The Great Ocean Road -- which hugs the coast from Torquay through Anglesea, Lorne, Apollo Bay, Port Campbell, and Peterborough, until it ends at Warrnambool -- is one of Australia's most spectacular drives. The scenery along the 106km (66-mile) route includes huge cliffs, ocean vistas, beaches, rainforests, and some incredible rock formations. The most spectacular section is the 27km (17-mile) stretch between Princeton (the start of Port Campbell National Park) and Peterborough. The settlements along the highway are small, but they offer a number of accommodations.
The main attractions are in the coastal Port Campbell National Park, so don't be surprised if you're not overly impressed until you get there. If you are traveling on to Adelaide, you could stop off for a night along the Great Ocean Road and spend another night in the Coorong in South Australia.
