Large loop from Maisons Laffite to the Étang du Corra

This circuit connects some notable points in the northern part of the Saint Germain forest: a riding school and former theatre, a hunting lodge, a pond, a former shooting range and a 10-pointed star (crossroads). There are no particular difficulties, except for watching out for horse riders, who are numerous at weekends (horses have right of way).

Description of the walk

Park in the streets near the Caves du Nord (horse riding centre located at the end of the "Albine" lane opposite the Château de Maisons Laffite).

(S/E) Head to the "Porte du Nord", a stone arch on the right (northeast) of the Caves du Nord riding school, along the Gallieni military camp. Go under the arch, follow the military camp and the road, heading northwest.

(1) At the end of the camp, turn right onto Route du Belvédère (signposted "Fromainville - stand de tir"). Follow this road for about 40 metres and take the first small path on the left that winds its way into the forest. Pass two crossroads and then follow the remains of a blockhouse on your left ("abri" on the map).

(2) At a T-junction, turn right (north-west).

(3) At the crossroads, go straight ahead. Pass two more crossroads, continue north-west and you will arrive at the Étoile du dessus de la Muette.

(4) Then turn sharply left into thesecond road, Route de la Muette, which is a wide track. Note the Pavillon de la Muette at the end, which is your destination. Go around the pavilion on the right until you reach the tarmac road that leads to the entrance gate of the pavilion (viewpoint).

(5) At the gate, turn back and take the first path on the left (Route d'Andresy; wide track;GRP® sign at the start of the track). Continue straight ahead and, after two crossroads, you will arrive at the Étoile de la Sablonnière.

(6) Take thesecond (small) road on the right, heading north-northwest. Pass two crossroads and you will arrive at a crossroads.

(7) Take thesecond path on the left, which descends north-west through a pine forest.

(8) At Étoile Sainte-Honorine, take thethird wide road on the left (route du Corra) and you will immediately reach the Étang du Corra at the "l'île aux oiseaux" picnic area. Walk around the pond (the route on the map is counterclockwise; there are several picnic areas around the pond). Return to the "l'île aux oiseaux" picnic area, take the Route du Corra in the opposite direction for 100 metres until you reach the Étoile Sainte-Honorine.

(8) At the star, take the first path on the left (north) and follow the forest wall. Turn right and follow the wall until you reach a gap in the wall that allows you to pass through the Paris-London cycle path (the cycle path sign has been removed).

(9) Cross the cycle path and, at the fork immediately ahead, take the path on the right, the Route de Madame. Continue straight ahead on this pleasant forest path and, after four crossroads, you will arrive at the Étoile de Madame.

(10) Cross this crossroads and take thesecond path on the left. You will arrive at the Étoile de Villeroy, at the crossroads of two major bridle paths. Take thethird path on the right, which heads east-northeast between the Villeroy and Monteclar roads. Wind your way through the undergrowth until you reach a track (the Route d'Aryen).

(11) Cross the intersection and continue south-east on the Route d'Aryen.

(12) After about 500m, at thesecond intersection, turn left onto the old Route d'Artois and reach the fence of a regeneration plot. At the gate, turn right to follow the fence and the path that runs along the plot. You will arrive at the entrance to a large natural lawn (former shooting range; busy with families at weekends).

(13) At the corner of the fence and the lawn, take thefirst path on the right (south). Follow the Étoile d'Herblay car park until you reach a crossroads. Then take thesecond path on the right (west), opposite the road coming from Achères and Fromainville. At the next crossroads, stay on the path that curves to the left (south-west).

(14) At the first junction after the crossroads (about 300 metres after the bend), take the (small) path on the right. At the next crossroads, take the Route du Bout du Monde (second path on the left).

(15) At the Étoile du Bout du Monde, take thethird road on the left, the Route de Villeroy. Cross a bridle path and continue along the road that climbs up a hill.

(3) At the crossroads just before the top of the hill, turn left onto a path that you took in the opposite direction on the way there.
(see alternative route).

(2) At the next intersection, continue straight ahead and join the Étoile des Pétrons (car park). Continue straight ahead along the road, heading south-east.

(1) At the corner of the military camp, continue straight ahead to the North Gate (S/E).

Notes

This circuit can be easily completed by Nordic walking (allow 2½ hours) or on foot.

- Free parking is available in the streets adjacent to the Caves du Nord. Please observe the park's traffic rules (30 km/h - no parking on the lawns).

- Maisons Laffite is the "horse capital": there are numerous bridle paths on the eastern half of the circuit, with priority given to horse riders. Please note: horses are skittish animals, so remain calm and do not move your walking sticks.

- Apart from theGRP® markings (yellow and red, well maintained), the markings for short hiking trails (orange markings, purple lines on the map) are random and sometimes replaced by horse trails: rely on the map and your compass.

- Where indicated, the forest plot numbers, usually marked in black on a white background on trees at the intersection of plots, are useful and can be found on the IGN map.

- There are no shelters or water sources along the route.

- There is a viewpoint and a picnic area halfway along the route, at the end of the Etang du Corra circuit.

- This circuit crosses several car parks, which are often full at weekends and during the summer.

There is a variation at the end of the circuit from the Étoile du Bout du Monde, waypoint (15).

