Sentier de la serpentine

The trail is named after the serpentine because the subsoil of the moor, through which the trail passes, is made up of serpentine, a low-acid rock unlike the granite of the region. It is a zebra-shaped rock that looks like reptile skin. The trail will take you to the serpentine barrens of Saint-Laurent, which represent very original ecosystems and contain a biological heritage of great rarity. You can discover it, thanks to an interpretation trail whose main theme is pastoralism. Interactive supports allow visitors to discover the natural and historical wealth of the moor. The site is classified Natura 2000.
