From the highlands of Aveyron to the doorsteps of Gaillac area, the Ségala Tarnais offers to the visitor an amazing variety of soils and landscapes: in the north, the Ségala itself, vaste primary plateau notched with deep gorges; futher south, beyond the Cérou, change of scenery! Here are the first whitish outcrop of the scalloped limestone plateau, of which the platform overlooks the albigensen’s basin.
