Description of the walk

Climb above Saint-Symphorien-de-Mahun, pass the hamlets of Gonnet and Gaspard, and continue on a road that is unpaved for a certain distance. Once back on the paved road, continue to a fork. The hamlet of Les Soies is below.
Park your vehicle near the hamlet of Les Soies.

(S/E) Take the forest road on the left. Continue along this road, passing the hairpin bend on your right, to reach the Croix de Boiray at the crossroads of five roads and paths

(1). Turn left towards Scree Blanc, via the Annonay basin tour alternative route. The road turns twice at 90°. After the second turn, you will come to a crossroads.

(2) Leave the road and take the stony path that climbs through the undergrowth. You will reach the Col de la Supyère.

(3) Take the road on the right to go around Knoll des Chomeilles and then reach the Croix du Knoll crossroads.

(4) Turn left and follow the signs for Scree Blanc, taking the very stony path that climbs quite steeply. You will then return to the eastern slope. The climb is made more difficult by the fact that the path is very loose with large stones due to the motorised vehicles that use it and erode the ground. At the top of this path, you will arrive at Croix du Barry, which is also the other name for Scree Blanc. Opposite this cross is the path that climbs up to the oppidum. It will only take you a few minutes to visit it. Return to the path you left and descend to Croix de Signolle.

(5). Here, there are four possible directions. Continue straight ahead until you reach another crossroads with six paths, the Croix des Tramezières.

(6). Take thesecond path on the left.
Walk along the knoll of the Aulanières, ignoring two paths on the left, and after passing La Paute, cross another junction.

(7). Continue along the same path to follow the knoll of Beauplot, keeping to the same mountain side. You will then reach a clearing, which is a good place to take a pleasant break before continuing the climb along the Scree Long, where you can admire your first panoramic view of the Pays d'Ay. Turn around to see the landscape towards the knoll of Vent. Pass a fork in the path.

(8) Turn left and you will reach the Rocheplate spring, which is not developed but is tapped and refreshing. Continue climbing towards Clos du Rouvey on the wide, gently sloping path. Before reaching Clos de Rouvey, the forest road turns right to join the D532.

(9). Continue along the path on the left. Enter the undergrowth. Pass Clos de Rouvey and, after climbing Bresseau, begin a fairly steep descent along the rain-eroded path to join the D532.

(10) Take it to the left and follow the meadow until you reach theGR®430, which crosses the road.

(11) Take it on the left, entering the forest on your left towards Mont Chaix. You will climb and then descend to reach a crossroads of forest roads.
At the crossroads, take the path straight ahead. You will then wind your way through a very pleasant, cool and airy forest until you reach a clearing at a place called Mont Chaix.

(12) Turn right towards Lalouvesc, continuing on theGR®430to see the mushroom information route on the left.

(13) Return to the clearing.

(12) Continue straight ahead on the path towards Knoll de Boidel.
Note: there are two paths here:
- one is very pleasant, wide and grassy, branching off slightly to the right. Unfortunately, do not take this path as it is a dead end, blocked by a landslide.
- the other to its left, which descends into the forest. This is the one you should take. Descend a little, then climb back up to join theGR®420.

(14) Turn left to descend to Knoll de Boidel, then to Knoll de Frachy, and you will arrive at a forest road with a fenced field on your right. Take this road to the right until you reach a cross at a new intersection.

(15). Continue straight ahead, leaving the path that descends to Four des Tuiles on your right. Follow the knoll of the Blache until the road turns sharply to the left.

(16) Turn right onto the path towards Veyrines. Be careful not to miss it. Pass the knoll du Trou and descend to Veyrines. Here you can visit the church.

(17) Pass in front of the church and take the road on the right that runs alongside its lawn. Then turn left and continue along a narrow path until you reach the road at the hamlet of Hermuzière.

(18) Go up the road on the left until you reach a junction leading to Grand Soulage. Cross the road and follow it to the left as it curves. Keep to the right-hand side of the road because, before the next bend, you need to turn off onto a forest road on the right. Follow this quiet, rarely used road gently uphill until you reach a crossroads just before the buildings at Boirayon.

(19) Take the grassy path on the left. Be careful here as this path is cluttered with fallen trees, but some have been cut away. Cross a stream after a descent through the undergrowth, then start climbing the ridge to reach the hamlet of Gonnet.

(20) Turn right onto the tarmac road, pass the hamlets of Bellevue and Gaspard, then turn almost due north. You will then come out at the hamlet of Les Soies and find the car park (S/E).

I preferred to start from Verynes, as this avoids ending with a climb
There is only one difficulty, apart from the distance. The paths are often wide and passable, even tarmaced. There is a lot of shade, so there are few panoramic views. I therefore consider it more of a walk than a hike.
Have a good day.

It would be wise to start the hike from a wayside cross located after the place called "the peatland". There is a sign at this location indicating "Les Soies".

Parking is available at this location.

This allows you to warm up before starting the climbs.

The hike is very pleasant. Plan to stop for a while in Veyrines to visit the church and climb the bell tower.

A hike without too much difficulty. The app was very useful at times because we were a little unsure when we came to several forest paths.
At point 10, there are wind turbines on the left before the D532. I think they are fairly recent because we couldn't find the path indicated in the description.The app told us to turn left onto a small tarmac road with a wooden barrier (no vehicles except service vehicles, I think). We went through the barrier and followed this small road. We passed very close to the five wind turbines and found the trail at the end of this road, which ends with another wooden barrier...
This hike is also very good in hot weather as there is quite a lot of pleasant undergrowth.
Thank you to the author for this beautiful route.

The hike is very pleasant and well shaded, which is very important in hot weather.
Having the map as a supplement means you can't go wrong.
The detour to Scree Blanc (oppidum) is a big plus with a superb panorama.
A little tip and a small comment:
- starting at point 20 or 22 allows you to avoid the climb at the end of the hike
- at point 5, Knoll, take the path just to the right of the cross

Taken just after point 12 (road bend, parking available).
Lack of description between point 24 and point 1 from the end of the road (pass and cross).
Lovely route. The Veyrines chapel is superb.
Thank you for this itinerary.

Departure at 8:45 a.m. and return at 5:30 p.m., but we skipped the circular at point 13. Nice weather, a little cloudy in the afternoon.
We chose to start the walk at point 22, where there is a platform for parking cars. This avoids having to climb back up to Les Soies at the end of the walk (a 260-metre climb).
A small detail at point 23: before Boirayon at altitude 721, you need to turn left; a sign indicates the Renardière car park.
The detour to Scree Blanc is well worth it: it is one of the most beautiful viewpoints on the hike and also an ideal picnic spot (for those starting from the same point 22 as us).
When you arrive at Clos du Rouvey between points 10 and 11, you will now find a field of wind turbines. The easiest route is to take the small gravel road that follows the wind turbines, which will bring you back to the trail.
A stop at the Romanesque church of Veyrine allows you to admire the beautiful roof structure, which has just been renovated. For the more adventurous, it is possible to climb up to the bell tower via a tiny staircase.

We were a bit disappointed with the scree Blanc section, as it was mostly wooded.

A very beautiful hike, your route and your comments are great. It took us 7 hours because we got a bit lost, but don't worry, it was our fault!!!

A beautiful hike, challenging due to its length, in a very wild region. The oppidum of Scree Blanc is worth visiting.
We missed the path at Boirayon, but found our way back onto the trail via the small road at the exit of the hamlet.

Yes, of course, but what will you do when the markings disappear?
With Visorando, the description should be enough; the map is just a bonus. Local markings are a plus when they're done well.
