The Loyalty Islands is in New Caledonia.
Each of the Islands has its own unique beauty.
With out some basic understanding of the French Language its makes it difficult to get around on any of the Islands. Apparently some Japanese is spoken according to signs at the Airport in Ouvea and Lifou. Local dialects on the Islands are different with some commonality between Lifou and Mare, but not in Ouvea.
Generally a hire care is a good option, Lifou and Mare have hire cars at the Airport although a car be hired from other vendors and organised to meet you at the Airport and be dropped off at the Airport
The islands' beautiful water is prime for snorkeling and swimming. Jinek Bay, a natural marine reserve, along with Jokin Bay on the northern shore of Lifou are stunning in their coral and marine life including sea turtles.
On the Islands various accommodation is available ranging from Hotels, Gites, Tribal accommodation and camping. Most Gites, which are bungalows run by local tribes offer a camping option. Dinner at the Gites and camping is best organised in the morning so that they can cater for you.
