This private campground directly overlooks Carhenge and is not too far from (small) downtown Alliance. Although tent prices were listed, I’m not sure it would appeal to tenters. Prices range from $17 for tents to $27 for water to $35 for full hookups. 50% off after the third day. Weekly and monthly rates listed and it appears that credit cards are accepted. I believe there were four full hookup sites. The day we were there, there were only two RVs there and I didn’t see anyone to talk to. (There was a phone number prominently displayed to call but I did not). Pit toilet. No shade at all. If you are passing through, it might be good for an overnight stay but other than Carhenge, not much to do in this area. Was suggested that it might be a good stop on the way to Sturgis (tent camping?)
