Located in the south of the island and rising to over 2,631m, the Piton de la Fournaise is one of the most active volcanoes in the world. Its vast massif occupies about one third of the island.
Since its eruption in 1998, which continued for nearly six months, it has seen several eruptions a year. Access, however, is relatively easy by road from the Plaine des Sables, which leads to Bellecombe Pass, an opportunity to witness projections and frequent lava flows. Once there, a gorgeous view overlooking the Enclos Fouqué and Formica Leo opens up. It is worth noting that each eruption changes the configuration of the area. Though the overall landscape is set in a dominantly mineral state, once the lava eventually cools, a natural process of vegetation is established, giving birth to a very diverse ecosystem of fauna and flora.
The Piton de la Fournaise has been continuously monitored since the establishment of a volcano observatory. In October 2019, the Piton Fréri came into being, a new volcanic cone that appeared after the last eruption.
