Sable Chief Rocks is a natural rock formation rising from the nutrient-rich waters of Gladstone Harbour, on the doorstep of the Southern Great Barrier Reef. While less famous than the outer reef cays, this spot offers a unique snorkelling experience among rocky ledges and shallow gutters where coral colonies and reef fish congregate. The harbour's sheltered position means generally calmer conditions than outer reef sites, though water clarity varies with tide and season. It's a quiet, off-the-beaten-path option for those seeking a different perspective on the reef's southern reaches.
