The panorama from the top of the Puy de Sancy opens wide onto Auvergne and its volcanoes, the silhouettes of which are visible on the horizon. The site, which is said to allow a view of 1/7th of France, attracts both sports adepts and volcanology enthusiasts. Over an accessible and limited surface, the area of the Chaîne des Puys houses a particularly linear, complete, diverse, and educational volcanic complex that makes its international reputation.
