Christmas Island

#australiatrip Christmas Island is most famous for its annual red crab migration, often described as one of the most extraordinary natural events on Earth. Every year, millions of bright red crabs emerge from the rainforest and march to the ocean to spawn. Roads, beaches, and forests are covered in a moving sea of crabs, creating an unforgettable spectacle. Park rangers help manage traffic, ensuring safe passage for both crabs and visitors. In addition to red crabs, Christmas Island is home to blue crabs, robber crabs (the world’s largest land crab), and countless other unique species that make this island a biodiversity hotspot.
