The lava tunnels in Reunion are becoming an essential activity on the island. There are very few places in the world where it is possible to have such an experience. During this underground exploration you will discover a universe worthy of Jules Vernes. The Piton de la Fournaise offers us this opportunity. The instructors who will supervise you will be happy to explain to you how these famous lava tunnels form and will share with you their passion for volcanology through this "volcanic speleology".

During this short approach walk your instructor will give you a description of the landscape around you. After the first explanations given by your guide, the time that your sight is done in the dark, you will discover a unique universe. Ceilings from which melting dark chocolate seems to flow (stalactites), benches of lava, forests of stalagmites, a "dodo", a "shark" ... And much more if you let your imagination run wild. It is a unique journey that we offer you. Very often standing, sometimes bent, from time to time squatting you will progress slowly, at your own pace. After 2 h 00, you will leave this environment of anthracite gray, brown, red and black while having another look at the Piton de la Fournaise.

5.00It was a great experience that can be experienced in few places in the world. Our guide before very open and answered all questions friendly. The security measures were more than adequate. Knee pads, helmet, flashlight, gloves, were provided. Sometimes we only made progress on all fours, but that made it very adventurous!

5.00A sensational experience thanks to LUDO our guide of the day. He shares his knowledge with passion and makes us participate in his speech by making us reflect on the formation of the tunnel, its history, the different formations of the flows, botany... and his personal anecdotes all with a humorous touch. I recommend it without hesitation++++ if you want to have a good time and learn about one of the volcanoes, see the most active volcano in the world.
Great visit

5.00A very enjoyable, exciting way to learn more about Réunions history as a volcanic island. Fred enthusiastically shared his knowledge with patience and humuor, making this a fun adventure. He also made sure to balance the French/English translation well in a group where everyone else was French. Highly recommended!!
