Les Balmes de Montbrun - Mirabel

Le Coiron is a wild basalt plateau. On the southern side, near Saint-Jean-le-Centenier, troglodyte dwellings were built in the medieval period in the basalt cliffs of Montbrun.
From Saint-Gineis-en-Coiron, a small road winding across the plateau takes you to Mirabel, where you can enjoy magnificent views from the keep.
The only downside is that two-thirds of the route is on paved roads, although there is very little traffic.

Description of the walk

200 metres from the hiking information sign, on the Route de Privas (D7) in Saint-Jean-le-Centenier, there are a few parking spaces at the junction of the departure and arrival roads.

(S/E) Follow the white and yellow signs on the D7, away from the village. At the first fork, leave the D7 and continue straight ahead into the housing estate. Return to the D7, cross it and turn right.

(1) Pass through the housing estate, still following the signs, and head towards "Basaltes, Jastrie". At the crossroads, follow the sign for "Jastrie" and continue straight ahead. The tarmac road quickly becomes a dirt track which will take you to Bas Montbrun. Keep following the white and yellow signs.

(2) In the bends, there is a beautiful view of the Claduègne valley, Villeneuve de Berg and Mont Juliau on the other side of the main road. In the background are the greenhouses of the Ardèche Cévennes and, in the distance, Mont Lozère.
Continue along the track.

(3) In the basalt cliff opposite and below are the openings of the troglodyte dwellings.
When you reach the first houses, take the paved slanting street on the left that descends towards Les Balmes. At the entrance to the street, there is a sign explaining the site.

(4) Brown painted signs invite you to descend to the left towards Les Balmes or the chapel. Don't hesitate to go down to Les Balmes, where there are numerous signs and information panels. On the way back, a path crosses towards the chapel and the site of the castle keep. Continue straight ahead after the chapel to join the Saint-Gineis-en-Coiron trail.

(5) Take the path downhill on your left (at the sign marked "chapelle"). Follow the path (north) marked in the trees until you reach the RD7, which you will cross (barriers). Continue straight ahead and descend to the river.

(6) Cross the Claduègne river via a footbridge, then turn right on the other side. Begin the climb to Saint-Gineis-en-Coiron. There are numerous hairpin bends, so pay attention to the white and yellow markings at the various junctions.
When you reach the first houses in the village, turn right and then immediately left until you see the hiking information sign under the church.

(7) Opposite the church (listed as a historic monument), turn left onto the road signposted "Mirabel Darbres". Follow this small tarmac road, which offers a wide view of the crops and livestock farming on the Coiron plateau. There were many birds of prey when we passed through in the spring.

(8) At the "Pas de Vendrias" signpost, at the fork in the road, turn left towards Mirabel. You can see Mont Redon in the distance. Signposting is sparse!

(9) At the Croix des Avias, continue straight ahead. The road descends towards Mirabel after passing Mont Redon.

(10) At the first hairpin bend, you can take a grassy path to cut the corners. Return to the road and continue in the same direction.

(11) At the next crossroads, Mât Mirabel, make a return trip to the tower overlooking the village of Mirabel. This tower, visible from many surrounding villages, is the only remnant of a medieval castle. It was restored in 1970 by its current owner.
Return to the mast.

(11) Turn right towards Saint-Jean-le-Centenier (5.6 km). The road runs along the basalt cliffs of Mirabel, climbs up and, from the transmission tower, descends towards Saint-Jean-le-Centenier, passing through the hamlet of Les Rochers with its houses built between basalt blocks.

(12) Continue through Les Hébrards and Le Moulin. On the other side of the bridge over the Claduègne, you can see the water channel leading to the mill. Final climb to the starting point (S/E).

Worth a visit

Don't hesitate to explore the Balmes de Montbrun site, continuing on to the viewpoint on the other side of the stream (wooden footbridge). You will find additional information in the Ardèche guide by the Geological Guides (Maryse Aymes and Jean-Pierre Esteban), discovery sheet on the Coiron volcanic massif - A wild basalt plateau by Maryse Aymes.

The village of Saint-Gineys-en-Coiron (or St-Gineis-en-Coiron) is well worth a visit. It has a 12th-century Romanesque church listed in the supplementary inventory of historic monuments.

Mirabel is another beautiful village worth visiting.http://www.patrimoine-ardeche.com/visite...

The first part of the hike is great, the Balmes de Montbrun are exceptional, but the second part is just road, nothing interesting

A lovely walk with a visit to this troglodyte village. An easy route, with random signposting but easy to follow with the app.
Quite a few sections along small, quiet roads.
Sunscreen and a hat are essential.

Superb route.
Personally, I don't find the paved road at the end of the route unpleasant. Especially since the beginning of the route is also paved until the end of the housing developments (which are rather ugly, by the way) and access to the balmes via an alternating gravel/stone path is relatively unpleasant.

However, we did the route in reverse because of the heat of the day, and this didn't cause any particular problems with the app and GPS.

We had a little trouble finding the way back from the troglodyte village, but that's just a minor detail!

A beautiful hike with stunning scenery and panoramic views.
We did this hike in reverse, with a slight change to the route.
When we arrived at Jarnias, we headed towards Mirabel via Les Rochers to avoid the tarmac. Before arriving at Mirabel, we reached the Baumier caves by following the dotted line on the map. It's definitely worth the detour.
While it's true that there is a lot of tarmac to contend with, it's worth noting that it's better to walk on the road than on the very stony path between the balmes of Montbrun and St Jean le Centenier.

A very beautiful hike with stunning panoramic views and two major points of interest: Les Balmes and Mirabelle.
However, there is far too much of the route on paved roads. We spotted a few parallel paths, such as those near Ventrias. But these paths are completely inaccessible as they are enclosed by fences.
The description should be revised to help those who prefer to start with the long paved section

Beautiful route, but it's a shame there's so much tarmac. However, in the Coiron area, it's difficult to do otherwise

A lovely walk despite the paved roads. We took the route in reverse, which allowed us to do the paved section in the morning. A quick visit to Mirabel is nice. Be sure to bring hats or caps in case of sunny weather!

A magnificent route. We discovered the Balmes site. The landscapes are varied. It's true that there are a lot of paved sections in the second half of the route, but that didn't bother us given the beauty of the landscape around us.
Thank you to whoever posted this route!

It's a shame that after Saint Gineys sous Coiron and all the way to Mirabel, the route is only on tarmac.

Departure from Mirabel.
Hiking on the road at the beginning and end breaks up the monotony.
Pleasant temperatures and flowers at this time of year.
