Limestone apostles crumble into furious surf while the road clings to cliffs above.
Limestone stacks crumble into the Southern Ocean in geological real-time; one apostle collapsed in 2005 while tourists watched. The road clings to cliffs above, carved from rock by returned soldiers as a memorial to their mates. Every bend reveals a different ocean.
The Great Ocean Road runs for roughly 240 kilometres along Victoria's south-west coast and was built by returned servicemen in the years following the First World War as a memorial. Limestone stacks and arches along the Port Campbell coast continue to erode, while plaques and walking routes interpret a shoreline known for hundreds of shipwrecks. Inland, the Otway Ranges add temperate rainforest, waterfalls and walks among myrtle beech and tree ferns.
Solo
Drive in short sections with fatigue managed, using formed lookouts and inland walks to break up the coastal road.
Couple
Share cliff lookouts, lighthouse country and a slow overnight route rather than racing between headline stops.
Friends
Take turns driving and leave room for surf towns, short walks and weather changes along the coast.
