Here are a few nominations:
I have driven the coastal road, very similar to California One, that runs between Sao Paulo and Rio de Janeiro in Brasil, regretably not in a Pagoda! Spectacular scenery, and a number of quiet vacation spots and secluded beaches becon one to take a restful pause from the road.
Skyline Drive and the Blue Ridge Parkway from Front Royal, Virginia to Gatlinburg, Tennessee is simply a great drive - not fast, but barrels of fun! My wife and I did the whole length a few years ago in our M.G. TF and it is on the list to do again in the Pagoda! One could drive straight through in a couple of days if one wanted, but we took almost 2 weeks, there was so much to see and do along the way. Then once in Gatlinburg, it is only a hop, skip and a jump to a little stretch of road known as the "Tail of the Dragon," which boasts something like 300 curves in 13 miles!
