Leaving Rochechouart, drive towards Chéronnac, home to the source of the Charente! Follow its course to the Videix lake for a refreshing break. Pass through Saint-Gervais and see the buildings made of impactite stone, a rock formed by the fusion of meteorite (which crashed over 200 million years ago) and local minerals. In the hamlet of Pers, you'll find a stork well. Back in Rochechouart, you'll cross La Graine on the Roc du B?uf Roman bridge. This tour passes through part of the Périgord-Limousin Regional Nature Park.
