Puy de Dôme

The highest of the Chaîne des Puys, a line of about 80 extinct volcanoes in the Auvergne, which form a UNESCO World Heritage Site with the Limagne fault. From the summit, at 1,465 m, you can see the row of volcanic cones and craters stretching away.

Reach the top on the Panoramique des Dômes rack railway, or walk up the old Roman path (about 1 hour). There are the ruins of a Roman temple to Mercury at the top, and paragliders launch from it. Vulcania, a volcano theme park, is nearby.
