road trip down the "Great Ocean Road" ... rent a car, go driving, stop at pretty beaches and small towns along the way (Lorne, Apollo Bay etc); drink and eat at the local pubs
One of the most breathtaking views in Vietnam. I took the train from Danang to Hue (3hours) and even though it was rainy and foggy, it still looked beautiful. The hills of green meeting blueish waters breaking on red rocks and yellow sand beaches... Don't miss it!
