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.

Mont Mézenc offers an exceptional 360° panorama over the entire Massif Central and the Alps to the east. From the south of Mézenc, a large part of the South-East of France is visible up to Ventoux.

Magnificent panorama. The climb is very easy. Two options are available to you, via the Col de la Croix des Boutières or via the Croix de Pecata. The latter is shorter, but less pretty for my taste.

From this side of Mont Mézenc, you have an incredible view of the departments of Ardèche and Haute-Loire. You are also precisely on the watershed line.
