This is one of my favorite state parks... ever! We stayed 3 nights ($87) for an electric back in site. The site was a concrete pad with a fire pit, picnic table and a little bit of grass that my dog enjoyed. The bathrooms were clean and the campground was nice to walk around. From there, we went to Wind Cave, Jewel Cave, Hot Springs, Mount Rushmore, Sylvan Lake (must see) and took in a play at the Black Hills Playhouse. There's a gift shop, small restaurant, and firewood across the street.
