Christmas Island boasts endless miles of spectacular wall diving and magnificent marine life. This small island is full of natural wonders and a unique travel experience.

Shallow waters with fringing reef surround the island, before plunging dramatically into the depths of the Java Trench, the Indian Ocean’s deepest point.

It has a unique natural topography and is of immense interest to scientists and naturalists due to the number of species of endemic flora and fauna which have evolved, and is often referred to as the ‘Galapagos of the Indian Ocean’.

Each year at the beginning of the wet season (Oct-Nov), an estimated 43 million red crabs begin a spectacular migration from the forest to the coast to breed and release their eggs into the sea, with baby crabs returning approximately one month later. The spawning season brings in the large pelagic visitors such as whale sharks, one of the diving highlights here.

Most visitors island hop to include a visit to Cocos (Keeling) Islands.
