I visited the Chaîne des Puys during a trip along the enchanting Dordogne. We drove up the highest peak of the chain, the Puy de Dôme. From there you have a fabulous view over the whole chain that is quite impressive. There are dozens of vulcanos of different shapes: domes, maars and cones like the wonderful Puy Pariou. They are not very tall volcanic formations but I have never seen so many in such a small area.
