Description of the walk

The car park is located next to the Agudelle cemetery.

(S/E) Leave the car park by taking the road from Agudelle to Saint-Simon-de-Bordes, which passes in front of the cemetery and the church gate. This section of the route forms part of the SaintongeGRP®® trail, marked in red and yellow.
After the last houses in Agudelle, the road bends to the right. Take the second road on the left towards Chez Gillet.

(1) In front of Chez Gillet, at the crossroads, take the farm track following the hedge of the beautiful property on the left.
The farm track leads towards the woods. The track gives way to a lovely forest lane.
Further on, the forest lane turns into a farm track at the edge of the woods (on the left). On leaving the woods, the track runs alongside a vineyard plot on the left.

(2) Almost immediately, turn left onto a wide farm track between two vineyard plots.
The farm track turns into a forest lane at the entrance to the woods.
Five to six hundred metres further on, at a crossroads, take the small path on the right which remains flat. This path runs alongside cultivated fields and continues through the woods, close to the edge.
After another left-hand bend, it soon joins the D151 road. Turn left onto the road leading down towards the Etang d’Allas.

(3) Before the lake and in the wide bend to the right, you will see the Petit Bois fish farm on the right-hand side of the road. Take the forest track that starts on the left and remains flat.
The path soon begins to climb. Continue, taking care to turn right to climb up to a plateau. The path runs alongside the Etang d'Allas deep within the woods, then, further on, takes a wide bend to the left and begins to climb slightly again.

(4) Take the first path on the right, which once again runs alongside the shore of the Étang d'Allas deep within the woods.
The path turns into a farm track as you return to cultivated fields.
After a path that descends to the right towards the lake, there is a lovely view of it and the opposite bank. Continue on towards Chez Curoux.
Turn right onto the road which descends slightly to go round the houses in this hamlet.
The road heads towards the hamlet of Le Groisard, which you leave on your left, then passes further on by Le Grand Maine (on your right) before coming to an X-shaped crossroads.

(5) Cross the junction carefully and take the road opposite, which runs alongside the houses at Chez Houmeau.
Continue straight on, including taking the farm track on the right at the first houses in Agudelle.
At the crossroads, turn right onto the road leading to the 19th-century château known as Maison de la Tour.
The farm track runs between the farm buildings adjacent to the château.

Note: during wet weather, the track can be very muddy due to the farm’s tractors.
Continue straight ahead along the track, which crosses a small stream before climbing slightly towards a wood, in front of which it turns sharply left.
Further on, the farm track takes a wide bend to the right as it enters the woodland. Ignore the track branching off to the left.
When you reach the clearing, walk along the right-hand side of the recently installed fence at the edge of the woodland. Continue along a narrow path between two embankments in the forest for about 150 metres (the path is poorly marked and not always clearly visible for about 30 metres).

(6) The path leads onto a forest track, which you take by turning left.
The forest track runs along the edge of the woodland at times and through sections of woodland at others. Continue straight on until you reach the D154E1 road.
Cross this small road with care and continue along the forest track opposite, between the vineyards.
Continue straight on until you reach a T-junction. Turn right, with your back to the hamlet of Chez Mathieu.
Shortly afterwards, at the corner of a vineyard plot, turn left onto the farm track leading towards a Y-junction of small roads.

(7) Turn left onto the road leading towards the hamlet of Chez Mathieu, which you leave on your left.
At the next crossroads, turn left towards the woods. The road curves to the right and follows the edge of the woods.
Continue to the next crossroads, where the route takes the left-hand road back to Agudelle.
At the entrance to the village, walk past the cemetery and the church before reaching the car park on the left, which marks the end of this walk (S/E).

Notes

This hike across varied terrain requires sturdy footwear.

This route is unmarked, although certain sections are signposted, such as theGRP®® de Saintonge (Red and Yellow) or the GP31a (Yellow). It is therefore advisable to follow the directions in the description and on the map, combined with a good understanding of the landscape, as this walk does not present any major difficulties.

Worth a visit

Agudelle
In the 12th century, the forest of Agudelle belonged to the Order of Fontevraud. The chapel was donated in 1116 to Lambert, founder of the Abbey of Notre-Dame de La Couronne, to establish a priory there.
The Church of Saint Eutrope, the construction of which began in the 12th century, has been listed as a historic monument since 31 December 1986. A polychrome wooden statue of Saint Eutrope dating from the 17th or 18th century has been listed since 21 January 1980. It was restored in 1988 by Christian Karoutzos. The church houses a bronze bell dating from 1556, which has been listed as a historic monument since 5 December 1908.
The Maison de la Tour, dating from the 19th century.

Saint Simon de Bordes
During the Revolution, the commune was known as Simon-de-Bordes.
The bell tower of Saint-Simon-de-Bordes was destroyed during the Second World War and replaced by another. Because the bell tower of Villexavier had also been lost, the two bells were subsequently accidentally swapped: looking closely at the one from Saint-Simon, one can see ‘Villexavier’ engraved on it, along with a date.
Saint-Simon Castle
The Château de Saint-Simon de Bordes was built by Marie-Charles du Chilleau, Lord of Airvault, Sainte-Lheurine, Moings, Villexaxier and Saint-Simon, and Governor of Saint-Domingue. This château was sold during the Revolution as national property. After being set on fire during the night of 28–29 September 1889, certain alterations were made, notably the addition of 19th-century-style windows.
Saint-Simon-de-Bordes Church
The church, a 12th-century building, was listed as a Historic Monument by decree on 5 December 2000. The two arms of the transept were rebuilt in the 19th century.
Les Six Épis
Les Six Épis is a residence that belonged to Fernand Larquier, Doctor of Law, lawyer, former magistrate, mayor of Saint-Simon-de-Bordes and Member of Parliament for Charente-Maritime from 1902 to 1914, a great defender of the local distillers.

