Reach one of the Great Barrier Reef's most pristine coral cays — a true bucket-list immersion where turtles, reef sharks and thousands of tropical fish surround you the moment you wade in.
What to expect
A scenic 45-minute high-speed catamaran from Gladstone Marina delivers you to this 16-hectare coral cay encircled by 24 km² of protected reef. Drift snorkel above staghorn coral gardens teeming with hawksbill turtles and leopard sharks. Guided dive packages pair you with PADI-certified resident instructors who know every bombora and bommie. Non-divers can join a guided reef walk at low tide with a marine biologist narrating the ecosystem underfoot.
Good to know
Ferry departs Gladstone Marina at 11:00 AM; confirm the return sailing aligns with your all-aboard time. Pre-book the ferry and any dive packages directly on the Heron Island website — spaces are strictly limited. Bring reef-safe sunscreen; standard sunscreen is banned on the island.
