The mighty 12 Apostles are world-recognised icons of the Great Ocean Road. These giant rock stacks soar from the swirling waters of the Southern Ocean and are a central feature of the spectacular Port Campbell National Park that extends from Princetown to Peterborough. The dramatic and imposing limestone cliffs that are the backdrop to the Apostles tower up to 70 metres, while the tallest of the rock stacks is around 45 metres high. The Apostles had their beginnings up to 20 million years ago with the forces of nature attacking the soft limestone of the Port Campbell cliffs. The limestone was created through the build up of skeletons of marine creatures on the sea floor. As the sea retreated, the limestone was exposed.
