New Caledonia: Jewel in the Southwest Pacific
Considered the longest continuous and second largest in the world, the reef systems of New Caledonia have some of the most diverse concentrations of reef structures on the planet, providing a home for a vast diversity of species, including 2,328 fish species. It is an important site for nesting green sea turtles, and there are also large populations of dugongs and humpback whales. Pierre Constant shares his adventure.
