Stayed near there at a place called "Tuck in the Wood" campground. I recall that it was full hookup and little more than that. As I recall it was convenient to Beaufort, but it has been some time.
Not far from there I recall a state campground, I think Hunting Island, was next to ocean, sort of remote, difficult to get in during summer months, and don't think it is full hookup.
Hope it helps, has been a while since there.
