An amazing story

Here, you get to see the insides of the Volcan de Lemptégy, formed 30 000 years ago. At the end of the second world car, this site was chosen for the extraction of volcanic cinders for use in rebuilding the nation’s damaged town and cities.
The quarrying, along with the scientific work that took place alongside, revealed the internal structure of the Volcan de Lemptégy to the public.

An interactive experience

With your guide, you see the inside of the Volcan de Lemptégy, exploring the site’s fascinating geology. And you can even get your hands on real volcanic rocks!
Along the way, you’ll take in incredible views of the 80 or so volcanoes of the Chaîne des Puys – the Volcan de Lemptégy is right in the middle of them.

On the last part of the tour, you even get to see the old machinery that for 60 years was used to extract the pozzolana stone: scalping green, riddles, trommel and various grinders and crushers.
