The campground we went into was pretty big, like it has 2 sepeate areas of campsites, one is right when you come into the campground and if you keep going then there is another set of campsites. From what I can remember I think some campsites were pretty hilly.
There is also another campground right around there, we didn't drive through it but I saw there website, it is just like an open field. But they have portable corrals that you can use, so I think im going to be going to that one. Here is the link: index
How far away are you from there? Im only about 45 min. Away!
