Mont Gerbier-de-Jonc is one of the highest peaks of the Monts d'Ardèche in the south-eastern Massif Central. The mountain itself is a striking, extinct volcanic cone with a good view over the Massif Central. The ascent and descent require some fitness and good footwear. There are a few short climbing rocks that cannot be avoided. But the view is worth it.
