The Grand Suzon valley

An easy walk, despite the distance. You will walk either through the heart of the plateau's crops or through woods. To finish, you will descend the very pretty Grand Suzon valley. The stream is often dry, but... not always!
If the weather is clear, you can enjoy some beautiful views of the surrounding peaks.

Description of the walk

(S/E) In Saint-Barthélemy, with the church behind you, take the departmental road on the right (west, towards Beaurepaire).
After the café, take the first lane on the right, which quickly turns into a gravel path.

You will come out onto a small asphalt road (signposted "Boussard"). Continue straight ahead, as if you were continuing on your way. You will pass a first path on the right that leads to a farm.

(1) Take the next path on the right (a yellow sign will guide you). Follow it until you reach a T-junction. Turn left.

When you reach another T-junction, turn right until you reach the next junction.

(2) A faded sign indicates that you are in the Plaine d'Arcieu. Turn left and then quickly turn right onto a grassy path towards Les Revollet (new Plaine d'Arcieu sign).

(3) When you see a pond on your left, you will come to a small tarmac road which you take to the left. Be careful, a little further on, at the end of the meadow, you will take a path on the right at a 45° angle (follow the yellow markings). It is a little hidden.
When you reach a sort of pass, turn left and go up into the woods.

(4) In the woods, you will come to a fork (signposted "Les Revollet"). Take the right-hand branch towards "Le Diaret". You will come out into a field. Ignore the path that joins yours at a 45° angle on the right.
Be careful, when your path reaches the edge of the woods, you must descend to the right. Here too, the path is somewhat hidden.

(5) At the bottom of your path, you will come out onto a road. Make a left/right zigzag. You will very quickly reach a second road where you make another left/right zigzag (if you have had a picnic, take advantage of the recycling bins to lighten your load...). You are now on the Chemin de la Planche, walking alongside the sewage treatment plant's plantations.

(6) You descend to a ford. A sign warns you of the danger this ford may pose in the event of flooding and urges you to turn back in such cases.
If there is no flooding, continue to the bottom of the valley. Your path turns left, then right (in autumn, it is somewhat hidden by leaves). Cross a second ford and climb back up onto the plateau, which you will cross.

(7) In the middle of the plateau, you will see a sign for "Le Diaret". Continue straight ahead until you reach a complex crossroads with a picnic table, strangely placed in the middle of nowhere...

(8) This crossroads is marked by a sign for "Plaine de Braye". Take the first dirt track on your right, which starts at the corner of the small wood. Go down the valley, ignoring anything that may come from the right or left.

(9) You will pass a third ford, also marked as dangerous in case of flooding. Your path makes a chicane to the right, then to the left, to change banks with respect to the stream.
Continue downhill for quite a long way until your path becomes tarmac. Continue downhill, going straight ahead.

(10) You will come out onto the D519 and turn right. This section is safe thanks to the pavement. It is not particularly interesting, but... you have to get back somehow... Continue to the church, where your vehicle will be waiting for you (S/E).

Notes

Please note! This walk crosses three fords. Although the stream is usually dry, it is not advisable to undertake this walk if there has been heavy rain or if heavy rain is forecast.

The walk starts in front of the church in Saint-Barthélémy, a small village on the outskirts of Beaurepaire, to the east.

Beaurepaire has all the shops and services you may need.

Part of the route is marked in yellow, but not systematically. The commentary refers to the markings when useful.

Worth a visit

In Hauterives, south of Beaurepaire, you can visit the Ideal Palace of Postman Cheval.

In windy weather and at 3°C, we pushed on to the Notre Dame de Tournin chapel and then Pommier to fill the day.
Beautiful panoramic views all around.
We didn't meet anyone else, but it was certainly cold!
Thanks to the author.

The only slight downside in the first few kilometres, just before the farm in the valley, is that the route takes you along a path at the edge of the forest and alongside a field, but this path is not maintained.
Very tall grass, brambles and nettles...
Apart from this section, the rest is very accessible and the atmosphere is very bucolic...
I recommend it for an easy, pastoral walk.

A pleasant little walk to get some fresh air and explore the surrounding area
Stream and paths are dry, but grass is tall in June, so wear trousers

Thanks to you, I finally found a way to connect St Barth to Pajay via hiking trails.
We started the hike from Beaurepaire, then at one point we turned off towards Pajay and finally we extended the hike along paths we knew.
Thank you for this discovery.

The hike would obviously be better when the vegetation is more lush than it is at the end of December! On the other hand, I didn't see a soul, so it was completely peaceful from start to finish...
The path to the water treatment plant was barely passable that day because it was so muddy. Overall, it was an easy and very pleasant hike, especially in the numerous woodlands.

Note: instead of returning to the centre of St Barth via the main road, I took first turn left then right after crossing it and followed a much quieter little road along a stream, keeping to the right until I reached the church (about 1 km further). Total duration: 2 hours 45 minutes.

Perfect explanations for following the route.
Slight difference in elevation: I found 114 m instead of 96 m.
A very pleasant hike.

A breath of fresh air through woods and plateaus, a touch of colour along the edge of the path in the woods, provided by the bright red berries of the holly.
Forestry work between the Revollet sign and the first ford, path passable but muddy.
A hike to be done on a fine day, to discover the beautiful vegetation that can be glimpsed on the edge of the Grand Suzon.
Thank you to the author for the perfect description.
Best regards. Ly.
