Erbie Campground is a nice but quaint site. It is located right on the Buffalo River and has a couple table/benches to eat meals at. The plot of grass to camp on is not well maintained and had grown pretty high when I was there. It does offer a nice place to go swimming however if you are there during the summer. There is a single gender neutral bathroom that was well kept and a pay phone available. It is definitely on the smaller side so I would make sure there is space available (by calling the rangers office) before driving too it.
