Lonely Planet review

Take a 35-minute guided tour round the Grottes de l'Observatoire, a prehistoric cave network stuffed with stalactites and stalagmites, 279 steps down inside the hillside; strangely, it's the only cave in Europe where the temperature rises as you descend. Admission to the cactus collection and Musée d'Anthropologie Préhistorique is also included.

From the tourist office, take bus 2 to the Jardin Exotique stop.
