Hwy 12 is like a six lane SoCal freeway compared to where I'm from. Just time it right over the top. Plenty to see and do, and photograph down below either side in the meantime. I do believe, however, that it was a staggering mistake to classify 12 as a formal Scenic Byway. About twenty motels suddenly sprang up in the tiny little town of Torrey just outside Capitol Reef, with naive investors thinking it was something like a Grand Canyon or Zion Springdale business opportunity, not realizing the remoteness of the location over a high pass. Most of those venues remained empty, with doors and windows swaying in the wind, for years. Damned touristification anyway! The clay hills just outside the other end of Capitol Reef got all chewed up with ATV tracks. Still, Capitol Reef is amazing spot, and one of the least visited NP's having direct highway access. Hwy 12 is also the starting point for many classic canyoneering hikes; but some of those too are getting a little overused due to the proliferation of web videos, GPS coordinates, and so forth.
