We spent four days here for spring break this year while exploring Zion NP. It’s basically just reserved, dispersed camping with outhouses. That said, you are much more spread out than the free dispersed camping around the park.

The good:

• The views were amazing right at our campsite.
• There was a fair amount of privacy with everyone spread out through the field.
• Proximity to Zion (40 minutes to the park entrance or just up the road for some hiking)

The mixed:

• There are outhouses but they can get fairly full before they get cleaned. They were full when we arrived but cleaned a couple days later.
• The wind. You are on a plateau with little cover. The winds were coming from the south when we were there so you can try and find a spot with some protection.
• The road is rough, both up to the campground and within it. Take it slow and you will be fine but it can be a bit intimidating. I would be concerned trying it when wet.
