Description of the walk

Reach the Chapelle Saint-Pierre by taking the small road on the left at the entrance to Peyrus (signposted "chapelle"). Park in the car park in front of the chapel cemetery.

No signposts
(S/E) With your back to the cemetery, join the road and follow it to the right. At the first crossroads, continue straight ahead, cross a stream and continue slightly uphill to the Col de Toutes Aures crossroads.

Sparse yellow markings
(1) Turn right onto the path towards Toutes Aures. The gradual climb passes a water tank, then the path narrows and becomes shady. Ignore a path on the left. Shortly after, the slope becomes steeper, then levels out to reach a more open area at the Gros Pin signpost.

(2) Continue on the same path towards Planayses, leaving the path on the left 100 m further on. The markings are a little more visible from here. Continue in the same direction, leaving the next path on the left (private property) and continue to a small triangular esplanade. Take the road downhill on the right and continue for 150 m to the Planayse crossroads. Continue downhill on the right towards Le Forage (car park). Pass a renovated house and you will come to a tarmac road at the signpost for Le Forage.

(3) Follow this road to the right towards Les Condamines (car park). Shortly afterwards, ignore the Chemin des Peintres on the right and the path downhill on the left. Continue up the road and after house no. 2550, the path becomes stony and leads to the car park (signpost for Les Condamines).
Continue straight ahead on the path towards Mât Pierre. NB: for about 200 m, the path follows red and yellow markings. Go around a bend and you will arrive at the Mât Pierre crossroads.

(4) Turn right towards Pas de Saint-Vincent. Start climbing and quickly pass two paths on your left (only one is marked on the map) and reach a crossroads near an esplanade (Les Chabottes on the map). Turn right and then immediately left. About 100m further on, ignore a path on the right (not marked on the map) and continue uphill through the forest, which gradually becomes steeper. The path narrows and eventually emerges onto a magnificent rocky section offering a little view. The path turns sharply right between the rocks to reach the plateau at Pas de Saint-Vincent.

Yellow-green markings are scarce
(5) Head left, following a grassy trail that runs more or less along the pasture fence. A sign invites you to follow the fence (the markings on the map are no longer accurate). The trail climbs back up, staying close to the cliff. At the top, the trail moves away from the cliff and descends towards the valley. Pick up a path coming from the right and immediately leave the path climbing to the left. Continue straight ahead with the Croix de Pierre Chauve in sight. The path climbs for a few dozen metres and arrives at a crossroads.

(6) Turn right and follow the path down Combe Chaude for about 800 metres. When you reach a renovated house, go to the left corner of the building to find a signpost. Follow the path straight ahead, which runs along the left side of the building towards Barraquand. Stay on this path, ignoring a path coming from the left further on, and join a tarmac road. Follow the left-hand track, pass a house and then a second house with sheds, and stay on the road until the next crossroads.

Red and whiteGR®93signposting

Continue along the road on the right (about 150 m) until you reach the end of the field.

(7) Look for a faint path on the right and follow it. Go through a fence to find a much clearer path. After 500m between woods and pastures, you will arrive at Pas du Touet.

(8) Begin the descent towards Vachères. The descent is fairly steep and dotted with alternative tracks, which are often just shortcuts to cut the corners. Stay on the main path, ignoring all the tracks on either side, and you will come out onto a wide path at the Vachères signpost.

(9) Continue straight ahead towards Les Chichats and after 200m, when the path turns right, continue straight ahead on the trail. Join a tarmac road at the Les Chichats signpost. Follow it to the left towards Pont de la Pierre. Ignore all
private paths or tracks on either side to reach the D68 at the containers.

(10) Cross the road carefully to the left, crossing the stream, and immediately turn right onto Chemin de la Solane, which begins in front of the Peyrus sign. Shortly afterwards, take a road coming from the left, enter the village via Grande Rue and continue to the junction with Place des Tilleuls (not shown on the map).

No further signposts
(11) Turn right towards this square, cross the bridge and continue straight ahead along Montée du Pont (leave the road on your left after the bridge and Rue des Jardins shortly afterwards). When you reach the D68, cross again with caution and continue straight ahead on a path. At the fork just after the house, follow the path uphill to the left. When the path levels out, you will see a statue in memory of the resistance fighters on the right. Continue for another 150 metres and look for a path on the left.

(12) Follow the track that descends to the left between the fields towards the Chapelle Saint-Pierre. Follow the boundary wall on the left and at the end, turn right to enter the cemetery. Cross it and exit through the main gate to return to the car park (S/E).

