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/

One of the most beautiful viewpoints in the region with the village of Borée, at the foot of the Sucs and Mont Mézenc

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.

A volcano in the shape of a needle of cooled lava, Le Gerbier de Jonc, placed like a cone on the Ardèche plateau, is with the Gouléïou, located in the Cirque des Boutières, the archetype of the phonolitic juices of this territory. From the Gerbier de Jonc and the surrounding phonolite reliefs, rises the longest river in France: the Loire. Trails of varying difficulty and length lead to the summit.
