Home to the Twelve Apostles, this world-famous stretch of Victorian coastline has a base of limestone formed 10 to 20 million years ago – an accumulation of layer upon layer of the skeletons of marine creatures. As the ocean level fell, the limestone was exposed and the pummelling wind and waves sculpted it into caves, arches and blowholes, leaving towering stacks marooned just off the coast. The erosion process continues: the former London Bridge formation collapsed in 1990, and more recently two apostles have crumbled (seven remain). The apostles are still a breathtaking view from the cliff-top, and you can climb down Gibson Steps for a view from the beach.
