Experience the Splendour of Australia's Great Barrier Reef

This sprawling coral reef system is one of the most biologically diverse places on the planet. You can spend a lifetime exploring the Great Barrier Reef and still not see all of this colourful coral realm—it’s nearly the size of Montana.

Sprawling off the east coast of Queensland, Australia, the Great Barrier Reef is not a single reef but a group of more than 2,800 distinct entities. It stretches over 1,250 miles (2,000 kilometres) north to south and covers some 135,000 square miles (350,000 square kilometres) in total.
