The perimeter of the site
The central zone of the site, defined with the help of people from the universities of Clermont-Ferrand and the PNRVA, covers an area of 242 km². It includes all the geological and landscape features showing outstanding universal value, and is designed to ensure their protection.
There is also a discontinuous buffer zone, notably at the border between the Chaîne des Puys and the Limagne fault, and on the western side of the Plateau des Dômes. Its principal function is to protect the surrounding area and preserve the main view points over the volcanic alignment.
