Description of the walk

Parking is available at the Aire de la Friche, Rue Lenôtre in Anet.

(S/E) From the car park, follow the red and white GR® 22 markings on the left towards the playground and football pitches, then turn right into Rue André Boxhorn. Walk past the Collège Mozart.

(1) At the right-hand bend (Boulevard de la Libération), turn left into the street (Chemin des Vignes), passing the cul-de-sac opposite and the entrance to the school on your left. Continue along Chemin des Vignes, which becomes a small path. After 100 m on this path, turn right onto the path that climbs uphill and joins a T-junction.

(2) Turn right (^GR®22) and reach the D21 at elevation 99. Cross it carefully and continue along the path opposite. At the edge of the forest, turn left and descend towards the village of Boncourt.

(3) Leave the GR®22 on your left towards Paris and continue straight ahead, following the^GR®22variant of the Vallée des Cailles. Before leaving the village, take the street on the right called Chemin des Coutumes.

(4) At the fork, take the path on the right marked in yellow and leave the GR®. Descend the path on the left through the small wood and rejoin the path at the bottom of the valley, a variant of the GR®22.

(5) Follow it to the right, going uphill, and enter the woods. At the crossroads, turn right and walk for about 100 metres, then turn right again to go down to Poteau de l'Entonnoir.

(6) Follow the second lane on the right which climbs back up towards Anet for about 1.8 km, marked in yellow.

(7) Before reaching the edge of the woods, turn right onto the GR®22 and follow it straight ahead to leave the forest. Descend towards Anet via Chemin de la Presse.

(8) Take Boulevard Charles de Gaulle on the right, then cross it to descend to the left towards the church. Pass it and turn right onto Rue Philibert Delorme. At the end of the street, follow Rue Diane de Poitiers on the left. At the roundabout, turn right, pass in front of the castle, then turn right to return to the car park (S/E).

You can avoid Boncourt by going behind the village and returning to the valley path.

A nice little hike, which at least had the merit of introducing me to the Château d'Anet.

The Caille Valley is a beautiful place, ideal for a picnic.

Thank you for sharing.

Between points 5 and 6 (funnel post), there are no more markers (yellow) or traces of a path. Does the path cross the meadow or should you head for the edge of the nearby forest?

I found my way back to point 7 but missed point 6.

I combined this hike with the one called "Boucle de Rouvres" (Rouvres Circular), which also crosses Boncourt, to create a route of about twenty kilometres. So we started in Boncourt, coming from Rouvres.
It was a beautiful autumn day, with good paths and Anet, which is well worth a visit.
Horns blaring, shouts and gunshots near the Entonnoir crossroads. A hunt must have been taking place in the other part of the forest.

A very beautiful hike, with a lovely section through the forest. We then visited the Château d'Anet. A very pleasant day.

Hello again, points 1 and 2, cross the A21 carefully and continue straight ahead, which will take you back to the centre of Anet...

Just that, in our opinion, there was a typo in the route description: after the road that goes uphill... turn right and carefully cross the D... well, yes, you end up back in ANET and not in BONCOURT, which is on the opposite side...

We didn't know which way to turn...

Please share your opinions so we can compare.

A pleasant, easy hike.
The section between 4 and 6 is very pleasant!
From point 6, I took the alternative route... Wide paths with lots of signposts!

A slight hesitation at the start: from the car park, with your back to the castle, follow the red and white markings of the GR® 22 trail to the left...
Suggestion: From the car park, follow the red and white markings of the GR® 22 towards the playground and football pitches...

It might be a good idea to add a link to the Renaissance Interpretation Centre.

Thank you!
