Mont Gerbier de Jonc, Saint-Martial

4.5
#9 of 14 in Nature in Ardeche
Mont Gerbier de Jonc is a mountain of volcanic origin located in the Massif Central in France. It is made of a type of rock called phonolite. It rises to an altitude of 1551m, and its base contains three springs that are the source of the Loire, France's longest river. It is the second most-visited site in the département of Ardèche, after the Ardèche Gorges.Mont Gerbier de Jonc was formed 8 million years ago when a volcano erupted molten phonolite lava. The lava was too viscous to flow far and it cooled to form a lava dome of phonolite rock in the crater of the volcano. The lava dome has columnar jointing, which formed during cooling of the lava. The volcanic cone containing the lava dome was later eroded away, exposing the lava dome.

  • Excellent view if you (like me) that the climb, you will not see the sources of the Loire, because they are not on the mont itself but in the surrounding area.

  • "The Loire has its source at Mont Gerbier". We have not visited the different 'real authentic sources"around Mount, but preferred the climb to the top. Both say frankly it is stiff... Must take are time, put your hands over some passages uphill as downhill. Some strings are arranged to allow the overcoming of most difficult passages. You don't have to be a mountaineer however but it takes knowledge that mounted is not obvious. But the view worth the effort. An absolutely must visit and a place where we will return, even if it means taking a detour.

  • Great location, beautiful views, the route to the top, the atmospheric gift shop. There is also a restaurant and a picnic area. Toilet and many parking lots for campsites. It is worth to visit this place and temporarily takes more than we expected, you must spend at least 4 hours.

  • A hike that is accessible to all, being well shod, magnificent view at the top, and down another path. Superb.

  • The Mont Gerbier de ring is located on the (beautiful) road which crosses the massif of Mézenc-Gerbier between Le Monastier on Gazeille (rated high Loire) and Vals Les Bains (Ardèche). The ascent of the Mont Gerbier is short, but steep. You can see also the sources of the Loire and the shops of regional products installed at the edge of the road. The parking is free.
