Stayed here with my family of 6 in June, 2020.  We arrived on a Saturday and we have a huge tent so the owners gave us part of the Small Group Site.  On the map it is the second little drive-in to the right in the Small Group Site.   This was right up against the rocks to minimize wind on our tent.  We were able to put the majority of the tent under the trees to keep it cool and shady.  

The bathrooms were adequate, though one of the men's showers was closed.  You can stretch your shower time ($3 for 5 minutes) by shutting the shower off while you lather as that time doesn't count and doing that 5 minutes was plenty of time.  The showers could use a little TLC and a paint job, but they were fine for all of us with good water pressure.

Campground was extremely quiet, which was nice, and the kids loved climbing the mountain behind us.  Of course it's within 2 minutes of the Canyonlands entrance which makes it incredibly convenient.  I've stayed in the Canyonlands campgrounds, and they are nice, but the bathroom and showers is great when you're traveling with teens and toddlers.

Also convenient to have the store there for extra ice, even though it's understandably expensive ($5/bag).
