Some really amazing roads having breathtaking views have already been mentioned. But, I'll add my two cents by mentioning the one road I have actually traveled on and surely can vouch for. So, Fellas! Here, I present to you one of the most amazing road trip places in the world.

The Great Ocean Road

Great Ocean Road: The Great Ocean Road is an Australian National Heritage listed 243 kilometres (151 mi) stretch of road along the south-eastern coast of Australia between the Victorian cities of Torquay and Allansford.

I have been to Melbourne and you go there, you must drive once on this road. It's not very far from Melbourne. You can see some pretty amazing views alongside Great Ocean Road including Twelve Apostles.
