Description of the walk

(S/E) Departure from the church in Berchères la Maingot.
When facing the church, turn right and then left onto Rue Fernand Hereau (towards Bouglainval).
After 150 metres, turn right onto a path. Continue until you reach Rue du Couvent, then turn left onto the D327.4 and leave the village.

(1) After 100 metres, take the path on the right (Sente du Chapitre) for about 2 kilometres, crossing two small roads on the left of the village of Théléville.

(2) At the entrance to the woods, take the path on the right at the fork.

(3) Pass in front of the cave (remains of an aqueduct gallery). At the next fork, continue right for about 2.2 km, crossing the D136.

(4) Turn left onto the third path after crossing the road. Continue straight ahead until you reach the entrance to Bouglainval on the D106.4 and turn left.
In Bouglainval, turn right onto the D26.1, then left onto the road that runs alongside the castle grounds.
When you reach the road, turn left and follow the castle walls.

(5) At the water tower, turn right. After 100 metres, turn left then right to reach the church.

(6) Turn right onto the road and turn left after the cemetery, cross the bridge, turn right and take the uphill path. Continue along the path to the left after the pylon and continue for 1.7 km.

(7) Cross the Vallée des Larris stream and continue straight ahead at the fork in the road.
At the edge of the woods, turn right onto the path. The first sign provides some information about the history of this part of the canal. Continue along the path until you reach the second sign.

(8). A wooden platform allows you to admire the masonry structure known as "la Grande Arche" (the Great Arch).
Turn around. Back at the first sign, take the small path on the left that goes up into the woods.

(9) When you reach the cave, turn left and then shortly afterwards turn right. Continue along the path that runs alongside the earth embankment and then passes between the two ponds.

(10) At the edge of the woods, turn right, then left when you reach the small tarmac road.

After 400 metres, take the path on the left which will take you back to the rear of Berchères church. Turn right onto the road to return to your starting point (S/E).

Hello,
The first two-thirds of the route are uninteresting, as you walk through fields of wheat and rapeseed in grass that is very tall at this time of year. There are no cultural attractions.
The last third is a little better, with the remains of a cave in the aqueduct and a more pleasant path through a small wood.
Not recommended for children!

An easy and very pleasant route, but be aware that it is not signposted at all, although the information provided is accurate. Unfortunately, the huge ruins are completely hidden by vegetation, but this gives it a sense of exploration ;-)

Beautiful walk in the countryside with a few cultural stops. Thank you, Louis XIV.
Disappointing Blainvillier Castle, where you can only see the roofs. A shame and frustrating.

Hello
I tried to get from Berchères to St Piat, following some of the routes.
I had to turn back at the large archway.
Best regards

Beautiful walk, but be careful, there are no markers, so you need to know how to interpret the description and the map. At point 2, we didn't see the cave; it may be hidden in the undergrowth.

An easy and very pleasant hike/walk, well documented in the time indicated without any strain... The path is sometimes narrow in the undergrowth, which adds spice to this adventure!

Zen in the countryside: deer, hares, rabbits and pheasants can be spotted along the way!

You'll discover the Grande Arche in the middle of nowhere, built by our ancestors just to entertain the King. It was a colossal undertaking for the time, led by Vauban: to bring water to supply the fountains of Versailles... breathtaking, go and see it!!!

Don't forget to visit the Maintenon aqueduct, located a few kilometres away, which is part of this irrigation system!

A very good description that we were able to follow without difficulty.
One minor issue regarding point (9): passage between the two pools => It would be useful to specify that these are large permanent pools, as we hesitated and tried to pass between residual pools that were not the ones indicated.
Fortunately, once we reached the other side, we immediately realised our mistake.
However, we saw several paths leading off to the left that were clearly paths between two low-lying areas of land, but without any pools.

As for the appeal of the route: living in the area, I had no illusions; good hikes are hard to find.

Hello
I wanted to give my opinion on the hike we did on 1 December 2016 on the Port de la Gravette route.
At number 9, we were forced to go the wrong way, so we turned right, then left to take Rue des Mésanges.
Apart from this minor issue, we had a good hike.
Thank you
Laurence and Pierre
