These two volcanoes, Haute-Loire twins to the Jaujac crater, are characterized by their well preserved shape. The Petit Suc is a particularly fine example. Its height is 1272 meters. The Grand Suc, only about  20 m higher, has a chipped cone. It emitted a lava flow that poured into the Holme Valley down to Goudet. The walk among trees has a pleasant forest atmosphere and will enable you to see beautiful volcanic cross-sections at the quarry.
