The park combines natural coral reefs, historic shipwrecks and purpose-sunk artificial reefs. Several sites blend all three, such as The Elbow, where natural reef meets wreck structure. The Christ of the Abyss statue at Dry Rocks adds a distinctive artificial feature to an otherwise natural reef setting. This variety means divers can shift between reef ecology and wreck exploration within the same trip.
