Diving in Heron Island & Capricorn Group
Heron Island is a coral cay on the southern Great Barrier Reef where you walk off the beach into a reef, and the Heron Bommie, Gorgonia Hole and the Coral Cascades are a few minutes by boat. Turtles nest on the beach from November to March, reef sharks and rays patrol the harbour, and mantas visit the cleaning stations in winter. Wilson, Wistari and One Tree islands are nearby.

THE LOCAL PLANNING BRIEF
Understand the options around Heron Island & Capricorn Group
Queensland research starts with the departure region. Cairns and Port Douglas, the southern reef islands, Townsville and the south-east coast appear in different parts of this directory. Treat them as separate trip choices: being in Queensland does not put every reef or wreck within reach of the same boat. Work from a proposed operator itinerary back to your accommodation and transfers.
What this regional directory records Counts describe published records, not bookable trips or confirmed open sites.
There are 38 published site records in Heron Island & Capricorn Group. The recorded categories include reef (17), pinnacle/bommie (6), wall (6), island (4). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Heron Island & Capricorn Group site cards to compare recorded access and depth, then open the individual pages for the map accuracy and source notes. Sites grouped in a region are not necessarily close enough to combine in one day.

How do I choose a dive in Heron Island & Capricorn Group?
Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 38 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
When should I visit Heron Island & Capricorn Group for diving?
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
Can I use these maps to enter or navigate a dive site?
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