(15) At the Étoile du Bout du Monde, take thethird path on the left, the Route de Villeroy. Cross a bridle path and continue along the path that climbs up a hill.
At the crossroads (3), continue along the path to the top of the hill and to the road, then turn left onto the track that runs alongside the road and joins the Etoile des Pétrons (car park): this path is not shown on the IGN map, but it is marked on OpenStreetMap.
Continue straight ahead along the road, heading south-east.
(1) At the corner of the military camp, continue straight ahead to the North Gate (S/E).

Worth a visit

- The north-west main façade (facing the Caves du Nord) of the Château de Maisons Laffite, which has been beautifully restored.
- les Caves du Nord: riding school, former theatre and a pavilion built by Mansard (on the right as you head towards the north gate).
- The Pavillon de la Muette, a former hunting lodge.
- The Étang du Corra, a former quarry and nature reserve for birds (which come to beg for bread on the "forest beach" near the Corra car park).
- The forest enclosure wall, remains of the royal enclosure wall (former forest kept for the king's hunts). Behind the wall are the agricultural spreading fields of the Achères wastewater treatment plant.
- The shooting range, now disused, which was used for military training by the Gallieni camp (made famous by one of its occupants, General de Villiers, who used to go jogging in the forest).
- The Étoile du Bout du Monde (Star at the End of the World) and its signpost, the only 10-pointed star (5 roads) in the Saint-Germain forest (unfortunately, the signpost is in poor condition and three directional signs are missing).

Hello, thank you very much for this beautiful hike on Sunday, 24 August 2025. Flat terrain and a very pleasant forest trail. Also worth noting is the beautiful Doulton house at 30 Avenue Pascal, just before the entrance to the forest. The description is not very precise from point 12 onwards. I got lost in the explanations and at the crossroads (small crossroads with paths - large crossroads...), (I didn't see any fencing around the regeneration area, but is it still there? And there was no sign at the star at the end of the world), it would be helpful to indicate the forest plot numbers, for example, and there was no sign at all at the star at the end of the world... luckily, I had brought a map of the forest with plot numbers, so I was able to find the description at point 2 (étoile des pétrons), but it was still a bit of a hassle. The walk around the lake is nice, but there is only one picnic table on the entire route (not several as indicated) and, as someone has already pointed out, unfortunately when you approach the west side of the Corra lake, there is a car park... and rubbish everywhere!
Thanks anyway

An easy and pleasant route through the forest. It's worth stopping for a picnic around the Corra pond.
The town of Maisons Laffitte with its nearby castle is an interesting place to end the hike.
The new version of Visorando superimposes our suggested route (in blue) onto the proposed route (in red) as we progress. This is useful, but be careful: it uses a lot of battery power and I had to use a spare battery.

A useful circuit for getting back into shape, the flat terrain is broken up by the Corra pond. There are lots of geese, swans, ducks and moorhens there... On this particular day, we had the unlikely sight of a model wearing nothing but her birthday suit entering the water at 7°C for a photo shoot. This early spring also marked the return of jays and other corvids... a treat for the ears. The end of the route was punctuated by a stop at one of the bakeries in Maisons Lafittte... another treat.

we started at the Château de Maisons Lafitte after visiting it (free admission on thefirst Sunday of the month, but not all year round)
A very pleasant walk and, despite the rain the previous week, there was little mud and the paths are quite wide

A pleasant, easy walk (flat route), almost entirely in the forest, which makes it a little monotonous. Fortunately, the walk around the lake is very pretty and offers a nice break.

A lovely walk in the woods, nicely shaded which was very welcome. Beautiful views of the Corra lake with lots of birds. It's a shame that the area around the lake by the road is so dirty (rubbish)... It's worth taking the opportunity to visit the Château de Maisons Laffite. A lovely, easy walk and a real change of scenery so close to Paris.

As always, we downloaded the map and used GPS navigation. Easy.
We did the route on Sunday, setting off at 11 a.m. There were quite a few people around the lake, with barbecues despite the ban.
The temperature was bearable, even though part of the route was in the sun and the rest was in the forest. Not sure it would be doable in the middle of summer.
Varied landscapes, a squirrel and a woodpecker feeding its young, lots of birds. We liked it.
Only one horse and a few bikes. We liked it.
Back in Maisons-Lafitte, a Perrier and a 50cl beer on the terrace for €13, which we didn't like.

Very beautiful route, but as there are no road names or signposts, you have to keep count of the intersections. And after the Aryen road at the end, it gets less easy. We had to ask for directions to find our vehicle.

Hello @Claudber78, you must have cut a lot, because I measured 13.2 km and I even took a few shortcuts.

This hike offers a very varied route, with sections through woodland, over autumn leaves, more open sections on wide paths, and a tour of the lake.

By cutting across at two or three points, I measured the route at 13.2 km, which I completed in 2 hours and 20 minutes.

If you are near Achères/Poissy or Conflans, there is no need to go to the starting point at Maison Laffitte. The most direct route is to start the walk at the car park at the Corra pond, which is easily accessible via the N184.

The paths are very busy with mountain bikes, so you have to move to the side to let them pass.

A pleasant hike so close to Paris.
Easy to reach from the station (which adds a few kilometres), take advantage of the footbridge to cross the tracks straight away and get to the right side.
Didn't use the description, the GPS track is sufficient.
Lots of pleasant detours to avoid the busiest paths.
A bit crowded around the lake, but for the rest of the route, just a few mountain bikes.

An easy walk in the forest. Not many people out on this Thursday afternoon. A bit of noise north of the pond. At point 14, I turned left to head for the castle. It's pretty much straight through the residential area.
