Large rhyolite boulders scattered over the headlands and beaches are a reminder of volcanic activity millions of years ago, as are volcanic plugs and other striking rock formations found in the park.
Cape Hillsborough National Park covers 1012 hectares in size & is one of the most ruggedly beautiful parks on the Central Queensland coast. Lowland rainforest and vine forest grow along creeks, valleys and hillside gullies. Rocky hills and headlands support open eucalypt forest and a grassy understorey, while patches of low heath survive on exposed slopes. West of the camping area a large mangrove community is an important breeding ground for marine animals.
