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).
