the right that descends to a road waste disposal site, which you go around on the right until you reach the railway line.
(4) Turn left, follow the railway line for 250 metres, pass under the motorway through the tunnel and cross the railway line via the bridge to descend to the D3E road.
(5) Cross the road and take the farm track to the football pitch at a place called Les Vieux Moulins.
(6) Turn right onto the path after the masonry company's depot, which leads to a small bridge that you cross. Follow the path along the right bank of the Marne to Pâtis de Ussy-sur-Marne, then cross the campsite and go under the bridge (be careful, the banks are slippery when it rains).
(7) Cross the bridge over the Marne and follow Rue d'Ussy to Sammeron.
(8) Cross the D603 road at the shops and go up Rue Cassine opposite until you reach the junction with a path.
(9) Take the Pré Maquais path on the left, which winds between woods and houses, to reach Rue Gaulde, which you follow to the left for 100 metres.
(10) Turn left onto Rue du Four, then immediately right onto Rue du Tarcq, which you leave on the right for Rue de Coulommiers, behind the bridge over the Bécotte stream (red and white markings). Continue along a path.
(11) Turn onto the second path on the right, a trail that runs alongside the woods to a ford, which you cross.
(12) Take the Route de Signets on the right for 200 metres and turn onto the first path on the left, which climbs towards a place called "La Grange au Bois" and runs along the edge of the woods on the left until you reach the Dhuis.
(13) Follow the Dhuis aqueduct on the right, continuing after crossing the road that leads to the hamlet of "Montretout" on the right. Continue until you reach the motorway.
(14) Cross the motorway via the tunnel below the Dhuys culvert and rejoin the aqueduct by walking along the right-hand side of the field bordering the motorway for 100 metres. Walk back up to the aqueduct culvert and turn right towards the hamlet of Arpentigny, still on the Dhuis.
(15) Continue along the Dhuis aqueduct after crossing the road, cross two more roads leading to the hamlet of Les Deux Jumeaux and continue through the Bois de la Garenne.
(16) Turn right just after the place called "Les Ambroises" onto a paved path that leads to the centre of Saint-Jean-les-Deux-Jumeaux via Rue Alfred de Musset (red and white markings).
(17) Turn left onto Rue du Général de Gaulle, continue to Rue Pasteur, cross the D603 and join Rue Pierre Marie Curie.
(18) Turn left onto this street to reach the river stop (S/E).
