Highway 12 from Bryce Canyon to Torrey is in my opinion the best road in America for spectacular views. Done the above 89 and 89A many many times and it is nice also but not the overwhelming ride you will have on Hwy 12 to Torrey. Torrey west to Hanksville, South to the Moki Dugway and Mexican Hat (Hwy 261 or "Trail Of the Ancients") will certainly never be forgotten. It should be on everyones "Bucket List" if you ride. Check it out. Word of caution: do not ride the Moki Dugway if it is raining.
89/89A South of Kanab to Fredonia and then on to Page has the best views. 89 is just so so IMO.

I drove this route about 10 years ago in the winter and it was spectacular. Ever since I have wanted to return on something other than a car!! Another great route I have taken is State route 14 from Cedar City to US 89 and then branch out from there where ever!! Thanks for the reminder of this great route.
