Landscape
New Caledonia’s main island, Grande Terre, is long and mountainous, with ridges dividing eastern and western coasts. Offshore islands include different limestone and coral landscapes. A large reef system encloses extensive lagoon waters.
Mountain interiors and mining areas contrast with mangroves, beaches and low coastal plains. The lagoon is a major geographic feature in its own right rather than simply a fringe around the land. The Loyalty Islands have a different relief from Grande Terre.
