Well known as a scenic coastal drive, a large portion of the road hugs the coastline. However, besides just coastal views, there are many other interesting stops along the way.
Lorne, a beach town popular with tourists, has other attractions including nice forest walks as well as Erskine Falls, a pretty waterfall not far from Lorne.
Further down, you'll drive through the Great Otway National Park, housing temperate rainforests and temporarily hiding the coast from view. There is also Cape Otway Lighthouse, Australia's oldest operating lighthouse till it was decommissioned in 1994.
And as you go further westward along the Great Ocean Road, there are other rock formations besides the Twelve Apostles : Island Arch, Blowhole Gorge, and London Bridge (which has fallen down) etc. And of course, lots of beaches.
So, when you do go for the Great Ocean Road drive, do it slowly and enjoy the journey!!
