I stayed at Paugus Bay Campground years ago and they always have campsites for sale. Be warned though the campers that are on the sites are not pretty, but it gets you in the door. The other thing there is the boats cannot be bigger than 18', I think because you need to go under the railroad bridge. I have a friend that was there for 12 years and another that just took over his parents site. It is a little hilly depending on where your site is. Its right outside of Wier's Beach.
