What is the Christmas Island Red Crab Migration?
The huge migration of red crabs on Christmas Island is one of the Earth's most amazing natural phenomena and has to be seen to be believed.
Every year, millions of large crabs emerge from the forest and make their way to the ocean to breed. The migration begins with the first rainfall of the wet season which sees the crabs swarm across roads, streams, rocks and beaches.
This natural event is Christmas Island’s biggest tourist attraction, and each year draws hundreds of nature-lovers from all over the world to witness it in person.
It is a truly spectacular sight that even world-famous naturalist Sir David Attenborough called one of his greatest TV moments.
Need to know
To watch the migration and spawning head to Drumsite, Flying Fish Cove, Ethel Beach and Greta Beach. In order to protect the crabs, some sections of roads may close for part or all of the day during the peak migration time. Crab bridges are also built over the roads which can serve as great viewing platforms to stand and watch the flow of crabs.
