A safe lagoon, sheltered bays and numerous uncrowded anchorages make the Caledonian lagoon a true paradise for sea lovers. 


In 2008, part of this lagoon was listed as a World Heritage Site, a true sanctuary of exceptional marine biodiversity. It is the second largest reef complex in the world with the presence of one of the rare "double reef barriers" and the existence of important nesting sites for marine turtles.
