  • I think it's the most beautiful part cave depth 120 m, 800 steps down (a lift go back us, phew...) huge rooms with huge columns (looks like piles of plates) arrived at the bottom of the cave we are witnessing a sound and light, wonderful, amazing, not to miss this site it is a must

  • A very good experience the descent into this aven thanks in part to the excellent guide that we had. I recommend also the Museum which is very well made and beautifully complements the visit of the Chauvet Cave

  • Here is the most beautiful and largest stalactite cave which I've ever seen. The system is connected with a beautiful Museum. Everything is well organized and there are plenty of parking spaces available. Absolutely stunning!

  • Walking from a very hot, bright, summer's day down 180 meters into this cold, damp grotto was just the thing for our holiday in the South of France. It was difficult to get a feeling of perspective so far down in the cavern because it was so enormous ... just the first cavern was big enough to hold a 12 story building and then we walked down stairs to another, lower cavern with even more fantastical formations that take literally thousands of years to form. This portion of the grotto open to the public is only about 20% of the total underground space. It was formed millions of years ago by an underground river flowing through the limestone, which itself was formed by layers of coral reef living and dying at the edge of a prehistoric ocean.
  • Very modern support buildings with museum. The caves are impressive - a Land train takes you back to start as cave exit a good distance away. Local restaurant slightly pricey but good. Cafe poor!
  • Extremely beautiful cave with thousands of stalagmite and stalactites big and small. The tour is also very informative. The park itself had good atmosphere.
  • Amazing. Guide knew her stuff. Interactive prehistoric museum afterwards was also a plus
  • Very impressive cave with a path straight through the middle. Superb closing with light and sound show in the reg chamber.
