The Fosse Arthour tour

This easy hike allows you to discover the Fosse Arthour. It is a geological fault called a cluse, which gives the landscape an exceptional appeal.
This cluse forms a narrow, 70-metre-deep gorge carved into a rocky ridge and strewn with large boulders on its sides. The area is ideal for walking and climbing.

Description of the walk

Park in the car park just before the inn.

(S/E) Head towards the inn and cross the Sonce.

(1) Turn right immediately to take the path and leave the tarmac road. Continue along the path through the woods that runs along the cliff on the right.

(2) Go through the cattle gate at the edge of the woods, then cross the farm to reach the tarmac road. You will come to a Y-junction before the hamlet of Les Roberdières.

(3) Turn almost 180° to the left to climb the ridge. Reach theGR®22crossroads.

(4) Leave the road and take theGR® 22 on the left at the top of the ridge. Continue along this path to the calvary, taking the left-hand path at each intersection. Reach the viewpoint to enjoy the view from the top of the cliff.

(5) Continue down between the two rocky outcrops to reach the tarmac road.

(6) Turn right to cross the bridge on the left and reach the pond. Walk along the pond and continue straight ahead until you reach a car park.

(7) Continue along the road for a few dozen metres and take theGR® 22 path on the right. Follow this path until the next intersection.

(8) Leave theGR® here and take the path on the left that turns back into the undergrowth. Continue and cross the road to take the path that goes around the top of the quarry

(9) At the intersection of the four paths, take the path straight ahead that leads into the forest (the least obvious of the paths). Follow this path and return to the pond at the initial crossroads.

(6) Turn right after crossing the bridge.

(1) Then return along the same route you took to the car park in front of the inn (S/E).

The last part of the walk in the woods above the pond was not very easy because the path, which was clearly not used very often, was no longer very well marked. Fortunately, there was the Visorando trail

A very beautiful walk (partly in the rain – Storm Benjamin).
Crossing woods, pastures, little tarmac... with an inn at the start/finish point.

Very good parish-specific to Brittany hike, but be careful as the descent after the viewpoint is dangerous and very slippery in wet weather.

An excellent option for a short hike. Good footwear is necessary for the climb, but the rest of the hike is very accessible. A beautiful discovery of a lovely pond. I recommend it

A magnificent route that takes you along roads and through forests. Studded boots are recommended as some sections are tricky. Not suitable for beginners. At the top of the hill, take a short break by the pond, a great spot for photography and relaxation. The vegetation and rocks form a mountain landscape that is very pleasant to contemplate. The last forest section of the route is more like a single track than a real path. It is impossible to tire of the waterfalls, a well-deserved reward at the halfway point and end of the hike. When passing through these places, it is difficult to believe that their history is only the stuff of legend...

There could have been a variation to extend it because it is relatively short

A very pleasant walk in the right direction (meadows in the morning and woods in the afternoon, which is a good thing when it's very hot, as it was today). Varied views and terrain. I really enjoyed it.

However, there was a slight hiccup at an intersection between points 9 and 6. Should we follow the path we had been taking up to that point? That would be more logical. Or the tiny trail that seemed to lead into the woods? A trail where we had to fight our way through ferns taller than ourselves. I opted for the "fern fight" route because it followed the trail. But I doubt that everyone would like it. I liked it.

Picnic facilities available. The inn was open.

A very beautiful hike to do again this summer when the vegetation will be denser and the light will be completely different, but this region is magnificent and definitely worth discovering

Hello,

We came from Chartres to do this hike on a Saturday morning at the end of winter when the weather was nice. We saw hardly anyone and had lunch in the sun on the bench at the viewpoint. The fault is superb in every way, especially the granite escarpments and the banks of the small river. The nicest part of the circular route is the eastern section, with the passage in front of the farm at the bottom of the hill and the granite chaos. The western part through the woods and the old quarry is less interesting but makes for a nice walk in the forest. If you only want to do half the hike (about 5 km / 1.5 hours), choose the eastern part, starting to the right through the trees, just after crossing the river.

All in all, a very nice day out.
