Christmas Island

The approximately 85-square-kilometre national park covering the central plateau and coastal areas of Christmas Island, protecting the island's tropical rainforest, limestone karst formations, coastal cliffs and adjacent marine environment, with the red crab as a keystone species.

A remote, undeveloped turtle-nesting beach on the southeast coast of Christmas Island, accessible by a rough track through the plateau forest and one of the most pristine stretches of coastline remaining in the Indian Ocean.

The main settlement, harbour and entry point of Christmas Island, a steep volcanic Australian territory in the eastern Indian Ocean where the rainforested plateau drops directly into the sea.

The spectacular northern sea cliffs of Christmas Island where the volcanic plateau plunges abruptly into the Indian Ocean, creating one of the most dramatic coastal landscapes in the eastern Indian Ocean and an important seabird nesting site.

The annual breeding migration of an estimated 50–120 million Christmas Island red crabs from the plateau rainforest to the coast, one of the most spectacular animal migrations on Earth.

A deep limestone cave on Christmas Island formed in the island's Phosphate Ridge, featuring stalactites, a collapsed sinkhole and a natural rock bridge where the ceiling has been worn through by centuries of water erosion.
