Top Réunion Island Services

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".
