Mont-Gerbier de Jonc

Discover the source of the Loire

Longest river in France, the Loire begins with three unassuming springs named Authentic, True and Geographic.  The climb to the summit of Mont Gerbier de Jonc, most famous peak in Ardeche, does not look very challenging but you still need to be physically fit and wear suitable shoes to reach the summit, 1551m above sea level.  But it is well worth the effort for the breathtaking 360° panorama over the volcanic scenery.  For the ultimate spectacle, climb the peak in time to watch sunrise.

A volcanic environment 

From Gerbier de Jonc, you can see the silhouette of Mont Mezenc, an unmistakeable pyramid rising to more than 1754 metres on the watershed line.  Another example of the area’s volcanic scenery is the Ray Pic waterfall that tumbles over basalt ‘organ pipes’ not far from Mont Gerbier.  It is one of the longest lava flows in France, but remember that swimming here is forbidden.  Look out too for Issarles lake that sits in an ancient volcanic crater.
