The Great Ocean Road in Victoria is supposed to be one of the great drives in Australia (and it is), however I reckon the Black Spur drive between Narbethong and Healesville would have to be up there as well. Driving through the awesome tall timber and stunning tree ferns is a sight to behold. Did this video on the way back from doing some 4WD driving today.

If you have any video of drives through spectacular scenery please share.
