When you're at Capital Reef, there is a scenic turnout just west of the park a bit, on the south side of the highway. The sunset there with the light bouncing off of the reef is awesome. I did it twice while in the area, on one sunset the clouds were just right to make it THE most beautiful sunset I've ever seen. And I've seen some dandies.
The critters on the highway were quite busy on departure from the overlook, be forewarned.
While there, I camped in Tory at the hostel/campground, frugal, clean, nice view, friendly owner, and REAL GREEN grass. They also have a washer and dryer, came in handy. It was in 2005, so info may no longer be accurate.
Make sure you do UT 12, I prefer heading s/w, better views of the Grande Escalante
Have fun.
