We stopped here for one night in our fifth wheel when driving home from Mt. Rushmore. The spots are big, with plenty of distance from your neighbors. The campground looked clean and well tended. Unfortunately it stormed all night the night we were there, so we were not able to enjoy the park or walk around. Mosquitoes were horrible when we did go out at all. It is easy to get to off of I-35, so that was a plus. My biggest complaint is the cost. It was $26 dollars for the site, which was electric only. That was not bad, but they charged $7 fee to book online, then charged a five dollar fee for a parking pass (did not know about the parking fee until we arrived). So a total of $38 for an electric only spot? If you are just passing through the area for one night you might as well pay a little extra elsewhere for full hook-ups.
