Worth a visit! - Nice to visit this cave. We did the Dutch audio tour. Once you arrive in the lower part of the cave, it is quite a climb back up! Definitely worth a visit!

A cave system to remember - If travelling on the A40 between Geneva and Lyon take a little detour to visit this attraction, We went mainly for the caves and what a fantastic couple of hours. The cave has many different formations, As the path drops down you come to a balcony atleast 100foot in the air which looks out onto the massive cavern, after desending you can either exit out or keep going down to enter the other cave tunnel which takes you to a look out platform in the middle of the cliff, coming back through the cavern to exit you see where you had first come from, Wow what a view.

Good. - It was good, yes I thought it was very interesting and actually good. At first I thought it wouldn't be good but finally it was good I think.

Small nugget - Very beautiful discovery magnificent cave. And a special mention for the welcome thank you all. Superbly maintained place I congratulate you.

To see - Incredible caves to visit absolutely! To do as a couple or family. Be careful temperature at 4 degrees down...

Caves - Beautiful caves and thanks to the audio guide on smartphones, I was able to follow the evolution of the cave. To do again with my little girls.

Wonderful! - Very pretty! I highly recommend visiting! Wear shoes that don't slip to make sure they don't fall, it's wet can eventually slip if we don't have a shoe that doesn't hold.

Superb family visit - A superb unique experience thanks to the kindness of Hervé. The caves are beautiful, we came this day as a family, with our 2 children (Arthur 4 years 1/2 and Robin 3 years) they were able to follow without any problem, there are many steps but they are safe for children with the barrier. We will gladly come back to do the Things to do on site next season. See you soon

Great. - A place to see, worth it, very nice cave and great workshop with family. We spend a full day on top, recommend

Good idea for children - A good idea for children, less for adults... Guides are willing. There are still a lot of steps to climb before the finish - it’s a bit painful.
