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.

The Suc de Sara is a summit of volcanic origin located at 1,521 m. No surface volcanic activity has taken place on this peak, but it was created as a result of an underground magma chamber 6-8 million years ago. Fragments of concentric rings are all that remain to suggest its existence. From this summit, the view is magnificent.
