The Gorges du Doux owe their name to the river that flows through them. The name is misleading: the river and the gorges have a wild, even tumultuous aspect! This valley will amaze you with its diversity: river, forest, relief, pastures… This exceptional space has also been classified as a sensitive natural area (Espace Naturel Sensible) since 2015. Discover different atmospheres depending on where you are! In the middle of the valley, stop in the characterful village of Boucieu le Roi and walk to the banks of the Doux river. It is hard to imagine that this modest watercourse can overflow its banks, but one must always be wary of still waters: the floods of the Doux are terrible! Besides, it is said that the name "doux" (soft) was given to moderate the relentless character of the river…

The Tchier de Borée is a contemporary artwork situated in the heart of the volcanic landscapes of the Boutières region. Created in 2008 by Fabienne Versé and Serge Boyer, this megalithic installation comprises 70 standing stones arranged in a circle 80 meters in diameter. Each stone bears a symbol or message: runes, astrological signs, natural elements (air, water, fire, earth), winds, mythology… The word “Tchier” (from the local dialect) means “pile of stones”: a tribute to stone, time, and the memory of the land. https://www.montagnedardeche.com/patrimoine-culturel/tchier-de-boree-2634/

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.