A short route, interesting because it is easy. A little too much tarmac, but you also pass through pretty woods, which is very pleasant in autumn when the weather is good. I recommend it for those who don't want to do a long hike but want to get some fresh air for 1½ to 2 hours.

Hello, this route is no longer very well maintained and the signposting is ageing and rather basic. Furthermore, it has been altered as local residents have fenced off and privatised certain sections of the route. The circular route from markers 1 to 5 is very pleasant on the way back to the village of Agudelle, but the circular route from markers 6 to 7 is a real headache. Two U-turns due to barriers and fences. Return via the road. It’s a shame.

Hello,
Thank you for your message.
However, it requires some clarification. In the description, I stated that the route is “unmarked, although certain sections are signposted, such as the GRP® de Saintonge (red and yellow) or the GP31a (yellow)”. This explains why walkers may come across crosses at the entrance to certain sections... as the route does not follow marked routes but may cross or use sections of existing marked routes.
As for the path being blocked by a string after the Ferme de la Tour, this is a practice used by a farmer who takes his animals out to pasture and brings them back in the evening (for milking or to put them to sleep in the barn). For convenience, in isolated areas that he alone manages, he sometimes leaves the string in place. This should not prevent the hiker from passing through, provided they respect the string (which must be left in place, just as when one sometimes passes through a mountain pasture entrance and must close the gate behind them).
As for the last comment, if I’ve understood correctly (I would have liked more detail with the help of the map), the path between the vineyards joins the GR which (with some exceptions) cannot be blocked by herders or farmers.
I’m not from the area but hope to return soon. If I do, I’ll try to go there to get a better understanding.
Happy hiking.

Hello,
The route from the Ferme de la Tour does not follow the terrain; the path leading out of the farm is blocked by a rope, and if you continue, you come to a cow pasture and the path ends; Furthermore, after the road, the path through the vineyards is a dead end and also leads to a cow paddock; on the ground, there are crosses at the entrance to the Chemin de la Tour, which contradicts the description and map on the website?? If the route is changed, this walk needs to be updated

The route of the GRP on the map is somewhat arbitrary: it actually continues straight on after point 2; however, the path branching off to the left is clearly visible.

A minor issue involving farmers who take it upon themselves to block off and close off paths.
In fact, during this walk, between points 5 and 6, shortly after the château (mansion) de la Tour, a farmer has fenced off a meadow with barbed wire, enclosing the path and thus blocking it.
We solved the problem by going through an adjacent ditch, which is not maintained and is likely to flood during heavy rain.
Kind regards.

Hello
I’m sorry to hear about the barbed wire incident. Personally, I’m inclined to believe the first theory: for the sake of convenience, some farmers block off paths without bothering to provide a way for walkers to get through. It’s quite rare for them to actually own the paths… even though some local councils have ‘sold’ them off recently.
Best regards.

Hello,
We went on this hike yesterday. It was pure bliss – very few roads, magnificent views, particularly by the lake where we had a picnic.
The only downside for me was that there were no signposts for a good part of the route, especially towards the end of the walk. As I hadn’t printed out the route description, I spent too much time, for my liking, with my mobile in hand reading the directions.
However, be careful when you reach the edge of the clearing at the end of the walk: the path was blocked by barbed wire. We had to climb over it to continue... either the farmers have moved the gates to let the cows pass between two fields, or they no longer tolerate walkers passing through their land...

No problem, it’s not your fault. And the unexpected turn of events wasn’t too bad!! The route we took is very quiet!!
It’s a recurring issue for those who, like you, blaze the trail. Finding a route that’s passable at one point but then becomes impassable later on.
And it’s only natural for those following your route to bring this sort of issue to the attention of future hikers. Perhaps in winter the path remains passable (though difficult given the current state of the vegetation).

As the farmer owns his land, it is difficult to ask him to do any more than give the area along the fence a quick clean with a pressure washer… over a width of one metre, but the vegetation quickly takes over again.

Best regards and thank you again.

Hello,

I’m sorry to hear about this unexpected problem. Some farmers are quicker to include paths within their fenced-off plots than to help maintain a proper route.
Personally, I was able to reach the lovely farm track nearby by walking between two embankments for about 150 metres. At the time, there were no brambles.
You were right to turn back and take the path previously left on the left in order to get back to the road and thus rejoin the rest of the route. My initial choice was simply to minimise the distance travelled on the road.
I fear that this is now the only viable option.

Enjoy your walk

Hello
A lovely, varied walk, alternating between shade and sunshine. I think the fish farm mentioned has closed down. The ponds are completely dry and overgrown with grass.
No issues with 90% of the route…
BUT BEWARE
"When you reach the clearing, keep to the right and follow the recently installed fence along the edge of the woods. Continue along a narrow path between two embankments in the forest for about 150 metres (the path is poorly marked and not always clearly visible for about 30 metres)."
Here, as this circular loop is rarely used, if ever! the "path" (or passage, if there is one) is IMPASSABLE by late summer, overgrown with brambles and thick undergrowth. You’ll need to be kitted out in trousers, a long-sleeved jacket and a pruning knife to even consider walking along the fence. We turned back and took the D154 to rejoin the route where it crosses this road.

Thank you for this route.
