Just got back from 2 days at Capitol Reef. Wow is the scenery at this park beautiful! Plus it's all very low key and uncrowded in comparison with Bryce and Zion. There's no traffic, no parking issues, and very few people on the trails. I hiked the Hickman Bridge trail and the Capitol Gorge trails starting each at about 8 AM. I had each of the trails to myself, not seeing another soul until I was just about back to the bottom of the trails.
The park was hot at mid-day. This is a good time to visit the Visitor Center, pick your own fruit at multiple orchards, see petroglyphs, and stop at the historical Mormon school, store, and blacksmith shop.
About 1/2 hour before sunset, drive down the 1 mile road to Sunset point. The scenery and the varied colors of the landscape at that time of day are breathtaking. It's amazing how far you can see, plus deep down below you is the Sulphur Creek gorge.
