Discovery of the lava tunnels - Flow 2004

The Piton de la Fournaise is impressive, but why not see what's going on in its bowels? Enter the heart of this fiery giant and follow the lava flow of 2004. At 6 kilometers long, it is considered the longest lava flow ever discovered on the island. Don't panic: during your visit, you'll explore "only" 2.5 km. A unique experience that plunges you into an exceptional mineral universe with an unusual underground landscape. From the surprisingly metallic-grey vitrified walls to the lava stalactites and stalagmites, Simon and his associates will teach you how to appreciate this unique place... and how to preserve it.

By limiting group size, they guarantee a quality experience, but also the preservation of the lava tunnel and the tranquility of the site. Beware... perd pas ou dan fénoir!
