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

The ancient Vestide du Pal volcano is what is known as a filled-in maar crater! Measuring approximately 1,700 metres in diameter and 150 metres deep, it may well be the largest maar crater in Europe.
This route will take you along ancient Roman roads that link the valley to the plateau, passing through various vegetation zones.
As well as this first volcano, there are two others to discover along the way: Lac Ferrand (a maar filled with water) and Le Chambon, the latter of which has been completely eroded.
A volcanic hike, then...

Description of the walk

On leaving Montpezat, on the D536, take the small road on the right leading to the hamlets of Le Mas and Le Fau. Park at the first bend: there’s space for two or three vehicles.

(S/E) Retrace your steps to the main road, then turn right onto it and follow it for 50 metres. Leave the road and turn right onto the gently ascending track (passing in front of a farm) for 150 metres.

(1) After the farm, turn left onto a track winding its way uphill beneath the chestnut trees. The slope, which is steep at first, becomes gentler further on as it veers westwards.

(2) At a junction, leave the path leading down to the hamlet of Le Fau on your right and continue climbing along this track: it is a magnificent ancient 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 junction.

(3) A vast panoramic view lies behind you, facing east! Take the track on the right, which climbs gently for 150 metres. At this point, at the fork, continue straight on towards the north-east; the track on the right will be used for the return journey. Walk first beneath the fir trees and then through open countryside (enjoy the views to the right). At a junction of four tracks, stay on the main one – which is well signposted – and carry on straight ahead to the ‘Les Oulettes’ signpost.

(4) Turn left onto the small tarmac road for 150 metres, then leave it to take a path on the left (under a canopy of conifers) which rejoins the road a few hundred metres further on. Take the road again on the left until you reach the Cros du Loup junction.

(5) At the junction (hiking signpost), head down the path immediately to the left – which is initially steep – following theGR®® (red and white markings) andGRP®® (red and yellow markings) routes.

(6) From the Croix du Pal junction, you have been walking along the eastern and northern slopes of the Vestide du Pal volcano. At this point, you enter the crater. You’ll join the small road you’ve already crossed. Let it branch off to the left, and continue due south along theGR®® and GRP®® path. Shortly afterwards, ignore another path branching off to the right. You will then follow the very young Fontaulière stream, which has its source here and flows through Montpezat before joining the Ardèche.

(7) At the junction, for a round trip, turn right at a right angle, cross the stream and head north-west up a rather difficult track: the volcanic rocks are particularly unstable. Ignore two paths branching off to the right, pass under the high-voltage power line to come within sight of Lac Ferrand.

(8) This lake is private; it belongs to the nearby Domaine Ferrand. Depending on the time of year (tourist season or not), you may (or may not) be able to walk all the way round it. In any case, refer to the information boards on site. It is also an ancient volcano. Retrace your steps.

(7) At this point, just like the Fontaulière stream, you are emerging from the Vestide du Pal crater. Turn right to follow the stream south-westwards and join the D 536. Follow it to 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. Pass through this hamlet, continuing due south to reach the Croix du Pal junction.

(3) At the crossroads, follow the track to the left for 150 metres, then turn right onto a gently sloping, pleasantly shaded forest track offering superb views. Follow this track, ignoring the various small paths branching off.

(9) After a wide bend, take a path on the left, which descends steeply, at times quite abruptly. You are now in the scree of the third volcano: the Chambon. Keep a close eye out for the markings on the trees; this path, which often winds in hairpin bends and crosses several small streams, takes you to the hamlet of Le Fau.

(10) Walk through the hamlet and, as you leave, take the path on the left. You’ll cross a small road; continue straight on along a gentle, pleasant slope through the meadows.

(1) Carry on straight ahead, then turn left twice to return to your car (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.
