Start from the car park at the end of Rue Pierre et Marie Curie, near the river stop.
(S/E) The walk begins by following the Pâtis de Saint-Jean eastwards, along the left bank of the Marne to the bridge.
(1) Go under the bridge, turn right onto the path that climbs up to the road, which you follow to the right. Cross the Marne and immediately afterwards, turn right onto the Chemin des Îles, which runs along the right bank of the Marne. Head up to the left onto the D3E road.
(2) At the roundabout opposite Changis station, follow the D53 for about 300 m; this road crosses over the railway line leading to Jaignes.
(3) Turn right onto a farm track that heads straight towards the Bois de la Muette and its forest lodge, which you pass; continue through the woods for 500 m and, just before a private track, take the path on the right that descends to a road waste disposal site, which you go round on the right until you reach the railway line.
(4) Turn left, follow the railway line for 250 m, go under the motorway through the tunnel and cross the railway line via the bridge to come down onto the D3E road.
(5) Cross the railway line to take the farm track to the football pitch at a place called Les Vieux Moulins.
(6) Turn right onto the path, after the yard of a building firm, which leads to a small bridge that you cross. Follow the path running along the right bank of the Marne to the Pâtis de Ussy-sur-Marne, then cross the campsite and go under the bridge (caution: slippery banks in wet weather).
(7) Cross the bridge over the Marne and follow Rue d’Ussy to Sammeron.
(8) Cross the D603 road at the shops and head up Rue Cassine on the opposite side until you reach the junction with a path.
(9) Take the Pré Maquais path on the left, which winds its way between woods and houses to join Rue Gaulde, which you follow to the left for 100 m.
(10) Turn left into Rue du Four, then immediately right into Rue du Tarcq, which you leave on the right to take Rue de Coulommiers, behind the bridge over the Ru de la Bécotte (red and white markings). Continue along a path.
(11) Turn onto the second path on the right, a track that runs alongside the woods to a ford, which you cross.
(12) Take the Route de Signets on the right for 200 m and turn into the first path on the left, which climbs towards the hamlet of "La Grange au Bois", and follow the edge of the woods on the left until you reach the Dhuis.
(13) Follow the Dhuis aqueduct on the right; continue after crossing the road leading to the hamlet of "Montretout" on the right. Carry on until you reach the motorway.
(14) Head left for about 100 metres and cross the motorway via the tunnel located below the Dhuis aqueduct inspection chamber. At the exit, turn right and rejoin the aqueduct, following the field on your left, running alongside the motorway. Walk back up to the aqueduct inspection chamber and turn right towards the hamlet of Arpentigny, still following the Dhuis.
(15) Continue along the Dhuis aqueduct after crossing the road, then cross two more roads leading to the hamlet of Les Deux Jumeaux and carry on through the Bois de la Garenne.
(16) Turn right, just after the hamlet of "Les Ambroises", onto a cobbled path leading 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, continuing until you reach Rue Pasteur (D603), which you cross to reach Rue Pierre Marie Curie.
(18) Turn left onto this street to reach the river landing stage (S/E).