We did this circuit in very hot weather. The route is well shaded except on the ridges, so it was perfect. The climb is long and steep, but once you reach Pas de Saint Vincent, it's truly magnificent, and a little cardio is good for you. At point 6, we made a round trip to Pierre Chauve, at the cross, which is a climb but worth it for the views of Col du Tourniol, La Bataille and Mont Blanc. On the way back, the descent is steep in places, so I recommend using walking sticks.
A physically demanding hike, but no tricky sections

A very beautiful hike, but in my opinion it should be rated as difficult given the very steep climb up to the ridges, which could discourage some hikers. I got a little lost on the plateau trying to find the trail between points 5 and 6, so I cut across the fields and trees to find my way back. Finally, at point 6, the building appears to be inhabited and the owners have put two electric fences across the path. Being in trail mode, I didn't bother to check if it was possible to open them, but to my knowledge it wasn't, so I jumped over the first one and crawled under the second... Otherwise, nothing to complain about, a superb walk with a nice elevation gain and some very beautiful views.

A magnificent hike, very varied and offering beautiful views.
The climb up to the ridges is DIFFICULT: steep gradient over a relatively long distance.
The descent is complicated by slippery leaves, stones and roots. I would therefore advise against hiking after rain, or at least bringing walking sticks.
I plan to do the hike again in the opposite direction to enjoy a gentler climb.
(At the summit, instead of turning off to descend immediately as indicated in the description, we climbed up to the cross, which I highly recommend for the view, especially of Léoncel).

A superb hike that is well worth the effort.
The climb up to Pas de Saint Vincent is tough, you have to hang on and stay motivated, but the view at the top is breathtaking. I don't regret the effort.
I'd happily do it again.

Hello, lovely hike. When we arrived at the Pas de St Vincent, there was a beautiful view of the Ardéchoise mountains. We extended it a little. We didn't go through the village of Peyrus. We turned right at Loziere. It was 18 km and 1,100 m of elevation gain

We left on Saturday at 9:00 a.m.
It was a beautiful day, a little hot in the valley but very pleasant at higher altitudes.
It took us 7.5 hours, including a half-hour snack break and the climb up to the Croix de Pierre Chauve.
The explanations were excellent!
The effort of the long climb at the start is rewarded once you reach the plateau with a magnificent panorama.
The climb to the Croix de Pierre Chauve is well worth the detour.

Great hike, we left at 7:30 a.m. because the forecast was for 35°C, and sure enough, we finished at 5pm and it was incredibly hot. With 10 kilos on our backs for training, it took us 7.5 hours, excluding long breaks, to finish the trail because tractors working in the fields forced us to continue along the trail to the end until we reached the road and then back down.
Apart from that, it was a beautiful route, and we were treated to some stunning views and some tough going! Thank you!

Beautiful hike. Countless varieties of wild orchids, all beautiful. Very steep climb from point 4, classified as difficult at this level. The same applies to the descent from 8 to 9. Walking sticks are essential. Proper hiking boots are absolutely necessary. The path is very rocky on the way up. From point 6, the road is not very long, but the path at point 7 is very difficult to see. While chatting and not paying attention, we ended up adding an extra kilometre to our hike! If possible, activate the alerts on your phone, which will sound if you stray from the route. Then turn them off, as they can be annoying! The GPS track on the IGN map is very reliable. I recommend leaving the track when you are on the ridge after point 5 and climbing up along the ridge, occasionally crossing the electric wire marking the boundary of the land. At the top, you can rejoin the track at point 6. The view is well worth it!

Nice hike in the snow, unfortunately no view because the weather was foggy.
The climb is a bit steep, especially on black ice.
The trail was essential for finding our way between 5 and 6: the snow had covered everything, including the footsteps of other hikers.
It took us 6 hours, including a lunch break, and the snow was above our knees throughout the higher sections.
The hike would undoubtedly be easier in dry weather.

Good description, a little more complicated to follow between points 5 and 6 on the plateau, as the tracks are more or less visible...
Otherwise, I would describe it as difficult, due to the steep gradient between points 4 and 6.

We followed the route on the plateau only.
There were no loops, but we climbed up to the Pas de St Vincent via the hamlet of Les Mottes and descended via the Pas du Touet, with a car waiting at the finish.
In this sense, finding the trail just below the Pas de Saint Vincent was a bit tricky, as we had to feel our way because it was poorly marked where we arrived.
The descriptions of this hike are spot on when it comes to finding your way around the plateau, thank you!

A very beautiful hike with superb views. The climbs are steep, that's for sure, but that's what allows you to leave the valley and find yourself above Léoncel, with a totally different atmosphere in no time!

A great challenging hike, you can go without hesitation. There was fog when we arrived, so we'll have to come back another time to enjoy the beautiful view. The hike is very well described, so a paper map is still the safest option. You can also use the GPS track, which is very handy, but unfortunately you're not immune to your smartphone breaking down.
