The best way to experience the wonder of the Great Barrier Reef is by getting under water. Scuba diving and snorkelling from Cairns and Port Douglas is a magical experience and there are tours catering for beginners and experts alike.

Get up close and personal with colourful tropical fish, swim alongside beautiful coral reefs, and explore the dazzling array of marine life that the Reef offers. For deep dives and open water, head for the Outer Reef. If you’re after a more relaxed experience, or if you have kids, check out the Inner Reef and Marine World options.
