All concrete sites. Outlined sites are back-in and all inner sites are pull-through. The staff couldn't have been nicer. We called 2 hrs out and was told there were plenty of sites and if she wasn't there when we arrived to go to site 84 and settle up tomorrow. I gave no name or payment info! She was still there waiting for us even though we were late. Still gave NO info. Settled next morning with no problems. If we ever get back to the area we will definitely stay here!!! Quite campground even though on busy highway.
