I would recommend getting a reservation before showing up. They have laminated signs posted on the campsites to let you know which ones are taken. When I showed up I found site 13 open for only one night. In the morning I was told by the DNR that most weekends are booked solid, but half the sites are empty and people don't cancel the reservation; so they can't legally rent them out. Many sites are large enough to pull a camper thru. No hookups but that wasn't an issue for me.
