Marion County is often overlooked by people in favor of the various Red Rock campgrounds that are nearby, but in my opinion, unless you have a boat, there is nothing that puts Red Rock above Marion County. They have done a great job in recent years updating sites a few at a time, adding pavement and full sewer hookups. The campground is well spaced out and it is almost always possible to get a walk up spot on the weekend even if you wait until Friday afternoon/evening. There is only one bath/shower house, but it is centrally located and not far no matter where you are. There are many stores within a 5-10 minute drive if you need supplies, but it still feels isolated while there. The hosts are always great and and on the rare occasion there is an issue, it is quickly resolved. We love going to Marion County and will continue doing so for a long time.
