The Nîmes-le-Vieux Trail showcases a variety of typical Causse Méjean landscapes: stony arid hillocks; a few hollows of deep soil overlaid with winding plough lines; steep promontories looming rampart-like; and vast stretches of craggy rocks, whose shapes fire your imagination and captivate you.

This ruiniform block field (felsenmeer) on the Causse Méjean has resulted from the capricious dissolution of the dolomite limestone. It emerges suddenly, like a final panoramic viewpoint before the abyss of the gorges that delimit the Causse.
