We were driving through and wanted to see Rushmore and were trying to book whatever we could find. Just so happened Rushmore KOA had a site available.
KOA's for me are a place to park for the night and get going the next morning on a long trip when trying to make good time. But wow...Rushmore KOA is incredible. I call it "Disneyland of South Dakota". So many attractions, sports, games, fishing, fun rentals, and things to do with a billion other kids and families. Excitement everywhere...and very very busy!
We are childless and weren't quite expecting what the park was going to be. Definitely not our bag, but I realize that is specific to us as a childless couple! lol. But I think it would be awesome for families - judging clearly by the number of families there having fun!
The staff were wonderful, and the park was in order. Decent accommodations, but with a little less privacy and space than we'd prefer. Full hookups. We also booked last minute and didn't have any choice in sites. YMMV!
