Nice and quiet spot
Stayed here for a night and didn't have any issues with rafters or boaters, etc. There's not a lot of traffic either. Right on the river bank and it is refreshing water.
Great stop leaving Arches
There's a bathroom and water, decent spot sizes and more great views.
Ease of camping
Showers, ferral dogs, lots of flies, close numbered spots, and lots of traffic noise. Everything camping shouldn't be. There are great views and some hiking trails around it, though.
Middle between Zion and Bryce
Great spot on Harris Rim that overlooked the canyon. There's some traffic noise but not too bad. There is a herd of cows that range up there as well.
