They have a lot of campgrounds to choose from here and I believe all of them are right along the water. Cabins too. We stayed in the Wind Creek campground since it was the furthest from the main entrance and therefore the most empty. Campsites are along the water among scattered trees. This isn’t too far from Devil’s Tower, an hour or so depending on the route, so you can use this as a backup option when all the sites are full up there. We borrowed a canoe from very kind neighbors but I don’t know if there’s a spot to rent them nearby. If you have a boat, definitely bring it!
