Description of the walk

Start: the hike begins in Allée du Prieuré in the village of Pomponne (Seine-et-Marne).

No signposts.

(S/E) Cross Rue du Port and continue straight ahead on the pavement of the D334 until you reach the crossroads with traffic lights.
Or, for a more pleasant route: enter the Arcades stadium, walk along the skate park and tennis courts, cross the stream via the footbridge and cross the square to reach the crossroads.

(1) Turn left onto Route de Bordeaux. Continue to the roundabout and turn right at the first street. After a few metres, cross Rue des Chênes and turn left onto Rue du Grimpe, which continues onto Rue du Bouillon. At the end of the street, turn left.

(2) After about 100 metres, turn right (north-east) onto the rural path (Chemin de Pomponne on the map). At the end of this road, turn right onto the small road leading down into the valley. Then turn left onto the track running alongside the Ru de Bouillon. At the next T-junction, turn right, then a little further on, turn left onto a path marked GR®.

GR®14Amarkings (red and white)

(3) Turn left and follow the GR®. After about 100 metres, the path turns right and follows the bank of a very steep-sided stream (the Ru d'Armoin). It ends at a street where you turn left. Continue to the Promenade de la Dhuis, with its two paths separated by a grassy central reservation.

No signposts.

(4) Leave theGR® trail on your left and turn right. A few metres further on, you will pass the "Dhuis 999" hectometre marker. Follow this promenade, east-southeast. It crosses Rue de Claye after about 300 metres. Continue to the "Dhuis 982" hectometre marker, which is slightly hidden by the grass. A few dozen metres further on, cross Rue de la Dhuis.

(5) Turn right onto the path between a row of houses and the fence of a wood. This sloping path ends 300 metres further down in Rue de la Dhuis. Continue downhill, cross the roundabout and continue along the right-hand side of the tree-lined avenue to the roundabout near the railway line.

(6) Turn left onto Rue du Chemin de Fer, which runs along the embankment. A little further on, go under the bridge on the right, then, at the edge of the Marne, turn right to follow the towpath. As you continue, you can see the Lagny Water Sports Centre and the Rowing Club on the other bank. At Quai de la Marne, turn left onto the path passing under the bridge.

(7) Continue along the banks of the Marne. The path approaches the railway line and, when you reach an industrial area on the other bank, you will find an underpass on your right leading to Rue du Port, which takes you back to Allée du Prieuré (S/E).

Notes

It is possible to get to this hike by public transport as the circuit is a loop and passes through Lagny-Thorigny Transilien station (near point (7)). For timetables, click here.
In this case, exit the station on the Lagny-sur-Marne side. Cross the street and turn right onto Rue de Marne, which will take you to the riverbank at point (7).

Wear hiking boots, as the ground is muddy along the Marne in winter.

Hiking on a Saturday morning.
The main attraction is the path along the Marne, which is quite popular with cyclists and joggers.
Parking in Pomponne is free, but more difficult during the week as it is close to Lagny station.
a bit too much road at the start, so take care

Easy and quick to reach by public transport, Lagny/Thorigny station, Transilien P line from Gare de l'Est station, close to Paris.
It's always nice to find yourself surrounded by nature just 35 kilometres from Paris, with beautiful yellow rapeseed fields, the banks of the Marne, woodland, rivers, birdsong...
and discover the Quai 59 third place on the banks of the Marne with its large terrace.
More popular on the banks of the Marne. We hardly use the description, mainly relying on GPS. Thank you for this easy hike

It would be time to correct point 3, where, due to impenetrable vegetation, it is impossible to follow the Armoin stream.
The description indicates that you have to turn with the GR, but this GR has clearly been diverted for a long time, as indicated on the hiking map

I confirm that after point 3, it is no longer possible to follow the Armoin stream. I decided to go straight ahead and follow the GR14 to catch up with point 4.

A pleasant little walk. Between markers 3 and 4, it was not possible to follow the Armoin stream (overgrown with brambles). At point 3, it would be better to continue on the GR14. We took a detour via the Armoin quarries to the north to catch up with the aqueduct.

We really enjoyed this lovely little walk around Pomponne and Thorigny. The description is clear. Of course, you're walking in built-up areas, but that was made clear from the outset and, ultimately, it's a really nice walk that takes you into the countryside and along the Marne. It makes me want to create my own walks. Thank you to the author of this walk.

A pleasant route, but not to be attempted in rainy weather
BE CAREFUL at point 2, take Rue du Bouillon directly
the path between points 3 and 4 is impassable due to excessive brambles and vines at ground level. Take the path at the ostrich enclosure, continue straight to the end of the path, then turn left

Hello,

i don't know this route, but I don't think any of them deserve to be called disappointing... if we suggest it and spend time writing about it, it's because we think it will be of interest to some people.

Just take a look at the map to see that it's in an urban area, not at the top of Taennchel.

well-described hike but uninteresting. After struggling through uninteresting pavilions and encountering crowds of people going to see ostriches, we endured this hike where there is more tarmac than grass and no scenery worth seeing: avoid at all costs!

A bit too much driving at the beginning, but it was well signposted.
varied landscapes.
Just one change that must have been made since the route was mapped out:
At point 2, it says, "At the end of this, turn right onto the small road descending into the valley. Then turn
then turn left onto the track running alongside the Ru de Bouillon." This path is now blocked, and the GR has been diverted. You must therefore continue along the small road, enter the town, take the second left and you will reach the point where the Ru de Bouillon arrives.

The riverbanks are also undergoing construction work, so you must follow the road on the pavement.
Be careful of flooding, which may obstruct the route.

A superb hike in beautiful weather... We even saw ostriches along the way (point 3)!! A short detour centred on point 4, taking the GR trail to the north-west, allowed us to discover some of the sights of CARNETIN.

hello,
Point 2: At the next T-junction, turn right, then a little further on, turn left onto a path marked GR®.
there was a path on the left, but it was not marked. The path on the right, however, was marked
