Bréviande Forest and Menhir du Grand Berger

After reaching the Vives Eaux dam, return to the starting point, passing by the ruins of the fortified farm of Les Joies and discovering the Menhir du Grand Berger in the middle of the woods.

Description of the walk

Park in the parking spaces along Avenue de la Zibeline, in front of the tennis court.

(S/E) Cross at the pedestrian crossing and turn right towards the roundabout and the retirement home. Turn quickly left into Allée des Acacias and follow the red and whiteGR®2signs. After about 100 metres, take the path on the left into the undergrowth.
Follow the signs along the left side of the first four ponds.

(1) Behind a school complex, take the footbridge on the right, then turn left to go around the last pond. Cross Avenue de la Zibeline and take the small path directly opposite. Cross Rue de l'Aubépine, then turn opposite and slightly to the left into Square du Cerisier. At the end, turn right between two houses and enter the forest.
Follow this path, which winds its way through the forest, following the red and white markings. When you reach a large clearing with a roundabout, take the lane that branches off slightly to the right. Follow this lane until you reach the next five-way intersection.

(2) Follow the gravel road heading south-west. Pass two pumping stations and, at the junction with Route des Pommiers, continue straight ahead to the edge of the forest.

(3) Turn right onto the road (please note that theGR® has been modified and does not correspond to the map). Then, after about 200 metres, take a small path into the woods on the left. Leave the next two grassy lanes on the left and take the third (Rue Bas Boire), leaving the GR®.
At the end of the street, turn right onto Rue François Rolin and continue to the Saint-Germain d'Auxerre church.

(4) Cross at the pedestrian crossing, then turn right onto the road that goes downhill (Rue Pasteur). After a few dozen metres, turn left onto the lane along a fence, then at the end, turn right into a park.
Follow the path downhill towards the playground until it intersects with theGR® (view of the Seine and the Vives Eaux dam).
Turn left at the hairpin bend to go back up into the park, following the red and white markings. After about 150 metres, take the lane on the right and continue to the park exit. Turn left onto Chemin des Pavillons, then right onto Chemin des Boissettes.

(5) At the end, turn left onto Chemin aux Loups. At the roundabout, leave theGR® and cross at the pedestrian crossing to enter Rue aux Loups opposite. Follow this road, which soon becomes a stony path, and continue straight ahead, ignoring the paths on either side. Return to the tarmac at Rue des Joies and continue for about 50 metres.

(6) Take a small path on the right that runs alongside the old moat of the fortified farmhouse Les Joies, the ruins of which can be seen on the left. The path leads to a large lane; follow it to the right. Cross a road and continue straight ahead.

(7) After about 300 metres, take the path on the right, which soon turns left. Cross a large lane and continue straight ahead. At the next intersection, turn left. Ignore the paths that branch off to the right and continue until you reach a wide gravel forest road.

(8) Take it on the right. Continue straight ahead at the next junction, then turn left (elevation 73) and continue until you reach a group of houses after passing through a gate. At the junction, you will see the Gros Chêne farm on the right and a lane with a gate on the left. Head towards the latter.

(9) Take the path (not shown on the map) to the right of the gate. It turns left, then splits in two. Take the right-hand path. The Grand Berge menhir is a few dozen metres away.
Turn around and go back to the gate. Follow the road on the left that runs alongside a field until you reach a paved street (Allée du Hêtre).

(10) Turn right onto this street, which soon becomes a path. Cross a road where traffic can be heavy (Allée des Lilas), and follow it to the right on the left-hand side for about 180 m. Take the path on the left without entering the housing estate, and follow it to Avenue de la Zibeline. Turn right and return to the starting point in front of the tennis court (S/E).

A very pleasant parish-specific to Brittany walk with no elevation gain, beautiful forest and lovely quays along the Seine, though the second part is less interesting.

We followed the GPX route but encountered a problem with the trail at point 3. The rest of the hike went smoothly.
We did the hike in the sunshine at the end of March and enjoyed picking daffodils and stopping for lunch at a restaurant near the Saint Germain church in Auxerre, which I would recommend. I would suggest extending the hike near the Seine to make it a bit more interesting.

The start of this walk made me a little nervous... pavilions, paths that were very organised, like in the USA!
But then, once you enter the forest, it gets better. No difficulties, benches for picnics in a park before the lock. This easy walk is very pleasant; the menhir isn't particularly remarkable, but the very wild path leading to it allowed me and my dog to discover, quite unexpectedly, a family of wild boars...

A hike to stretch your legs before tackling steeper and less well-equipped trails. The dam on the Seine is worth a look. For the rest, it is always surprising to see how new towns have sought to build in the countryside, even in the forest, without hesitating to transform it. The young people of these areas would do better to walk rather than roam around on noisy motorbikes in a forest that has done them no harm.

A very pleasant walk, mainly through woodland. No difficulty, and not very busy for a Sunday.

A pleasant hike even in winter, with no difficult sections along the route.
The dam site is interesting and worth a visit, while the menhir is more of a curiosity than a point of interest.
For me, this was a reconnaissance trip to check out the route before taking a group there.
I'll be back in summer

We completed this varied route in a small group. The dam is magnificent. To get a good view of it, don't turn left at the signpost, but continue straight ahead along the Seine on the left to reach the dam.
At the end, we rejoined the trail.
The path to the menhir is fairly easy to find. There is now even a sign halfway up a tree and some trees have a large white mark.
To return, at the end of point 9, when you reach the first houses, go straight ahead along Allée des Glycines, which passes between houses with wooden fences.
Then, crossing a road at the pedestrian crossing, you arrive at the ponds in the park where you started and turn right to find Allée des Acacias further on.

Hello,
At the end of point 4 (view of the Seine and the flood barrier), we continued along the banks of the Seine on the left to climb up onto the footbridge over the barrier. We retraced our steps and headed straight for the pavilions. We did not go back up through the park.
It's a lovely spot for a coffee break or a picnic on the banks of the Seine.
The menhir isn't really worth a detour.

a pleasant family walk. However, the "menhir" is of no interest; it looks more like a rock left there by a prankster! What's more, the path to get there is almost invisible, hidden by brambles. The walk is not spoiled (although the title could be changed).

a gentle hike with little in the way of originality, but it allows you to stretch your legs in nature, which is already beneficial during this period of confinement

A wonderful hike for us, discovering the town of Cesson and its urban planning around a magnificent park
, then the forest and wide forest paths, and at the bottom, the Seine flow control dam with its double channel, which is worth seeing (by crossing the bridge structure on the site)
As for the menhir, it should be noted that the only difficulty is finding the start of the small path to the right of the barrier
but it's very easy to find if you're curious!
A hike to recommend.
