Situated off the coast of Praslin, Curieuse has a distinguishing feature: its red earth. Discovered in 1768 by the French explorer Marc-Joseph Marion du Fresne, it was ravaged by a fire in 1771 and then home to a leper colony of which a few vestiges still remain. Declared a national marine park in 1979, it is home to many underwater species, which can be discovered while scuba diving or snorkelling in the idyllic waters of the Indian Ocean. But above all, Curieuse is renowned for the hundreds of Aldabra giant tortoises that live there. It is highly likely that you will get the chance to meet these fascinating reptiles. Along with Praslin, it is also the only island on which the sea coconut grows wild.
