The cays’ stunning white beaches and coral reefs will leave a lasting impression. Their exceptional beauty and biological diversity make them internationally significant.

Capricornia Cays National Park's eight islands are part of the Great Barrier Reef World Heritage Area. Their biological diversity, exceptional beauty and endangered plants and animals are internationally significant.

The stunning white beaches and outstanding coral reefs of these small, relatively untouched cays make them popular destinations. This national park offers a variety of recreation opportunities ranging from commercial resort relaxation to nature-based camping and day visit enjoyment. Unlike rocky continental islands, the Capricornia Cays were completely built by corals.

Rich forests of Pisonia grandis, which are typically only found on coral cays, dominate the island vegetation. A fringe of tough, small trees and shrubs such as coastal she-oak, octopus bush, native grasses and pandanus surround the cays' pisonia forests. On North West Island, strangler figs and native elms are scattered through the forest, and native mulberries, sandpaper figs and lantern bushes grow in small clearings.
