Capricornia Cays National Park includes eight islands formed from coral fragments, which rise just a few metres above the high tide mark. Their biological diversity, exceptional beauty and the endangered plants and animals they protect make them internationally significant. The cays and nearby coast support the largest breeding population of endangered loggerhead turtles in the South Pacific.

A large percentage of all seabird species in the Great Barrier Reef visit each year. Anchor in the sheltered lagoon at Lady Musgrave Island. Go reef-walking, snorkelling, diving, birdwatching, boating or fishing. Camping is permitted on three of the eight islands. Purchase permits in advance. Seasonal closures protect breeding seabirds, turtles and vegetation.
