Experience a breathtaking underwater wonderland

Snorkelling and diving are the most popular ways to see the Great Barrier Reef with those doing it for the first time preferring to walk into the water from an island or a large pontoon, while others enjoy swimming out from the back of a boat. Non-swimmers can see the Reef on a semi-submersible, glass bottom boat, or helmet dive, while a scenic flight offers an impressive view.  If you are looking for something different try stand-up paddle boarding around a Great Barrier Reef Island or zooming along on an underwater scooter.

Some of the more exciting Great Barrier Reef activities include swimming with dwarf minke whales, a night dive with sharks, diving alongside giant potato cod, snorkelling with a turtle and spotting where Nemo lives. For a longer Great Barrier Reef experience choose a live-aboard boat trip, stay at an island resort or spend the night on a pontoon. Dive courses are available if you want to experience a number of days and nights scuba diving.

Cairns & the Great Barrier Reef operators are passionate about their World Heritage area and will teach about its amazing marine life. Many have marine biologists on board who can give you a personalised tour, and some have citizen science programs where you can contribute to research on the Reef.
