With 1000m of altitude, the Méjean causse opens on a vast yellow grass steppe, attractive as are the deserts. Its landscapes, strewn with hamlets to the typical roofs of roofing stones and shelters for the shepherds, undulate ad infinitum. The causse of Sauveterre is a less arid calcareous plate, with the rather broken landscapes in its south-western part. It is skirted by the Valley of the Batch, area the most fertile, called "nourishing earth" of Lozere.

This valley crosses the department of west in is, of Canourgue to the mountain of the Narrow part (Lozere Mount), where the river takes its source. The historical vestiges, the castles, fortresses, churches, mark out this valley tortuous and laughing with the landscapes as varied as peaceful.
