From the Middle Ages to the Iron Age, a descent in time and an ascent on the causse. From the Templar and Hospitaller jewel of Ste-Eulalie de Cernon, get to the Oppidum of Puech du Mus.

An archeological site discovered on the western edge of the Larzac Causse, the Puech du Mus refers to a Celtic oppidum of the 5th century BC. Overhanging the high Cernon valley, it offers a 360-degree panorama on Ste-Eulalie, the Larzac causse and, on the horizon the Cevenol peaks. If the path is steep at the start, the oppidum and the landscape are well worth it.
