Starting point: Bonneuil-sur-Marne Harbour
(S/E) From the esplanade at Sucy-Bonneuil station, head to the right to pass under the road bridge, then turn immediately left onto Avenue de Bonneuil. Take the left-hand lane, which goes uphill and takes you over the railway lines. Take care on the climb up Avenue de Bonneuil and on the bridge. After the bridge, join the cycle path below. At the second roundabout, turn right to enter the business park at the Port of Bonneuil-sur-Marne.
(1) Follow the cycle path for about 1.5 km, running alongside the southern dock until you reach Quai du Raincy, which ends in a dead end. Continue along the Promenade Florence Arthaud, a path reserved for non-motorised traffic, with a narrower section near the Basse Marne sailing club and the canoeing and kayaking club. At this point, you are closest to the Marne, near the entrance and exit points for the port’s barges. In the port area, keep an eye out for vehicles associated with commercial activities. As you approach the water sports clubs, adjust your speed to suit the number of walkers in the area. The route changes scenery and takes on a more bucolic feel as it follows the Marne along the Chemin du Bras du Chapitre. Traffic here is light and slow-moving, and the path ends in a dead end for vehicles. After the barrier, dismount and walk about twenty metres up the path on the left, running parallel to a flight of steps.
(2) Then continue to the right, taking the Passerelle des Uzelles, which leads to Île Sainte-Catherine. Get back on your bike and turn left onto Avenue de la Ferme, then carry on along the Allée Centrale on Île Brise-Pain. At the end of this, turn right onto Rue de l’Écluse. Go under the underpass on Avenue de Verdun, then continue to the right along Allée Centrale. At the end, dismount again to cross the Passerelle Brise-Pain, situated near some hydraulic structures. The route includes a few narrow sections where you’ll need to dismount to cross the footbridges. Watch out for pedestrians, particularly on the footbridges, and adjust your speed in this residential and natural environment.
(3) After the footbridge, turn right onto the cycle path along Rue du Port and Quai de Halage and cycle for about 500 metres.
(4) Turn left and cycle all the way up Avenue Laferrière to where it meets Avenue du Maréchal de Lattre de Tassigny, near the Créteil cemetery.
(5) Take the cycle path that runs alongside the avenue, crosses the A86 and continues along Avenue du Général Leclerc to the entrance to Maisons-Alfort.
(6) Cross at Avenue Sangnier, then turn left into Rue Carnot. 500 metres further on, turn right into Rue Georges Médéric, then continue along the cycle path on Avenue Léon Blum.
(7) At the large junction with Avenue de la République, turn left into Rue Émile Zola, heading towards the town centre. After crossing the railway lines, enter Alfortville via Rue Émile Zola.
(8) 300 metres further on, turn right onto Rue Paul Vaillant-Couturier, the town centre’s main shopping street and thoroughfare. Thisis an urban route, so take care at the successive junctions and when changing lanes. Follow Rue Paul Vaillant-Couturier for its entire length, i.e. 1.8 km. Traffic is restricted to 30 km/h and flows calmly. This route takes you through the town centre, past the town hall and the Church of Notre-Dame d’Alfortville, until you reach the junction with Rue Charles de Gaulle.
(9) Turn left and follow the cycle path to Rue de la Marne, at the end of which you’ll reach the river. There may be pedestrians on the paths leading to the confluence. Pass to the left of the removable barrier to go round the Chinagora Hotel, with its unusual architecture. You will then approach the confluence, where the Marne joins the Seine.
(10) Continue upstream along the Seine via the Quai Blanqui cycle path, which overlooks the river, then take the stabilised gravel track running alongside the aquatic centre and the Parc de l’Île au Cointre. The path is shared with pedestrians in these areas.
(11) Along the way, admire the Port à l’Anglais bridge and the lock system, which bear witness to the historical importance of river navigation. After passing under the bridge, go up the ramp to join the Quai Jean-Baptiste Clément cycle path, which you follow for about 600 metres.
(12) Cross at the pedestrian crossing, then turn left towards Rue de la Carpe. Take care at junctions and when crossing the road. Continue along Rue de Rome, cross Place de l’Europe – which has been turned into a small square – then Rue de Petrograd. Carry on on foot through the tunnel that runs under the railway lines. You must walk through this tunnel with your feet on the ground. At the exit, turn right onto Avenue de la Liberté.
(13) After the roundabout, take Chemin des Mèches, which passes under the A86. Then turn right onto Rue Pasteur Vallery-Radot, which runs alongside the Créteil Courthouse. At the end of the street, cross Route de Choisy and take the small access ramp opposite to reach the Île de Loisirs de Créteil.
(14) Enter the park on the right and stroll along its paths, keeping the lake close by. Following the shared paths, you’ll pass by the Maison de la Nature and the leisure island’s water sports facilities, notably near the wave pool, before reaching the exit on Route de la Pompadour.
(15) Walk up Rue des Batillages, then turn right onto Rue du Canal, which runs alongside a canal. At the end of the street, turn right to pass the Pointe-du-Lac metro station, which is also the departure point for the Câble C1 cable car.
(16) Dismount and walk through this area in front of the station. Take care around stations and when crossing the Bonneuil Bridge. Then join the cycle path which descends alongside the bus lane towards Route de la Pompadour. Continue straight on along this cycle path, then along Avenue Jean Rostand and Avenue Rhin-et-Danube. Cross the Bonneuil Bridge again, which spans the railway lines and takes you down to the Sucy-Bonneuil RER station, the starting point of your route (S/E).
