L'Île Fleurie

This hike is not entirely bucolic, despite the name of this long island, the northern branch of which we explore. After an urban section, we follow a good path through relatively dense vegetation. There are some beautiful views of the Seine, especially in the urban section.

Description of the walk

Starting point and access: Chatou-Croissy station.
- RER - Line A, on the section between Paris and Saint-Germain-en-Laye.
Take exit 2 Rue Labélonye, at the front of the train on the platform in the direction of Paris to Saint-Germain (if arriving in the opposite direction, take the underground passage).

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).

To return home:
- RER - Line A, towards La Défense and Paris (immediate access) or Saint-Germain-en-Laye (take the underground passage).

Notes

Train timetables: consult the Transilien website.

For motorists:
Reach Île Fleurie from the Pont de Chatou bridge on the D991. Several car parks are available:
- Under the bridge itself.
- Between the bridge and the railway bridge (2) further south.
- The Île Fleurie Golf Course car park, which can be accessed on the left at (5). This results in a shorter version of the hike (approximately 5 km), which avoids the road along the EDF research and development centre.

Good sports shoes are sufficient for this route, which runs along tarmac roads or a well-maintained path.

There are no water sources along the route. Restaurants are located near (4).

Warning:
Hikers who do not appreciate tarmac roads or a certain feeling of isolation in a semi-urban environment may wish to refrain from undertaking this hike.

Even if the route seems straightforward, a detailed map is always useful (at least the one accompanying this description).

Worth a visit

Despite the name given to the island, this route is not exactly bucolic. Its interest lies in the strangeness of the place and the vegetation that seems to be given free rein.

The views of the Seine are beautiful but unfortunately quite rare between (5) and (8) due to the vegetation.

In terms of heritage:
- Villa Galatée, between the EDF centre and the golf course car park, a recently restored Art Deco building.
- Chatou Church (17th century).

Hello Fandjo, thank you for your feedback.

I agree with you that it would be useful to be able to loop back to the beginning! I don't think access to the gateway is on the agenda...

A refreshing journey in the middle of nowhere! An opportunity to discover a part of the island that is usually seen from the other side of the Seine. It is unfortunate that there is no access to the Eole footbridge, which would allow for a loop via Carrières or Nanterre instead of a round trip.

I followed this route in March and I must admit that the "Ile Fleurie" side inspired me. But the whole section along the golf course, Villa Galatée and under the motorway is frankly desolate. Especially since the other bank is beautifully landscaped and charming. If I had to do it again, I would do sections 4 to 8 on the other side of the Seine. I rated it "average" because the description gives a bit of a misleading impression, but I hesitated between that and "disappointing". Perhaps it's more pleasant in summer?
On the other hand, the route is flat and very easy.

Half of the route is in an urban area and you have to walk quite a long way before you reach the countryside (at the golf course). Unfortunately, once you're in the countryside, it's no better: the banks of the Seine are of little interest as they are lined with factories.

Hello violetjp1, and thank you for your comments.

Could you specify at which point the route is closed to the public? Have you determined whether this closure is permanent or only for a specific period? Thank you in advance for your information.

Strolling along the banks of the Seine in Paris when the weather is nice is always a real pleasure.

It's something to do again and again. It's so easy.

It could be a lovely walk if the vegetation were cleared from time to time to enjoy the view: we are on the banks of the Seine and we cannot see it!
On the plus side, we only encountered 10 people on this Sunday afternoon, 1 May!

Hello jaco948,

Thank you for your comments! I agree with the description "not unforgettable," but I liked the somewhat wild and solitary aspect.

I've added Villa Galatée to the list of things to see.

Beyond the Pont des Anglais, it's not really that appealing after all... I also read somewhere (but I can't remember where) that the northern tip is a protected site: there are no signs on site indicating that access is prohibited, but perhaps it's better to leave nature alone...

I did this walk the day after the author! It's not an unforgettable route, and you go back the same way you came, which is always less enjoyable than a circular route. But I still enjoyed it, especially when you leave the tarmac and arrive on the dirt track: at this time of year, and in beautiful spring sunshine, I was able to photograph lots of butterflies!
Two comments:
- It would be interesting to mention Villa Galatée at point 6, a superb Art Deco building that has been beautifully restored (by an architectural firm based there).
- The path does not end at point 8 (Pont des Anglais): on the Geoportail satellite view (but not on Google Maps), you can see that it continues to the end of the island, which becomes increasingly narrow, for about another 500 metres. However, I did not venture that far...
