Costao de Itaipu - Arraial do Cabo

Heron Island isn't about deep dives or big pelagics. Instead, we love it for its quiet, shallow beauty, a proper coral cay experience right on the Southern Great Barrier Reef. The maximum depth is a gentle 16 metres, making it perfect for longer bottom times and really soaking in the details. On a good day, visibility pushes past 15 metres, letting the light filter down through the water, illuminating the vibrant Transverse and Galaxea corals. Keep an eye out for Blue-spotted Stingrays resting on the sand, or the quirky Double-ended Pipefish trying to blend into the rubble. We’ve found the best time to dive is early morning, before the day boats arrive, when you might just have a school of Longfin Bannerfish all to yourself. It’s a site that rewards patience, a place to slow down and appreciate the smaller wonders.
