Playful discovery of the formations that make up this exceptional site. The outing is divided between exploration and explanations on the construction of the tunnel and its original formations, as well as the functioning of the Reunion volcano (according to your expectations). Understand by having a fun time!

Magical tour, made very interesting by the explanations of our guide. Botany, geology, vulcanology are no secret to Jocelyn. The tour is full of discovery and within reach of any curious and motivated person and child. Perfectly secured framing will delight young and old.

Amazing morning with Jocelyn! He put us in confidence, he briefed us well on safety! These explanations and anecdotes are very interesting! An exciting and passionate guide, concerned about the environment in which we operate. The course is adapted to the group with narrower passages or not! There are always two choices The equipment provided was of good quality! We were a small group (8) which is not the case for some groups we met! Moreover, after comparing, they remain one of the cheapest, for an incredible visit! Thanks for the punch at the end! I highly recommend!

Great experience with our children aged 10 and 12 Jocelyn is a well of knowledge that he gives as the activity progresses. The visit is beautiful. We loved it! We highly recommend Jocelyn and Profundo! It only takes small groups which makes the experience very enjoyable. Two days later. We hiked the furnace stud and all the information Jocelyn could give us was very useful to understand and appreciate this hike even more!
