Description of the walk

Start

The hike starts at the Place du Château in Thiers-sur-Thève (Oise).
A shaded car park has been provided.

No signposts

Turn left onto Rue Fontaine du Gué and, at the end, turn right onto the path that leads to a small bridge (1) over a branch of the Thève just before a crossroads. Take the second track on the left and follow it. At the next crossroads (the markings for plot 236 are faintly visible on the trunk of a tree) (2), turn right onto the second track. This will take you to a fork where you will see the ruins of an old bridge on your right (3). Take the track that passes between the remains of the two abutments. Continue straight ahead until you reach the Carrefour du Bu.
(4) When you reach plot 232, turn left onto the path that climbs up to plot 179, then turn right and continue to a star-shaped crossroads (5).

Turn right onto the path that leads to the top of the Butte aux Gens d'Armes (6).
Cross the clearing and take the sandy path downhill in front of you. You will come to the A1 motorway bridge, which you cross to reach the Carrefour des Gens d'Armes, in the centre of which is a signpost (7).
Make sure you note the direction of the Route de la Haute Chaume, which you will follow for about 2.5 km (as there are not many other signs on this section of the route). It is perfectly straight. As you pass, you will see the mark for plot 132 (8) in large green numbers on a white background on your left, then, further on, the mark for plot 141 on your right, well before you reach the Poteau de la Haute Chaume.
Cross the crossroads and, about a hundred metres further on (9) (there is a marker for plot 130 on your left), turn right onto a path and follow it for 800 metres until you reach the Carrefour de l'Ébène, which no longer has a signpost due to ongoing forestry work. You will see theGR® trail marker on the path that cuts across the one you have just followed at a right angle.

GR®1signpost (red and white)

Take theGR® on the left and continue. You will pass Carrefour du Bosquet Rond, where you turn diagonally to the right. TheGR® passes over a hillock; continue to the next one, where there is a nice spot for a picnic in the middle of a pile of rocks (10).
Turn back to return to the Carrefour de l'Ébène and follow the GR®. Further on, you will pass the Poteau Sainte Marguerite and then the Poteau du Merisier and arrive at the Maison Forestière de la Pistole near the A1 motorway bridge (11).
Cross the bridge and take the path immediately on the right, then, after about 100 metres, turn left onto a path that is no longer signposted (12).

No signposts

After about 100 metres, turn left again and after 500 metres you will reach a path markedGR®(13).

GR® signposting (red and white)

Take theGR® on the left and follow it to Rue du Pont Chantrel (14), which will take you back to the car park at Place du Château.

The hike is now complete.

A very pleasant hike through a forest landscape with pine trees, sand and ferns. The route is very easy to follow with the app. The paths seem well maintained. There is little elevation gain. Ideal for a short day or half-day hike.

I like to complain. Too straight, poorly signposted, monotonous, too noisy, too many people, too much sand.
But I'm not going to do that.
Thanks to Visorando and the creator of this route.
We walked the route in early May 2023 and everything went very well. Guidance with the app, map downloaded, super easy. Okay, sure, they cut down the trees and plot 130 is no longer marked .
Point 10 is nice for a picnic, but you have to leave early to get there by noon.
__Seriously, though: let's not be negative. This route offers easy parking and two crossing points over the motorway. Between these two points, you can do whatever you want, there are plenty of paths. FREE!!!
__What's more, we picked up 3 kg of mushrooms (yes, in May) and ate them.
There you go.
Otherwise, following the route, there is a wide variety of trees, few hikers, no difficult terrain, birds, and on a small part of the route, the noise of the motorway.
Thanks again.

A very beautiful hike. It's not easy to write about a hike, but I would advise anyone who, like me, is unsure about which path to take to download the Visorando app onto their mobile phone. It's ideal. Thank you again for this magnificent hike

A very pleasant outing in the forest. Fairly easy.
The first part up to the Butte des Gens d'Armes could be shortened to avoid the long straight stretches of bridle paths.
It's a shame about the almost constant noise from the A1 motorway.

A pleasant route through the Ermenonville forest.
The signposting isn't great, even with the description and map, but we managed to find it.
A pleasant walk in the sunshine.

A very pleasant route with a beautiful variety of vegetation; the "Mediterranean" section is particularly remarkable (sandy terrain and pine trees). The description is fairly accurate and only causes a few minor hesitations. Flat terrain with no particular difficulties.

Pleasant hike. Luckily we had the GPX track because the signposting is often lacking. However, the Visorando directions are reliable and useful.
Nice spot for a picnic!

A very beautiful hike under sunny skies. No problems finding your way with the directions, just be careful because some of the plot numbers are almost illegible. The Ermenonville Forest is magnificent. I would definitely recommend this hike. Thank you for the description.

The route was completed under beautiful May sunshine with GPS on Visorando, and we had no problems finding our way.

The first part, from the start to point 4, is the least enjoyable, but after that we rode through this magnificent forest, which we rediscovered.

It's a shame that at point 9 or 10 there was no suggestion to take a detour to the memorial to the 1974 plane crash.

To extend the route, at point 9, we picked up the "un grand tour en forêt d'Ermenonville" walk and joined points 7 to 11, then 3 and 4 to return to point 10 of the walk, which gave us a total loop of just over 22 km.

Thank you for these trails.

A magnificent forest trail with no difficult sections during this wet period, as the paths are often sandy. The only difficulty is that the plot numbers are either missing (trees have been felled) or illegible.
We found lots of mushrooms (boletus mushrooms) along the path.

A landscape of well-maintained forests and others that are not. I still wonder why the two bridges that can be seen were built, as they are old and have never been connected to any network!

a very nice hike today, Thursday 15 August. The forests are very varied: deciduous trees and pines; the undergrowth is very pleasant. We only came across about ten people. Thanks for the picnic spot, which allowed us to take a little nap lying on the rocks with the pine trees standing out against the blue sky!
