We were lucky enough to get tickets for the visit by storm lamp in the evening. We had a great time, was quite an experience, especially when we turned the lamps out briefly to watch the strange glowing of the crystalline formations. The tour was all in French however we got the gist and the guide did come and explain the key points to us too (the only English speakers on the tour), he was very good, funny and clearly knowledgeable. The caves aren't massive but they are packed with amazing formations and tunnels and tour was just over an hour. Highly recommend.
