La Mare aux Canes and the forest trails of Saint-Germain-en-Laye

A pleasant circuit entirely through the woods in the Saint-Germain-en-Laye National Forest. Enjoyable in all seasons except when it rains. Beautiful oak and beech forests, a discovery trail, and a small pond (the duck pond) halfway along the route. No particular difficulty, except for paying attention to the frequent changes in direction. Be careful in autumn and winter, as some paths are difficult to see under the leaves. Visitor numbers: see practical information.

Description of the walk

Park in the car park at the exit of Maisons-Laffitte, on the Route de Poissy, opposite the shopping centre (on the right before the last traffic lights, just after the Maisons-Laffitte exit sign).

(S/E) Take the path that starts at the ONF sign and goes into the forest, heading west, along the road. At the first crossroads, go straight on until you reach a second crossroads.

(1) Turn left onto a gravel path. Come out onto the D308 and follow it to the right for about 20 metres. Then cross the road in two stages, using the central reservation (caution: dangerous road crossing). Return to the path (signposted Route de Brancas) and follow it straight ahead to the south-west. Cross a diagonal path and then a bridleway, continuing for about 150 metres.

(2) Take the first forest path on the right (west) after the bridle path. Walk through beautiful oak and beech forests and cross two paths. At the next intersection (Y-junction), turn left.

(3) 150 metres after the intersection, you will come to a bridle path (the Bourbon road): follow it to the right (do not take theGRP® which crosses and heads south). Immediately afterwards (about ten metres after the junction), take the first path on the left (south-west) between a large oak tree markedGR® and an isolated chestnut tree (path marked Route de Mornay on the map). At the next junction, continue straight ahead.

(4) Cross Avenue de la Muette (wide bridle path) and take the first forest path on the right (due west) (do not continue along Route de Mornay, signposted). Cross Route du Maître Particulier, then a footpath.

(5) The path then turns south-west into a regeneration forest clearing (this path is no longer marked on the map). Join Route Notre-Dame du Bon Secours (sign) at the edge of the clearing. Immediately cross a sloping path, continuing straight ahead, due south (muddy in wet weather), and continue straight ahead, ignoring the paths branching off to the sides.

(6) At the Étoile du Bon Secours (oratory perched on a large oak tree), take the second path on the left (northeast), which is Route de Vaux (sign). At the next crossroads, the Étoile de Lamark, take the first path on the right, which is Route Verte (sign on the path after the crossroads), heading due south. Cross a bridle path, walk alongside a pond on your left and another on your right.

At the junction with Route du Buisson Richard (bench), you will see a signpost inviting you to continue straight ahead: this is the start of the La Salamandre discovery trail, which you will follow in a loop until you return. Follow the marked trail south. After about 250 metres, turn left and descend to a clearing, Place du Val (car park on the left).

(7) Walk along the clearing on the right, turn onto the second path on the right (south-west direction - gravel path), still following the signs for the Sentier de la Salamandre. Cross a path and, at the next junction, turn right (salamander sign).

(8) In the undergrowth halfway up the hill, don't miss the start of the path on the left, marked by a salamander sign. The Sentier de la Salamandre winds its way, crossing other paths, so follow the signs carefully. Cross a bridle path and, further on, you will reach the Mare aux Canes (picnic benches - you can walk around the pond, keeping an eye on the arrival point).

(9) Leave the Mare aux Canes by following the Salamander signs (damaged marker) (if you have walked around the pond, the start is on the left just before the path you came in on). Wind your way through the undergrowth. Come out onto a path and follow it to the right. Cross a bridle path and reach the Étoile d'Actéon.

(10) At the star, take the second path on the left (Route du Buisson Richard) and immediately after, take the small path on the left indicated by the Salamandre sign (the arrow is not very visible, marker in the brambles). Follow the path to the marker at the foot of a large oak tree, after the sign indicating the age of the trees, and just before you reach the bench and a crossroads you passed earlier.

(11) Leave the Salamandre signpost by taking a path (not shown on the map) that branches off to the left and in the opposite direction to the arrow at the foot of the large oak tree. Cross the undergrowth on this pleasant but poorly marked path, heading generally north-west. Please note that this path disappears under the leaves in autumn and winter: If in doubt, see the alternative route in the practical information section. Turn left at the first fork, go around a hollow on the right (dry or filled with water depending on the season) and continue through an undergrowth of oak trees marked with white paint. Join the Route Notre-Dame du Bon Secours and follow it to the right.

