Panoramic view of the Marne between Saint-Jean-les-Deux-Jumeaux and Ussy-sur-Marne

Our route offers the chance to observe the wildlife along the banks of the Marne, and the return journey provides views of the open landscapes of this valley. The route is accessible in winter, though there are a few muddy patches above Sammeron; there is the option to have a picnic at the tables at the river stop.

Description of the walk

Departure from Changis-sur-Marne station,
- Transilien - Line P, on the section between Paris-Est and Château-Thierry via Meaux.

(S/E) Go under the tracks via the underpass, follow Rue de la Gare, pass the old café, then turn right onto Rue du Moncey, turn left into Rue du Vieux Saule, turn right onto the right bank of the Marne, climb the stairs and cross the Marne via the bridge.

(1) Turn left, walk down alongside the Marne and follow the path on the right for about 4 km, ignoring the turn-offs on the right; go under the A4 motorway bridge, continue to Ussy-sur-Marne, which can be admired from the opposite bank.

(2) About a hundred metres before a road bridge, just after the summer leisure grounds, turn right at a 90° angle onto a farm track. Then turn left onto this track, running alongside the D603. Cross the D21p (Rue d’Ussy) then first turn left then right to the pedestrian crossing.

(3) Cross the D603 (Rue de Metz) and head up Rue Cassine opposite. Join Rue Gaulde and follow it to the right (south-west). Continue along Chemin de la Grange au Boi, which is tarmac at the start and then grassy. Climb to the edge of a wood, ignoring the side paths.

(4) Continue south-west along the edge of the woods, still climbing. Reach the Dhuys (underground aqueduct).

Red and white markings

(5) Turn right onto a hard-packed track and follow it to the junction with a tarmac road (Route de la Choquette).

(6) Turn right and head downhill to the hamlet of Montretout. At the T-junction, turn left onto Rue de Sibut. Leave the hamlet and continue along the road that crosses the A4 motorway.

(7) Take the path on the right along the Dhuys aqueduct embankment. Cross two small roads. After a series of left and right bends, ignore a path leading uphill to the left and you will soon reach another junction.

End of red and white markings

(8) Then take the path that descends steeply to the right. Cross a road and go down a flight of steps. At the bottom, turn left onto a path and you will immediately come out onto a road.

(9) Turn right (Rue Paul Tripier) then take the first street on the left.

(10) At the end, follow Rue Alfred de Musset to the left. Turn right into Rue du Général de Gaulle and continue all the way to the traffic lights on Rue Pasteur.

(11) Cross Rue Pasteur (D603) at the pedestrian crossing and continue straight ahead. At the first junction, continue straight on then turn right to reach the left bank of the Marne.

(12) Go under the bridge, turn immediately right, go back up onto the road (red/white markings), then turn right to cross the bridge and go down the steps, go up Rue du Vieux Saule and turn right into Rue du Moncey. Turn left into Rue de la Gare and rejoin the (S/E).

We were travelling by car and set off straight away, parking near the bridge on the outskirts of Saint-Jean-les-Deux-Jumeaux. The first section, which runs alongside the Marne, is a bit of a let-down as you can’t see much of the river, which is hidden by tall trees. The path seems to be little-used, with quite tall grass. After that, it’s pleasant but nothing special; the landscape is open, certainly, but you never see the Marne except right at the very end. Between points 4 and 5, we’re on private property, which is indicated by a sign. In Sammeron, there’s a very good shop selling local produce. We had bad weather, but in fine weather, it’s surely more enjoyable.

Good evening. I did it on 17 March and it was a perfect walk, but I preferred to do it the other way round so that I could tackle the climb in the morning and go via the Dhuis aqueduct rather than along the road; the underpass beneath the A4 is perfectly passable.

Hello, thank you for your comments. I hope you enjoyed the walk in this spring weather; at point 4, it is indeed a path, but the farmer wants to claim it as his own!

At point 4, you are not allowed to go through the edge of the woods, but you can take the path on the left and continue straight on until you reach the GR11 on the right and point 5
At point 6, instead of following the GR11 along the road, cross the road and continue along the Dhuis aqueduct, which passes under the A4 and joins the GR11 at point 7
If the station car park is full, there is a car park at Place du Docteur Cruchaudeau in Changis-sur-Marne

I never found the little path at point 8, so I had to improvise for the end of the walk
Not recommended in hot weather; there’s practically no shade along the route.

Lots of fields and a bit monotonous at times. Some sections are rarely used and poorly maintained. Nevertheless, it’s a pleasant outdoor walk, especially through the villages.

A pleasant route, with the first section following the Marne river and the second section winding through the hillsides, offering lovely views.
Lack of picnic spots and no points of interest along the route

A very pleasant walk: a stroll along the Marne, then through the fields on the edge of the forest. For animal lovers, we spotted swans, geese, horses, donkeys, sheep and goats... There are no particular difficulties on this route. Picnic tables and benches are available at the start and finish of the route.

Hello, I had planned to do this route tomorrow, 8 February, but given the rain over the last few days, I’ve decided against it for fear of too much mud and will do it at a later date. Thanks to whoever mapped it out.
