What to do

There are many ways to explore and see the stunning Great Barrier Reef’s outer reefs. You can spend a full day or even weeks seeing this natural wonder of the world exploring underwater, on a boat or from a bird’s eye view.

  • Snorkelling

    Snorkelling is a very popular activity people do when visiting the Great Barrier Reef. Snorkelling allows you to look below you and spot the tropical fish, the colourful coral swaying, and other sea creatures. When you book a tour, there is a brief introductory class before you set off to a reef to snorkel on your own.

  • Scuba diving

    Scuba diving allows you to go deeper into the water and swim along with any of the sea creatures you see. There are tours available which include a complimentary scuba dive, or you can include one at your own cost. On the tours, you can be a beginner and have a brief introduction class or you can be a certified diver.

  • Helmet diving

    Helmet diving allows you to walk along the bottom of the Great Barrier Reef on the seabed. Watch as all the sea creatures swim by you as you walk by the colourful coral.

    Helmet diving is available on some Great Barrier Reef tours so make sure you book it the experience during your next visit.

  • Glass bottom boat

    If you prefer to not get in the water, the glass bottom boat is the best way for you to still see everything the Great Barrier Reef has to offer. Either go on the glass bottom boat and watch the marine life below you or go in a semi submarine and watch how incredible life is underwater.

  • Scenic flights

    You can choose to go in a helicopter or a seaplane and get a bird’s eye view of the beautiful glistening blue water. On the flight, you see the different shades of blue, beautiful golden or white beaches, and the lush green hills on the mainland. On some scenic flights, you can see Heart Reef, which is as you guessed it, shaped like a heart!
