That looks like an AWESOME place to ride!!! Reminds me a LOT of Big Bend -- we rode there about a year and a half ago. We were COOKING in mesh gear in February! LOL!!
The upside is, you take the Interstate west for about an hour and pick up Hwy 24 south to Hanksville and that will take you toward Capitol Reef Nat'l Park and Hwy 12 through Dixie Nat'l Forest.
12 is one of THE best bike roads anywhere! It has many spots where you can't pull over because there's a steep dropoff on both sides of the road!
