When you come in from either the North or South on Sheep Bridge Road, you have a choice of going down one of the spurs which has anywhere from 5-15 campsites typically. Sheep Bridge Road is in great shape, but the spurs have some ruts in them. Easily passable with 4WD and even probably 2WD when not wet, but have to slow to a crawl over some of the potholes. Easy to get into Hurricane for supplies if needed, but still feels very remote.
These sites have the most incredible views of the mountains, plateaus, and ridges around the Hurricane/Zion area. A lot of the sites aren't very level and not intuitively laid out with the views and where the firepit is placed.
This particular spur has a trailhead at the end so there's a handful of cars going down to check that out but nothing major.
