The neck of Seautres is a basaltic piton resulting from a volcanic eruption dating from about 8 million years ago, in the Coiron massif. At 150 metres high and 200 metres wide, it is the largest in Europe. It sits majestically above the village of the same name, Seautres, which is a small agricultural village barely bigger than a hamlet. Lovers of hiking, you will be amazed by what nature can shape.
