So many choices!! We are from SD and have camped in the "Hills" since we were kids. Rafter Bar J has been there since I was a kid and stayed there then.
It is nice place as everyone has mentioned but we also like to check out other places. Stayed at Horse Thief which is close to RBJ and liked it there also. Since we were on bikes, spent little time at CG and more time riding.
There are very nice State Parks that are a lot less in cost. Sheridan Lake, Pactolla, and others have some Parks on or near lakes and offer a more secluded camping. There are some others that are in NPS and have no facilities but really seculded areas with trout streams running through them. I was at one last year and it was large enough for 5ers to get in. There was water in few places to draw from. No dumping stations.
Go to the SD home page, they have a very good tourism division that can get you more information.
There are some newer CG's that I want to also check out sometime we found last year. We're going back in June. Have a great time!!
