Documents may mention the presence of a "mountain of fire" in the southeast of the island as early as the 17C, but the first account of anyone climbing the volcano did not appear until over a century later. Although easily accessible nowadays, the Piton de la Fournaise remains one of the world's most active volcanoes. It isn't particularly dangerous and regularly provides a fascinating spectacle of the elements in all their fury: its ramparts provide superb observation points during eruptions within the Enclos caldera.
