When in Melbourne, YOU MUST SEE THE 12 APOSTLES at the Great Ocean Road! It is actually a three hours drive from CBD which is not bad at all. The Scenery was spectacular! I did not regret waking up early and driving off 3 hours. It was a great experience 🙂
Also, on the way to the 12 Apostles, you may also drive by the Loch Ard Gorge, Gibson Steps, Island Arch and Port Campbell. But I believe there’s more you would be able to go around and enjoy the scenery.
