The Twelve Apostles dominate the home stretch of the Great Ocean Road. Once there were twelve of them, today there are only eight, but they're still a sight to behold at sunrise and sunset. If you don't want to stand in the car for hours, you can walk down the Gibson Steps to a lookout for a unique perspective. You can also take a short walk along Loch Ard Gorge, a beach dotted with limestone stacks. Another must-see is the Grotto and London Bridge, two unique limestone structures.
