Macquarie Island is a UNESCO World Heritage Site due to its major geoconservation significance. It is the only island in the world that is entirely composed of oceanic crust and rocks from the mantel. The unique diversity of the island makes it a truly remarkable place to visit. Sand Bay is located on the east coast where you will find Royal and King Penguin rookeries as well as Southern Elephant Seals, and if the weather permits, you will have the opportunity to get closer on a Zodiac®.
