Description of the walk

The starting point is the car park at the Dauphine crossroads.
It can be reached via the Chemin des 8 Routes à la Belle Côte in the commune of Perdreauville.

(S/E) From the car park, head north towards the forest via Route Dauphine. After about 50 metres, turn left onto Route Sans Peur. Continue straight ahead (north-west) and pass Carrefour Berri. Continue straight ahead, ignoring a path on the left, then one on the right, until you reach Carrefour Bayard (the junction of Route Sans Peur and Route Madame).

(1) Take the path on the left that descends to a T-junction. Then turn left (yellow markings). Wind your way through the forest and cross the limestone lawns (information panel). Ignore a path on the right and, at the next fork, turn right (yellow markings). Continue, ignoring a path on the left and then a path on the right.

(2) When you reach a crossroads, turn left onto theGR®26(red and white markings) towards Carrefour Dauphine (wooden sign). At the next crossroads, continue on theGR® opposite.

(3) At Mare du Désert, turn right (yellow markings). Further on, go through a forest gate and continue to the D114. Cross the road and follow it to the right. Then take the first left, Rue du Poirier Godard. At the end, turn right and continue for about 30 metres.

(4) At the next crossroads, turn left (yellow markings). Cross the Ru de la Vallée and you will come to a road: follow it to the right towards Boissy-Mauvoisin.

(5) At the stop sign, cross Rue de la Grande Mare and immediately take the path on the left (east). At the fork, continue straight ahead. Turn right onto the path to reach a road (Rue du Moulin de Bléry). Follow this road to the left for 250 metres.

(6) Take a path on the left. After a right-hand bend, join a road and turn right towards the hamlet of Bléry. Cross the hamlet via Rue de la Marnière.

(7) At the junction with Rue du Moulin de Bléry, turn left. At the fork immediately ahead, continue right towards Ménerville.

(8) Before the railway bridge, take a path on the left (metal barriers) that leads to a road. Then turn right towards Vallée de la Taupe (road sign). Continue straight on towards Apremont for about 2km, ignoring the turnings on either side.

(9) After the forest barrier, turn left onto Rue du Petit Clos and then left again onto Rue du Manoir.

(10) Take the path behind a wash house. At the next fork, bear right (red and white markings) and go uphill. After walking alongside a field, you will arrive at the D114.

(11) Follow the road to the left carefully for about 300 metres.

(12) At the entrance to the hamlet, immediately turn left onto Sente Poirier Frères Jacques. At the T-junction, turn right onto Chemin du Moulin de la Taupe.

(13) At the next junction, turn left onto Rue de la Cour aux Huans. This road winds its way to a T-junction.

(14) Cross the Route de Boissy and head left. After about 80 metres, turn right onto Sente du Garde-Champêtre. At the end, first turn left then right to cross the road and take Chemin des 8 Routes, which leads to Carrefour Dauphine (S/E).

A beautiful hike with lots of variety in the landscape, little tarmac, a well-marked route, and a wonderful discovery with the Tauoe Valley.
Thanks to the author.

I was delighted to discover this part of the Ile de France region between Vexin and Rambouillet, which I knew nothing about.
Thank you.

A long and beautiful walk indeed! It's a playground near my home.
Delays! Big problem on the J line in Mantois.
And you weren't able to stroll along the banks of the Seine while you waited... like you did in Bonnières!

We left Rosny station and started the hike in Apremont, then continued along the route called "the ruins of Beurons Castle and the Mademoiselle oak tree" to complete a large circular hike in a day.
It was a hilly hike on good paths under a hot sun, which made us appreciate the forest sections but less so the crossings through fields.
Beautiful scenery, a bit of heritage and no one else on the paths – everything we needed for a great day, except for the 45-minute delay on the train home.

A pleasant hike, starting with a walk through the beautiful Rosny forest with its magnificent limestone grasslands bathed in sunshine. The stretch through the Taupe Valley is quite impressive. A little too much walking along the D114, which is quite busy with motorists in a hurry.
