Great Barrier Reef
Cairns is the closest gateway to the Great Barrier Reef - the world's largest, most spectacular coral reef system. You can swim, snorkel, dive and sail the World Heritage-listed Great Barrier Reef, a living masterpiece so big it can be seen from outer space.
Here you can discover a whole new underwater world and greet over 6,600 species of flora and fauna, including 1,500 species of fish, 4,000 species of molluscs and 400 yptes of coral.
There are a multitude of tours & cruises activities available, including snorkelling, introductory or certified scuba diving, and live aboard dive courses. If you prefer to stay dry, there are spacious pontoons, semi submersibles and glass bottom vessels that allow you to explore this natural wonder without getting your hair wet!
