The Gouffre de Padirac is an incredible cave system containing an underground river and gorge and a huge cavern. Underground lakes and pools and stalactite formations all add to its appeal but somehow it is the sheer size of the caverns that is really incredible.

Once you get into the cave system, they don't want you taking photos and the low light does make it difficult, so I didn't. While very commercialized, it is worth the visit. Make sure they know you're an english speaker and they will do their best to team you up with a guide that also speaks english.
