Description of the walk

You can park your car in the square in front of the church in Crêpières or in the surrounding streets.

(S/E) Take the street that runs alongside the church on your left and immediately turn right into Rue du Paradis. At the T-junction that follows, turn left into Rue de l'Enfer (funny combination of streets). Then turn right into Sente des Moulins. Continue straight ahead on the small path which overlooks horse pastures on your right. Follow this path, which curves sharply to the left for about 1 km, until it turns right at a right angle.

(1) Cross the stream via the small stone bridge, then continue straight ahead. Follow the path as it curves to the right for 200 metres.

(2) Take the wide path on the left that climbs slightly.

(3) At the next crossroads, take the first path on the right (GR®1, red and white markings), which climbs up to the plateau. Continue along this path for about 1.5 km, ignoring the paths branching off to the right.

(4) At the junction with a path coming from the left, continue straight ahead, start the descent towards Thiverval and walk alongside the houses. Go down the steps leading to the wash house, then down the Grande Rue. Pass in front of the school and then the church of Thiverval.

(5) Continue up the same street. This route takes you around the Parc de Grignon (AgroParisTech campus marked "Institut National d'Agronomie" on the map, which unfortunately cannot be crossed). Continue straight up Rue de Rougement. This street passes in front of the cemetery and ends at a roundabout.

(6) Cross it and take theGR®1opposite. After about 300 m, at the first fork, follow theGR®1. About 200 m further on, theGR®1branches off to the right. Leave it here and continue straight ahead to Pièce des Vignes (elevation 128).

(7) Then turn left to return to the D119.

(8) Cross the road carefully and go down the hill to Soula. You will have the wall on your left and houses on your right.

(9) At the bottom of the hill, turn right and go up Avenue Lucien Bretignières. At the top of the hill, you will rejoin the D119 road.

(10) Turn left onto it. Continue along the wall of Parc de Grignon for 500 metres.

(11) Turn left onto the tarmac road that goes downhill. Pass by the water treatment plant.

(12) Follow the widest path, which veers to the right, until you reach the last house. Continue along several paddocks with horses, ponies or donkeys (watch out for electric fences!) and turn left twice.

(13) At the end of these paddocks, turn right onto the wider path that leads to the plateau and its cultivated fields.

(14) At the Croix Saint-Jacques, at the entrance to the village of Davron, turn left onto Rue Saint-Jacques.

(15) At the end of this street (church), turn left onto Rue de Wideville, named after the estate you will pass later, and walk past the cemetery. Walk along the estate fence on your right until you reach a crossroads you took on the way there.

(3) Continue north-west and follow the same route as on the way there, crossing the stream again and returning to the church in Crêpières (S/E).

Notes

Picnics are possible near the entrance to the Paric de Grignon (AgroParisTech). At point (9), turn left and walk down to the entrance gate of AgroParisTech (with the small Grignon post office on your left). Just before this, on the left, there is a square with a bus shelter that is a convenient place to picnic.

In wet weather, the path between (12) and (13) is very muddy because animals use it daily.

 Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

Hike completed on a dry day in December during the week, alone in nature.
Very pleasant scenery all along the way, with pretty villages breaking up the monotony.
Crossing the fields was rather pleasant at this time of year, but I can understand that it might be more difficult in the height of summer.
In fact, when walking along the road (about 10 minutes), we preferred to stay on the right-hand side to feel safer, but it was nothing serious.
One last thing: the start of the route is within earshot of a gendarmerie training centre (you can't see it). If there's a training exercise, you can hear the sound of gunfire. No danger, of course!
All in all, we really enjoyed this outing. Thank you for this route.

Hello, Gérard
Yes, I understand, and I've actually tried to find an alternative route. I was wondering if, by going through the farm in Grignon and then back through the fields, we could come out onto the little lane that goes downhill... I'll try to check it out and let you know.
Thanks anyway for the hike

Hello,
I am the author of this hike.
Unfortunately, the section on the D119 is unavoidable on this route because the INRA and the former Agroparistech site prevent any detours.
This section is only 500 metres long, but you do need to be careful.

Hello
Route taken during hot weather
The section through the woods at the start was very pleasant
It's a shame you can't see Wideville Castle
Then a long, uninteresting route through fields
The village of Thiverval was very nice
Then a less interesting section of the Grignon golf course
Tarmac and the D30 road, which was very busy and even dangerous for pedestrians as there was no safe verge
Downhill section into the valley and a very nice mill
Monotonous fields and finally a visit to Davron, which was very nice
So, overall, a mixed bag
The main problem is the dangerous section of road. A detour route needs to be found...
Thanks

A very beautiful hike. The route is fairly easy to follow. I only had a slight doubt at stage 6, walking along the golf course, as I couldn't see the GR mark to follow, but you just have to keep going straight ahead.
I particularly loved the diversity of the landscapes, with a special mention for the wash house and church in Thiverval.
Also, don't hesitate to take a little detour at the beginning or end to visit the restored wash house in Crespières.
Thank you for this beautiful walk!

Message:

We did hike no. 203944, Crespières, etc., very good!
I suggest a change between markers 6 and 7: you rightly say that this section is "the most unpleasant part...", which is true, and we avoided it as follows:
At point "6", cross the roundabout and take the GR1, then turn left to go
la Pièce des Vignes, and from there reach point "7"
It's much quieter and less dangerous.

Best regards, Yves Lacroix

There are lots of mountain bikes in the morning, but the people are very friendly and let you pass with a smile, so what more could you ask for? The hike is easy with no notable difficulties, a little mud here and there but no hills!
The villages you pass through are beautiful, with beautifully restored houses. You feel a long way from Paris

taking the detour between points 6 and 7 along the GR trail beside the future golf course is very pleasant

The section along the D119 between 6 and 7 can be avoided by crossing the roundabout at point 6 and continuing on the GR1, which runs alongside a golf course under construction. At the end of the golf course, ignore the path that branches off to the right and continue straight ahead on the grassy path that leads to a tarmac road and a housing estate. Immediately after the houses, take the path at a 90° angle to the left, which leads back to point 7.

The first and third parts are fine, but the 1.5 km walk along the main road and the descent into the village of Grigon are very disappointing. This busy road is uninteresting and even dangerous. The only reason to take this route is to see the entrance to the agricultural college, which is just a few metres out of the way. I did this walk again, avoiding this part. It is much more interesting to cut across before the village and walk along the park on the north side. Obviously, it is several kilometres shorter, but it can serve as a warm-up for a pleasant afternoon. Too scary on the main road

The walk was very pleasant. Very varied. It's a shame about the section that runs alongside a main road.

Same comment as the others about the obligatory passage at the foot of the wall...
Otherwise, exploring the villages is very enjoyable.

Hello Yannolivier,

If you look at the previous posts, you will see a reply from a moderator who knows the area well.
They confirm that it is virtually impossible to avoid taking the D110 since the AgroParisTech park is closed to the public.
Nevertheless, any suggestions you may have for improvement are welcome.

Gérard, the author of this hike.
