There were 4 stops on our cruise over 10 days (the stops were in the middle of the journey with a few days out at sea either side leaving/getting back to Sydney). I have to say that I think the water and beaches in Lifou were the best of all of them! Crazy blue and a lot of sea life around. While in Lifou we also went on a tour of the forest and a grotto where we were able to see a coconut crab (pictured above). For your information, the coconut crab is the largest land-living anthropod in the world and it's basically a massive hermit crab that stops wearing a shell once it reaches adulthood.
Mare is another island in New Caledonia and it was our last island stop on the trip - we had an absolute blast with a solid beach crew - more of our antics can be see in the video I made (here) on my youtube channel.
