Volcanism in the Massif central has its high spots from the Puy de Dôme to the Gerbier de Jonc, as well as famous crater lakes like Pavin and cliffs of columnar basalt like those bearing the old city of Saint-Flour.

In the past, observation of these great sites led to the birth of vulcanology, but now specialists examine the smallest details of regional volcanic areas. In their footsteps, you will find unexpected wonders, like the "ice fountains" or the underground lake in the Creux de Soucy.

You will be surprised to learn that the Ardèche has some of the youngest volcanoes in the country and that telluric fires gushed out far to the south, in the Languedoc, right to the open sea.

For the first time, the volcanism of the Massif central is dealt with as a whole and shown as never before, from its prestigious summits to its most intimate expression.
