Small (20 sites) primitive campground located only one mile from Keystone SD. Great for seeing Mt Rushmore, Crazy Horse Site and Custer State Park. Mostly tents as large RVs and trailers have difficulty with tight curves. Some sites small but we reserved #19, it is very large and offers best privacy. Well maintained vault toilets and potable water available. Quiet at night but some road noise and helicopter traffic during the day. Friendly hosts.
