Please check location - campground is just into national forest on route 12 (from the east) about 10 miles along from route 89 junction.
Campground is about 1mile up a forest road - signposted from route 12.
We were only people there and seemed very quiet.
About 9 sites of which half are easy to get level.
Clean drop toilets.
Quite a tight loop so not recorded for larger vehicles / trailers.
Really enjoyed staying there apart from a smart mouse who broke into campervan and kept us awake at 3am !
One of the best places to stay in the park. Access to great hiking right on doorstep; e.g iceberg lake, ptarmigan and Grinnell glacier.
Very short walk across road to the Inn which has a decent shop, restaurant and pay ($2.50) showers - the inn has rooms and cabins.
Also short drive from the main park lodge with dining, bar (great cocktails!) and activities.
Sites next to river are great. Sites are level and wooded.
Busy in peak times - large campground was full by about 4pm in days we were there (late August)
Zion is a wonderful park and recommend staying somewhere on the shuttle route so you will not need your vehicle.
South Campground is easy walking to Visitor Centre.
We found the campgrounds level and well sized. Decent shade. Large campground.
Relatively small state park. Great area with the dunes very close. Facilities were clean.
Note that since the dunes are popular with off-road ATVs etc there will be some noisy traffic until the evening - not too loud.
Good RV spot in good location, a bit dearer than others
Good shade, near the river. Level sites. Was not too busy when we were there late July. Clean showers / toilets. Dearer than other options (we had the cheapest sites - others are dearer) but pluses make up for that.
Good service from the team there.
