Les Buttes de Rosne by Sarah Bernhardt

A very bucolic walk in the heights of the French Vexin, passing close to the highest point in the Ile-de-France region. A beautiful forest to cross until you reach the house that was once inhabited by Sarah Bernhardt. Return through the fields across a beautiful landscape at the edge of Picardy.

Description of the walk

Parking is available in front of the town hall in Neuville Bosc.

(S/E) Go down Chemin de la Fontaine and immediately turn right onto Rue Antoine Havard towards the church. Continue downhill at the foot of the church, following the road until the first crossroads.

(1) Turn right onto Rue des Grouettes after the bus shelter, go up the road and enter Cresnes. Pass the first crossroads with Chemin des Bruyères, where theGR®11arrives.

(2) Look for the red and whiteGR®11signpost and follow it to the right at the next junction, into Chemin des Buttes. At the fork that follows immediately, turn right and continue along Chemin des Buttes, which heads south. The road ends in a wide, stony path, which climbs very steeply after a while.

(3) At the top of the path, leave theGR®11, which branches off to the right, and continue straight ahead on the path through the forest. Many paths that lead to this track are blocked by chains as they are private and therefore off-limits. Stay on the main track, which is quite wide. After about 15 minutes of walking, you will see large rhododendron bushes in the forest and a stone wall on your left. You will arrive at a hamlet of a few houses.

(4) Turn left, go through the wooden gate and continue for about ten metres. The house on your left, at the corner with the tarmac road, is Sarah Bernhardt's house. It is private and unfortunately not open to visitors.
Turn around and go back through the wooden gate. Take the path in front of you. After about 100 metres, it descends quite steeply. It is distinctive because it is sandy and deeply carved by water runoff when it rains. The forest eventually thins out, and on the left-hand side you will see pastures with large trees. Continue along the path until you come to a stream. Follow it along the left-hand side, then cross it. Head back up towards Chavençon. The path runs alongside pastures, then follows a large stone wall and ends at a paved road.

(5) Cross Chavençon straight ahead, ignoring the streets and paths that come up, until you reach a crossroads at the foot of the church. There, turn right. Further on, at a fork after a pond, take the road on the right. Follow the road until you find a path on the right blocked by a wooden barrier that enters the forest.

(6) Take this path and follow it until you come to another fairly wide path coming from the left. Take this path to the right and climb up under the pine trees. Follow the path which, after about 200 metres, turns left. Continue to the crossroads called "La Croisette", ignoring all the paths, which are often private, that branch off to the sides. At La Croisette, you will find directions on wooden signs. Follow the main path towards Neuville Bosc (north) and go straight down a very steep path that ends after the water tower on a fairly wide, flatter road. After walking for 5 minutes, the forest thins out and you will see a beautiful house on your right. Continue to the junction with the tarmac road.

(7) At this crossroads, take the path that runs along the left side of the large house opposite you. After about 50 metres, it will come out into fields with a beautiful view. Continue along the path, cross the D508 and continue on the fairly wide path. It continues straight ahead. 200 metres further on, the path turns left and in this bend, a narrower path goes straight ahead. Take this road, which is directly opposite the main road you have just left. It runs alongside some retention basins and then hedges, ending at the corner of a road in the middle of the hamlet of Petit Alleré.

(8) Take Rue de la Cote Mignonne on the right, then turn right again at the crossroads and take Rue du Pré Nicolas Roux, which crosses the D508 towards Cresnes. At the first crossroads (1), turn right and head up towards the church and then the town hall (S/E).

Notes

No water sources. In autumn and winter, bring boots as some paths are muddy.

Worth a visit

In autumn, you can find delicious chestnuts in the forest to enjoy on your way back. As you leave the forest, discover the panoramic view of the Picardy region. On your return, enjoy a superb view of the church of Neuville Bosc, standing on a promontory and surrounded by tall pine trees.

A walk with quite a few hills, you go up and down constantly, but there's one particularly muddy section where we had to find branches to cross a path in the edge of the forest that was completely impassable due to the mud. Otherwise, the walk is varied and takes you past the house of Sarah Bernhardt, who loved to gaze at the stars from the roof of her house...
We used the app with geolocation and it was very easy to find our way around. I highly recommend it!

A slow start, but then the forest opens up before you... In this part of the Oise, heavily fortified hunting reserves are so numerous that, over a 10 km stretch, it feels like only the path itself is not private property. Elsewhere, there are makeshift watchtowers and illegal, partially destroyed huts. The hunters are on their turf, and I can't even imagine hiking in this shooting range after September. It's a shame, because the forest is very beautiful and lush. It must be home to animals that are now too hunted to show themselves. At the end of the trail, a bold pheasant looks at us cockily, coos, then disappears into the alfalfa.
We completed the walk in scorching heat, but the forest was cool. Bring binoculars to Chavençon...

A lovely walk to do at this time of year to admire the rhododendrons in bloom. It's rare to see so many. The walk through the forest is really nice.

A very diverse circuit, best done in autumn and spring as there are many sections under trees. A few muddy sections but overall an easy route even in wet weather.

Superb and varied route (forests, fields, old villages). Suitable for winter as it is easy and fairly short.

Excellent hike with superb views, varied terrain and atmosphere, and a nice little climb.
Two minor details to update the description:
- at point (4), the barrier is metal.
- At point (6), the barrier has fallen to the ground. It cannot be seen from the road but it is still there :-)

On the last section, you can take an optional detour to 'La Pierre aux Coqs', where you will find the remains of a Neolithic menhir (+1.3 km).
From the point (8), return to Le Grand Alleré via the road. Immediately turn right onto the Ruelle des Vignes, which heads east and becomes a path. At altitude 114, the path turns at a right angle south towards La Pierre aux Coqs, then intersects with the GR11. From there, you can reach (S/E) by following the path westwards, then the road that runs alongside the cemetery.

Mainly forest trail. Some pretty spots but not much of interest to see... Few hikers despite exceptional weather.

Great hike with varied landscapes. A little elevation gain, which allows you to work up a light sweat.
The advantage of this hike is that it consists of two loops, one 8 km long and the other 2 km, which means that the route can be adapted to suit everyone.

We had a lovely walk on 23 May 2022. The rhododendrons were in bloom... stunning for over 300 metres along the path leading to Sarah Bernhard's house. Lots of woods, an easy walk.
For a group of 15 like us, I highly recommend starting from Chavençon, parking at the church in Neuville Bosc. There are no parking spaces there, so we actually started from marker 5 and then 6-7-8-1-2-3-4 and returned to 5.
Enjoy the hike!
