Armed boundary markers in the Rambouillet Forest

On the edge of the Rambouillet National Forest, the Old Road from Nogent-le-Roy to Montfort-l'Amaury is marked by boundary stones dating from the Ancien Régime and decorated with fleurs-de-lis. This short hike, which requires a good sense of direction, starts in the heart of the forest in search of these boundary stones and ends in a rural setting.

Description of the walk

Start at Les Haizettes, at the crossroads with a wayside shrine and a bus stop. There are several parking options:
- Along the wide forest track heading west (taking care not to block the forest gates).
- In a small car park opposite No. 39 Route des Haizettes (the road that branches off to the left when facing the oratory).
- In another small car park further along the same road (at the name "Les Haizettes" on the 1:25,000 map). Take the road just behind the car park and follow it to the left (south).

(S/E) Opposite the oratory, turn right and take a wide forest track. Turn immediately left, go through a forest gate and take the wide grassy track running south-south-east parallel to Route des Haizettes. This track approaches the road (small car park mentioned above) and then turns right. Go through a forest gate and continue straight ahead on the D112 road. After about 150 metres, before the road descends, turn left onto Route les Haysettes au Parc d'en Haut (sign; note the difference in spelling from Haizettes). Go through another forest gate and follow a small paved road closed to motor vehicles heading south.

(1) At the crossroads (signpost), take the first path on the left (north-east). Be careful, this path is not very well marked; it starts at the foot (left side) of a tree with two thin twin trunks. Follow this grassy path to the corner of a fence at the foot of which you will find the first signpost.

(2) Continue along the path that branches off from the fence and turn right (east-southeast, azimuth 120 to be precise). Immediately ignore a path on the left (northeast), pass at the foot of a group of three birch trees on the right and continue east-southeast on the grassy path. After a wet section, you will come to a wider path. Keep heading east-southeast, crossing several small drainage ditches and a few forest tracks.

(3) At the T-junction at the edge of forest plots nos. 17 and 20, turn left onto a wide grassy path. Follow this path between two beautiful forests. Shortly before a wooden gate, ignore a vague path on the right and continue to the gate marking the boundary between the Rambouillet State Forest and the Domaine de la Mornaie (private property).

(4) Turn right and follow the fence on your left.
N.B. There are actually two parallel paths... It is recommended to follow the one closest to the fence, even if in places it is poorly marked and resembles a ditch: on the one hand, this is where the boundary markers are located and, on the other hand, the furthest path disappears into the vegetation beyond forest plot no. 12.
So keep heading north-east, ignoring the paths on the right, as the barrier is a good landmark that you should keep in sight. At plot no. 12, the wooden barrier gives way to a barbed wire fence. At the corner of this fence (boundary stone), leave it on your left and continue for about 50 metres, following vague tracks. Turn right, cross a "plank" bordered by small ditches and come out onto a grassy path.

(5) Follow this path on the left (north): this is the Route du Grand Veneur, which leads to the oak tree of the same name. Go through a forest gate and continue straight ahead on a wider path between two fences, first through the forest and then lined with a row of trees and between meadows.

(6) At the end of this path, follow the D112 road to the left. Just before entering the forest again, leave the road and turn right onto a path that starts between two fences (sign saying "Décharge interdite" [No dumping]). Go downhill, curving to the right. At the bottom of the descent, turn left onto a grassy path and follow a meadow on your right. Then climb between the hedge or fence on your left and the fields on your right, ignoring a path coming from the right.

(7) At the next intersection, turn left and continue for about 400 metres to enjoy a view of the Château de la Mormaire and its grounds. Retrace your steps.

(7) Turn left (west) onto the main road. Ignore a path leading down to the right towards a wood and continue straight ahead towards some houses. The road gives way to a tarmac lane; follow this to the crossroads with the oratory (S/E).

Notes

Hiking boots are required. Avoid rainy periods, as the forest trail can be wet.

There are no water sources or shops along the route.

Warning:
Some sections of the forest, between (1) and (3) and between (4) and (5), are on poorly marked paths, overgrown with grass or littered with branches, or even on vague trails in the undergrowth. This route requires a good sense of direction. For these two reasons, the hike has been classified as Moderate rather than Easy, as its modest distance might have justified.

The entire route is unmarked. A 1:25,000 map is essential (at least the one accompanying this description). A compass may also be useful.

Hike completed by the author on 4 October 2016.

Worth a visit

- Beautiful forests, fern undergrowth.
- Chêne du Grand Veneur, between (5) and (6). A tree with a remarkable trunk diameter, but apparently in poor health...
- Armed boundary markers, between (1) and (5). These markers were used to delimit the royal domain, the Forest of Rambouillet, from a private estate, that of La Mormaire.
- Manoir de la Mormaire, on the way there and back from (7).
- Oratory of Les Haizettes (S/E).

Avoid at this time of year, as the paths are very muddy. I really struggled to complete this hike.
I even lost my way while looking for point 5, which is submerged under water.
I didn't like the fact that the route takes you along two departmental roads.
The second section of road has virtually no hard shoulder, forcing you to walk on the carriageway.

A pleasant hike with no difficulty. The detour to the castle is definitely worth it. We did this hike in the late afternoon.

Easy to find starting point.
Pleasant and refreshing walk in summer as most of it is in the forest.
Nice detour to the castle.

I also extended the route a little by starting from Gambaiseuil and returning on the other side of the D112.
It's very muddy in February, and the path near the boundary markers (or the river in some places) is littered with fallen trees.
Thanks for the route idea.

Hello,
Given the current health situation (in the Paris region) and weather conditions, as well as my age (63), I have been unable to go on the hikes I downloaded. As soon as the weather improves, I fully intend to do them.
I am happy to answer any questions you may have on your website, which I find very useful for planning hikes, but rather heavy going compared to other similar sites. Part of my professional life involved organising half-day hikes for senior citizens.
Best regards

I used a large part of the route for a longer hike (La Queue-Grosrouvre-Gambaiseul-Orgerus) and I (along with the group I was leading) really enjoyed the paths we took, the panoramic view of the castle and the small signposts bearing coats of arms. I mentioned that I had borrowed the idea from a fellow hiker, whom I thank very much.

--Hike with no signposts but very well described, so with a compass there's no problem. Pleasant route with no difficulties. Beautiful stone markers and the little detour to the castle is worth a look

Well, I did this walk at the end of winter and I wasn't very focused... so, on the one hand, the scenery wasn't at its best, and on the other, I didn't spot a single one of the armoured boundary stones. But if you do it in spring and take the time to look for these famous stones, it should be a nice little hike!
