The Chastel-Marlhac plateau

Two viewpoints offer panoramic views. Discover the plateau on the PR trail: La table basaltique de Chastel.
A veritable citadel of lava! From a geological point of view, its origin is uncertain: it is either an ancient lake of hardened lava (a paléolac), a mound detached by erosion from the neighbouring planèze or an ancient lava flow.
Naturally defended by high basalt cliffs, this plateau has always attracted man. Archaeological discoveries testify to a Celtic presence, then to a Gallic oppidum that became a Roman stronghold.
