A Unique Volcanic Formation

Mont Gerbier de Jonc is an extinct volcano, formed about 8 million years ago during the volcanic activity that gave rise to many of the Auvergne's landforms. What immediately strikes visitors is the mountain's distinctive shape, often compared to a hump or a “jonc” (a term referring to a marsh herb). This unique silhouette is due to the nature of the volcano, a suc (phonolitic volcano) whose highly viscous magma solidified rapidly, forming a rocky mass.

The main rock that makes up Mont Gerbier de Jonc is phonolite, a dense, resonant volcanic rock whose name means “stone that rings.” When you strike these rocks, you can hear a metallic sound, which is an added attraction for amateur geologists and tourists interested in natural phenomena.

The Source of the Loire

Mont Gerbier de Jonc is best known as the source of the Loire River. This majestic river, which flows more than 600 miles through France, originates on the slopes of the mountain. There are three main sources identified at the foot of Mont Gerbier de Jonc, each with a small stele or sign indicating their importance. These springs are fed by rainfall that seeps into the volcanic soil and emerges as small streams. Visitors can take a short hike to reach these springs and contemplate the first drops of water that, after a long journey, will end up in the Atlantic Ocean.

Hiking to the summit

One of the main activities for visitors to Mont Gerbier de Jonc is climbing to the summit. The climb is relatively short but quite steep, requiring good physical condition and suitable footwear. The well-marked trail winds through vegetation and volcanic rocks, gradually offering increasingly spectacular views of the surrounding landscape.

At the summit, the panorama is exceptional. On a clear day, you can see the Alps, the Massif Central, and even Mont Ventoux in the distance. The view of the surrounding mountains, the Ardèche plateaus, and the valleys is simply breathtaking. It is an ideal place to recharge your batteries and admire nature in all its splendor. Photography enthusiasts will find plenty of opportunities to capture breathtaking landscapes.

Fauna and Flora

Mont Gerbier de Jonc and its surroundings are home to a rich and varied fauna and flora. The mountain climate and altitude create an environment conducive to specific biodiversity. Botany enthusiasts can observe rare plant species, some of which are endemic to the region. These include wild orchids, gentians, and mountain pansies.

The fauna is also diverse. It is not uncommon to encounter marmots, chamois, or even foxes while hiking. Birds of prey, such as falcons and harriers, often soar above the ridges, adding to the wild atmosphere of the place.
