It was great! Wear pants and a t-shirt with your shoulders covered. Bring a small backpack that contains water. Our guide, Frank, was very nice and he knew a lot about the lava tunnels and also the plants and birds of the region. And afterwards, there were drinks! Fantastic.

Volcanic underground exploration!

Frank is passionate and makes the athletic hike in the lava tubes of the 2004 flow absolutely fascinating. There are no mandatory crawling sections, but there are three that you can do, which vary the challenge. Overall, the course is varied and led at a pace accessible to most people.

A unique experience.

We experienced a moment out of time accompanied by a guide who lives his passion to the fullest, and who shares it with complete simplicity; we really appreciated the format that Vincent proposed to us. I recommend him very warmly if you want to discover the depths of the volcano in a small group 👍🏻

Lava tunnels with the family

We did the 2004 lava tunnel outing, accessible from age 5, with our 6 and 9-year-old children and had a great time. Total duration of almost 4 hours with 2 hours 30 minutes underground and we didn't see the time pass! Everything is provided in terms of equipment and the guide takes care of taking souvenir photos, which is great because you can really enjoy the moment. Vincent is a brilliant guide, a true enthusiast who shares his knowledge in a super fun way for adults and children alike. We will certainly ask to have Vincent for a future volcano excursion on Reunion Island!

Operator response

Merci beaucoup Carole pour ce chouette retour si détaillé ! Quatre heures d’aventure avec deux jeunes explorateurs de 6 et 9 ans, sans voir le temps passer : voilà qui résume parfaitement une sortie réussie 😊 J’ai été ravi de vous accompagner et de voir toute la famille profiter pleinement de la découverte. Je tiens aussi beaucoup à prendre les photos pendant la visite, afin que chacun puisse rester concentré sur l’expérience et repartir avec de beaux souvenirs. Merci pour votre confiance, votre curiosité et votre bonne humeur. Ce sera avec grand plaisir que je vous retrouverai lors d’une prochaine excursion volcanique à La Réunion ! Vincent du Bureau Rando Volcan 🌋🇷🇪
