- RER - Line A, on the section between Paris and Saint-Germain-en-Laye.

No signage
(S/E) When you leave the station, turn sharply left towards the banks of the Seine and follow Avenue Aristide Briand.
(1) At the end, take thefirst left, a dead-end street that runs parallel to Avenue des Tilleuls. At the end, climb a small staircase and then take the pedestrian path on the railway bridge to cross a branch of the Seine. N.B. This pedestrian path is sufficiently distant from the railway line and is clearly separated from it by a fence.
(2) On the other side, go down a staircase, turn right twice and pass under the railway bridge. Pass through a metal gate and continue straight ahead along a car park. At the stop sign, follow the road to the left, keeping to the right-hand pavement.
(3) Pass under the Pont de Chatou bridge and continue along the road. When the road turns left, continue straight ahead on a gravel path along the Seine and walk past a restaurant on your left. Pass in front of a second restaurant, walk slightly uphill and you will reach a wooden barrier.
(4) Go through the gate and follow the road to the right (Quai Waltier). Stay on the left-hand pavement (there is no pavement on the right) and walk past the EDF research and development centre. Enter Carrières-sur-Seine and reach the entrance to the Île Fleurie golf course car park (gate on the left).
(5) Continue straight ahead and, after about 300 m, you will reach the entrance gate to the golf course.
(6) Continue straight ahead on a wide, stable path. Walk between two hedges, along the golf course on the left and the Seine (barely visible) on the right.
(7) Pass under the A4 motorway bridge. A little further on, pass under a railway bridge and continue through a wooded area. Alternate between very short ascents and descents (view of the Seine on the left) and reach a second railway bridge and an area that looks like wasteland. Beyond the bridge, there is no longer a path and the relatively dense vegetation does not encourage exploration.
(8) Retrace your steps along the stabilised path to the entrance to the golf course.
(6) Continue straight ahead on the road until you reach the wooden barrier near a restaurant.
(4) Continue along the road and pass an art gallery on your left. At the stop sign, continue straight ahead and climb up to the Pont de Chatou bridge.
(9) Turn right and cross a branch of the Seine on the bridge. You will arrive at the foot of Chatou Church.
(10) Then turn left and cross the road using two successive pedestrian crossings. Next, turn right and cross the road again using two successive pedestrian crossings. Turn left, pass a pharmacy on your right and leave the D231 on your left.
(11) Immediately take the next left, Avenue d'Eprémesnil, which turns right straight away. Continue straight ahead and turn right at the stop sign. Take thefirst left, Rue Paul Flamant, and you will immediately reach Chatou station (S/E).
