New Caledonia might be part of your cruise itinerary in which case you will probably visit not just one but probably two or three of the islands. The main island with the capital Noumea is called Grand Terre, and to the west are the Loyalty Islands, with Lifou and Maré probably being the best known travel destinations. The Isle of Pines (Île des Pines) is particular attractive to honeymooners.
New Caledonia is a bit special in the sense that it is an overseas collectivity of the French Republic which makes it part of France but not the European Union. Consequently, the official currency is not the Euro but the Pacific Franc (which is however strictly linked to the Euro). There are strong political currents which push towards total independency but I think we will need to wait another couple of years to see these movements come to fruition.
The climate is tropical and warm, with trade winds ensuring that it never gets too hot or uncomfortable. The ecosystem is unique and offers many species found nowhere else in the world, in particular plants, birds, turtles and reptiles.
New Caledonia is not a cheap destination, and in particular Grand Terre is well developed and highly industrialised. You will instantly notice the huge nickel mine not far from the city centre, and I can assure you that you will be stuck in a Renault and Citroën traffic jam in no time. It’s a different story on the outlying islands where Kanak culture is still very vivid and local languages are spoken at least in the domestic environment.
