Our initially reserved campground nearby was sketchy, so we called KOA Deadwood at 4:30 hoping for a last minute reservation (even though the app said they were full). Dana, the host, set us up with their last available site and was super kind allowing us to pay upon arrival since our cell phone signal was bad. We were immediately impressed by the grounds which included a trolley to downtown Deadwood, a wandering donkey, and the cleanest private bathrooms. Would highly recommend anyone looking to stay in the Black Hills area stay here!
