Grotte de Clamouse
Just before reaching St-Guilhem-le-Désert, on the left of the road, you'll find la Grotte de Clamouse. Apart from ancient sediments, stalagmites, and stalactites, you can admire a lot of 'younger' sediments in this cave that are 'only' a few thousands of years old and therefore still sparklingly white. The 'Couloir blanc' and the 'Salle des excentriques' are genuine jewels with delicate and rare cristallisations.
