Topissimo tour of the caves of 2004, the guide was really great. The difficulty is really very slight. Thanks to the protections provided, there is really no risk

An extraordinary experience with a guide, Frank, whose kindness is matched only by competence. A magical moment, an extraordinary discovery at the height of the intense island. Thank you, a thousand times thank you.

Very good discovery with Vincent, very good explanation. He put sindy, my wife, who was a little afraid to go into these tunnels and everything went very well. We recommend without hesitation

Great experience and very much worth the money! All the safety equipment is provided, and the guides are all experienced volcano explorers. Our guide Franck was lovely and telling us lots of interesting things about the rock formations, the volcano and the island's nature.

Very cool experience. Our guide was not only highly experienced, but also super nice and telling us interesting facts about the tunnels, volcano, biodiversity on the island and anything else we wanted to know. Highly recommended! Be sure to follow the clothing recommendations (long trousers and a t-shirt) to avoid random scrapes on legs or shoulders.

A great team and a great experience! Thanks to Fred for sharing his passion and Vincent for helping me get the photos back from the release. For those who read the comment, I had already done it alone but the experience is much more rewarding with a guide...don't hesitate!
