From Moussy to Saint-Martin d'Ablois, Brugny Vaudancourt and Chavot

This short hike through vineyards and woods takes us to the Cubry Valley and along the route of the old CBR (Reims Suburban Railway). It offers a glimpse of a little-known curiosity: the Pierre Saint-Mamert, where a hermit once lived. This stone is on private land where walking is tolerated provided that visitors respect the site.

Note: the spelling on the IGN map is incorrect; it is indeed the Pierre Saint-Mamert.

Description of the walk

(S/E) From the car park, take Rue de la République on the left, then turn left at the war memorial. Take Rue Prélot on the right, pass in front of the town hall and go straight up through the vineyards.

(1) At the crossroads, continue straight ahead towards the vineyard lodge. When you reach the edge of the woods, turn left and walk to the vineyard lodge.

(2) At the crossroads, turn left. The path zigzags through the vineyards without really changing direction. It joins the woods (yellow markings). Continue along the edge of the woods.

(3) When you reach a real crossroads, take the recently renovated (and very uneven) path on the right that enters the woods. When you reach the edge of the plateau, turn left and follow the red hand-made signs that lead to Pierre Saint-Mamert. Without the app, it will be difficult to find it here.

(4) At Pierre Saint-Mamert, take a break and return to the previous fork.

(3) Continue to the right, along the edge of the woods. After a while, the path turns left and away from the woods towards the village of Saint-Martin. Walk to the first houses.

(5) Take the first proper path on the right, after the first lamppost. You are now on the CBR trail. Continue in the same direction until you reach the Mont Bayen road.

(6) Cross the D22 and continue straight ahead. Continue on the CBR, which is circular in the forest.

(7) Cross the D36 and continue straight ahead. Walk through the woods to the housing estate.

(8) Before the first house in the housing estate, turn left, passing in front of a rock. Take the grassy path that descends along the housing estate. This path then runs alongside the wall of Parc du Sourdon. Walk to the road.

(9) You can stop at Parc du Sourdon, the entrance to which is 100 metres on the right.
Turn left and take the road (Avenue de Paris) that descends towards the village. Pass the football field, then the wash house, and walk to the town hall square.

(10) Cross over and take Rue Tour Nicole opposite, which climbs between the houses and then the gardens. Walk to the Vertus road (D36), cross over and continue along the path opposite. When you reach a wider path, turn left.

(11) At the crossroads in the vineyards, turn right (PR® signposted). Walk to Brugny.

(12) At the wash house, turn opposite, pass in front of the castle entrance, then walk 300 m and turn left onto the small path (white marker).

(13) Continue to the left, passing in front of the abandoned farm and the equestrian facilities. When you reach the D951, continue to the pedestrian crossing and cross.

(14) Take the first right and enter Vaudancourt. Continue straight ahead, passing the wash house and fountain. Continue in the same direction along the path that runs alongside the vineyards. Stay in this direction and walk along the path through the vineyards to Chavot Church.

(15) Turn left onto the road that descends towards Moussy.

(16) Carefully cross the dual carriageway (D951). Continue straight ahead. Walk to the car park (S/E).

What was once a path now has a cadastral number, so it is private property. The farmer was therefore entitled to plough it.

I will change the route.

Hello, the 4x4 was already parked across the path in front of the woodpiles. We drove past, waiting to see if anyone would say anything to us.
What's more, a few metres to the right before the path, there is a post with PR signs.
Have a good day.

However, we encountered a problem after point 8. The path that runs alongside a large old property and a house was blocked by three enormous piles of chopped firewood. We had to do a bit of "climbing", and then the trail was completely off the GPX route.

I went back there today. It is indeed no longer possible to pass. In addition to the large piles of wood, there was a pickup truck completely blocking the path.

I will have to modify the route after checking that ploughing the path is legal.

Yes, yes
When you arrive after crossing the road, the entrance to the park is blocked, so you walk along the perimeter wall. There is even a large tree that has fallen in the field, which the farmer has walked around.
The outline of the Breuil castle estate, which looks a bit like an L on Google Maps, is no longer visible; the entire field has been ploughed.

Hello,

The wall you followed is the surrounding wall of an old castle, which is now a retirement home. I will go and take a look sometime.

Did you see the Saint Mamert stone?

Hello, we did the route today. A very beautiful route through vineyards, woods and fields, very pleasant.
However, we had a problem after point 8. The path that runs alongside a large old property and a house was blocked by three enormous piles of chopped firewood. We had to do a bit of "climbing", then the trail was completely off the GPX route. We then decided to walk along the boundary wall of the property to the left of the field to catch up with the path just before the other fields after a small wood. Perhaps the farmer ploughed everything, including the path, but we don't know if there was a path there. However, this is just an anecdote, but we did wonder about it, so for those who take the path, do as we did A nice steep climb, but not too long, just before reaching the church in Chavot.

Thank you. Fortunately, there is Sourdon Park, which offers shade and coolness, and is currently hosting a Vign'art exhibition.

A wonderful place to take a break or have a picnic.
