La Vestide du Pal in Montpezat-sous-Bauzon - Three volcanoes circular

The ancient Vestide du Pal volcano is what is known as a filled maar crater! Approximately 1,700 m in diameter and 150 m deep, it could be the largest maar crater in Europe.
This route will take you along ancient Roman roads that connect the valley to the plateau, passing through various levels of vegetation.
In addition to this first volcano, there are two others to discover along the way: Lac Ferrand (a maar filled with water) and Le Chambon, which is completely dry.
A volcanic hike, then...

Description of the walk

On leaving Montpezat, on the D 536, take the small road on the right leading to the hamlets of Le Mas and Le Fau. Park at the first bend: there is space for two or three vehicles.

(S/E) Retrace your steps to the main road and turn right for 50 metres. Leave the road and turn right onto the slightly uphill track (passing in front of a farm) for 150 metres.

(1) After the farm, turn left onto a track that winds upwards under the chestnut trees. The slope, which is steep at first, becomes gentler as it veers westwards.

(2) At a crossroads, leave the path leading down to the hamlet of Le Fau on your right and continue climbing this track: it is a magnificent old Roman road in excellent condition. Follow it for several kilometres, crossing a few streams (easy fords). The climb becomes steeper towards the end, with long hairpin bends, leading to the Croix du Pal crossroads.

(3) Enjoy the spectacular panorama behind you, facing east! Take the track on the right, which climbs gently for 150 metres. At the fork, continue straight ahead to the north-east; the track on the right will be used for the return journey. Walk first under the fir trees and then across open ground (enjoy the panoramic views on the right). At the intersection of four tracks, stay on the main track, which is well marked, and continue straight ahead until you reach the Les Oulettes signpost.

(4) Take the small tarmac road on the left for 150 metres, then leave it for a path on the left (under coniferous trees) which rejoins it a few hundred metres further on. Take it again on the left until you reach the Cros du Loup crossroads.

(5) At the crossroads (hiking signpost), descend the path on the left, which is steep at first and is also aGR® (red and white markings) and aGRP® (red and yellow markings).

(6) From the Croix du Pal junction, you will walk along the eastern and northern slopes of the Vestide du Pal volcano. At this point, you will enter the crater. You will come to the small road you crossed earlier. Leave it on your left and continue south on theGR® andGRP® trail. Shortly afterwards, ignore another trail leading off to the right. Then follow the young Fontaulière stream, which has its source here and flows through Montpezat before joining the Ardèche.

(7) At the crossroads, for a return trip, turn right at a right angle, cross the stream and climb north-west on a fairly difficult track: particularly unstable volcanic rocks. Ignore two paths branching off to the right, pass under the high-voltage line to arrive within sight of Lac Ferrand.

(8) This lake is private, belonging to the nearby Domaine Ferrand. Depending on the time of year (tourist season or not), you may or may not be able to walk around it. In any case, refer to the signs on the ground. This is also an ancient volcano. Retrace your steps.

(7) At this point, just like the Fontaulière river, you will exit the Vestide du Pal crater. Turn right to follow the stream to the south-west and join the D 536. Follow it on the left (do not cross the bridge) for 20 metres, then take the small tarmac road on the left leading to the hamlet of Le Pal. Cross this hamlet, continuing south to reach the Croix du Pal crossroads.

(3) At the crossroads, take the track on the left for 150m, then turn right onto a slightly downhill forest track with pleasant shade and superb views. Follow it, ignoring the various small paths that branch off.

(9) After a wide bend, take a path on the left, descending steeply, sometimes abruptly. You are now in the scree of the third volcano: Le Chambon. Look out for the markings on the trees; this path, which often winds its way through several small streams, will take you to the hamlet of Le Fau.

(10) Cross the hamlet and, at the exit, take the path on the left. Cross a small road and continue straight ahead on a gentle, pleasant slope through the meadows.

(1) Continue straight ahead, then turn left twice to return to your vehicle (S/E).

The first part of the hike is indeed interesting. The rest is not the kind of trail that appeals to me and that I want to hike, but there's something for everyone. There are no technical difficulties except perhaps in the last part, which is a short distance along what looks like a riverbed. Be careful at point 9, the path on the left is not very visible and is not marked. It does not look like a hiking trail, so if you miss it and cross the stream, turn back as it is a dead end. The path is used by cows, so watch out for "mines"🤣. Classified as difficult due to its distance, that's the only reason I can think of. Circular in 7 hours including breaks, walking at a normal pace. That said, at this time of year the trees are bare, which allows you to enjoy the magnificent view.

A long hike, very interesting in the first part. It's a shame you can't get close to Lake Ferrand, which is completely fenced off.

A pleasant hike, really interesting in its first part, namely the climb up the old Roman road dotted with sculptures and bas-reliefs in places.
The rest of the hike is not particularly interesting, and the lake is completely closed off.
The duration and difficulty ratings are incorrect. It took us less than 5½ hours, without pushing ourselves and with several breaks along the way. The hike does not require any real effort. I imagine the difficult rating is only due to its length.

The designated car park is difficult to access and very small. With the farmer's permission, we parked in front of a farm building. We climbed up the paved slanting street through the slag heaps as recommended by A Claudin, but the descent would have been difficult on the way back. The climb was less difficult than expected. The "official" signage is good but only indicates the villages, and the numerous forestry tracks require frequent thought in terms of orientation. The vegetation cover makes the Chambon volcano difficult to identify, but the views from the summits allow you to admire the Vestide maar with its secondary cones and the Beauzon knoll. Wildlife abounds and spring flora is timid.

The only downside was that to park, we had to return to Montpezat and park in the first public car park, as the indicated location was inconvenient (private access roads, fences).
Otherwise, it was a lovely walk, mostly shaded on the way up, which was pleasant given the heat and sunshine, with a beautiful view at Vestide du Pal. Less difficult than advertised.

A beautiful hike, but sometimes lacking in discoveries compared to what else can be seen in the region.
The start of the climb is a bit steep and there is no shade, but once you get past this section (20 minutes), the rest is easy going and not monotonous.

A very pleasant walk, with lots of forest but magnificent views and a few interesting sights to admire.
Please note: the small car park on the Fau road is now fenced off and closed by a gate and is inaccessible.
Thanks to the author of the information sheet.

We did the circular loop anticlockwise, climbing up the volcanic passages and descending via the Roman road. We found this direction easier because the slag and very loose terrain are easier for us to climb. Furthermore, the very steady descent is easier on the knees and allows you to admire the remarkable work of the Romans over long stretches.

The tour of Lake Ferrand is currently prohibited by numerous signs warning against crossing the fence.

We chose to go via the summit of knoll du Pal at 1,400 m via a very clear path, which gave us a beautiful view of the entire Pal crater (the GPX track is available on request).

The only tricky part is parking, as there are not enough spaces available (you have to park on the road).

The only slight downside is that parking can be a bit tight, especially in summer, so you have to be careful not to get in the way of the farmers' work.

We completed it in 6.5 hours because there was a very cold north wind, but the hike is very well described.
Thank you.
