Departure from Lognes station (RER A).
(S) When you leave the station (there is only one exit), head towards the Étang des Ibis. Go around the pond, keeping it on your right and staying as close to the water as possible.
(1) At the end of the pond, take a small ramp on your left facing a beautiful tree. Continue on the path opposite (northeast). You will come to another path; follow it to the right and cross Rue Gabriel.
Go through the wooden gate (marked Parc du Mandinet) and continue straight ahead. Follow the gravel path along the Étang du Maubuée on your left. Follow the path that turns right and then left, still alongside the pond. At the end of the pond, you will arrive at the crossroads between Rue de la Tour d'Auvergne and Cours des Lacs: turn left.
(2) Follow the Cours des Lacs cycle path, keeping the pond on your left. Pass a restaurant and continue until you reach a small lock on your left.
(3) Leave the cycle path and cross the road to the right. Go through the wooden gate (the cycle path sign is still there) and head towards the Étang des Pêcheurs. Keep it on your left and go under the motorway (D199). Now follow the Étang du Beauregard.
At the end of the pond, continue along the path. You will come to a sort of square with a playground and a wooden rubbish bin in front of you. Take the paved path on the left.
(4) Immediately turn right onto a tarmac path (do not cross the lock). Follow the Étang de l'Écluse on your left. Pass under the Cours de l'Arche Guédon through a small tunnel. You will come out at the Étang de l'Arche, which you will leave on your left. At the end of the pond, continue straight ahead and pass three benches on your right. At the Y-junction after thethird bench, take the left-hand path which descends slightly. At a small junction with a tarmac road, go straight ahead onto the small gravel path which climbs and takes you out of the park at a wooden gate.
(5) Cross Rue Jean Jaurès. Go through the forest gate and follow a narrow path into the woods. Walk through the woods. At the T-junction, turn right. At the next junction, take the path on the left that descends. A few metres further on, you will reach a sloping path with wooden logs. Then turn right and continue through the woods on the path that climbs uphill. At the next T-junction, take the small descent on the left and you will come out onto the Route de Noisiel.
(6) Cross the road and take the path opposite, which immediately turns left. Then turn left again (do not go right towards the canoe and kayak centre). After a small car park on your left, follow a small stream on your right. Follow the path until you see the Marne river! Continue along the path, passing a car park on your left. You will arrive at the former Menier chocolate factory.
(7) Take the footbridge and admire the architecture of the old chocolate factory, which is a listed building. Continue along the factory on your left. Leave the dam on your right. Take another footbridge, which allows you to admire the chocolate factory from the other side and leads you to one of the entrances to Noisiel Park.
(8) Go through a metal gate to enter the park. Take the path on your right along the Marne (info 2019: following the flooding of the Marne in 2018, the path closest to the water is closed). After 500 metres, cross a small wooden bridge and you will come to the large meadow, which you will follow on your left.
(9) Leave the footbridge leading to Chelles or the Vaires-sur-Marne leisure centre on your right. Note: the footbridge is sometimes removed when the Marne is high.
(10) At the end of the park, turn left onto the forest path (before the forest barriers leading to Gournay-sur-Marne). Walk for a good kilometre through the woods. You will come to the large meadow on your left. Stay on the main path until you come to a path on your left at a small passage with two stone blocks on either side of the path.
(11) At the crossroads 10 metres further on, take the path that climbs up to the right. Continue climbing until you reach the top of the park. Do not leave the park through the gate, but turn left. Continue along the path. At the T-junction, turn right until you reach the park's main gate overlooking the large meadow below.
(12) Exit through the main gate of Noisiel Park. Cross the road (D217b) and continue straight ahead along Allée des Bois. Pass over the motorway (D199). Cross the Luzard stream. At the end of Allée des Bois, you will arrive at Noisiel station (RER A) (E).