(6) Cross the Étoile du Bon-Secours crossroads and continue along Route Notre-Dame-du-Bon-Secours (fourth road on the right, heading north). At the next crossroads, Étoile de Mornay, take the second road on the right, Route de Mornay. At the next crossroads, Étoile du Maître Particulier, take the second road on the right, Route de la Grille Royale (south-east), and continue for about 80 metres.

(12) Take the first forest road on the left. (GRP® marker, red and yellow, not very visible, 20m inside). Cross Avenue de la Muette and continue along theGRP®, crossing several other roads (markings and tricky passage due to forest clearing: keep to the general direction and follow the GPS). Return to Route de Bourbon.

(3) Cross opposite and take the path you came on (leave theGRP®, which continues to the right along the Route de Bourbon). At the fork, turn left (north-northeast). At the crossroads, l'Étoile du Chêne Corbeau, take theGRP® again, third path on the right (northeast). Cross a clearing that is being reforested. Then cross the D308 in two stages (with caution) and continue north on the Route des Ventes de Chatillon. At the first crossroads, turn right (leaving theGRP®) and go straight ahead due east.

(1) Continue straight ahead to reach the car park (S/E).

Notes

Flat, shaded terrain, suitable for Nordic walking (dirt paths - allow 2 hours) and easy for normal walking. If the car park at the start is full, you can park in the shopping centre opposite.

There is a picnic area halfway along the route at Mare aux Canes (benches and pleasant views).

Please note: there are no water points or shelters along the route.

Visitor numbers: Mare aux Canes and the main paths are busy in good weather, but the rest of the route, which follows (small) forest paths, is generally quiet.

A compass or GPS is essential for first-time visitors, as all the paths in this flat forest look the same! Especially as this route favours paths on the main routes.
Note: in autumn and winter, the paths covered with leaves can be more difficult to identify.

Alternative route: at (11), if you are unsure about the route of the small path through the undergrowth, go to the crossroads, follow the Route Verte which starts at the crossroads (5), taking the path immediately to the right of the bench, heading due north, then take the first track on the left to reach the Étoile Notre-Dame-du-Bon-Secours. At the crossroads (6), take the third path on the right, heading due north (Route Notre-Dame-du-Bon-Secours).

A pleasant walk in the woods after a day of work and traffic jams (business trip from Bussy-Saint-Georges to Saint-Germain en Laye).
I preferred to park in the free car park at the swimming pool and walk to the starting point, which didn't add much to the distance and the car park is on the way back. Parking is limited to two hours until 4pm, but as I started my walk at 6pm, there was no time limit.
I'm not from the area... beautiful view of La Défense and the Eiffel Tower in the distance.

It's more of a (long) digestive stroll than a real hike. It involves zigzagging and other back-and-forth movements in a forest that is certainly pleasant, but still a little monotonous. All this under the constant noise of cars, as the forest is surrounded by fairly busy roads. Well, that's it. After that, I think it's difficult to do better in the forest of Saint-Germain-en-Laye.

I don't know why it's marked "Difficulty: Medium", as it's a relatively short "hike" with no technical difficulties and no real elevation changes.

No problem following the route by GPS if you're used to it, but remember to download the maps beforehand for offline use, as I noticed that there was often no network coverage, at least with my mobile operator. I haven't tried the description, but in my opinion, it must be a pain to follow..

A superb hike in dry autumn weather. The colours of the forest are magnificent.
Some noise pollution near the roads, but it's not too distracting.
Highly recommended.

A beautiful forest walk that is safe for the whole family. Keep an eye on your GPS, as it is easy to get lost among the multitude of intersecting paths.

A pleasant walk through the woods that took us 2½ hours at a leisurely pace. There are many crossroads, so you need to check the map frequently if you want to stay on track.

A lovely route entirely through the forest, which is very beautiful in this area. Crossing the main road is a bit difficult on Sunday afternoons.

A beautiful route through the Forest of Saint Germain, where you can get lost at intersections even when using the GPS function on your smartphone...! But there's no need to worry in this forest, as there's always a way to easily find your way back and get back on track!

A very beautiful hike with a few places to picnic, including a table at the Bon Secours star.
The route takes small paths to avoid the main roads, which are a little busier.
The hike passes through a variety of forest landscapes. A must-do!

A very pleasant walk in the forest with its different species of trees. Very well marked.
The only downside: rubbish of all kinds (sic) at the start of the trail.
Be careful when crossing the road (start/finish), but after that it's very peaceful

A beautiful circular walk. Pay close attention to the junctions at points 3 and 6 to ensure you are on the correct path
Otherwise, a really nice route for getting some fresh air in the forest
