My favorite campsites are at Ocracoke Island National Seashore, which are just a sand dune away from the most pristine, uncrowded beaches anywhere on the US eastern seaboard. Separate areas are designated for tent campers, trailers and motorhomes. There are paved pads for RVs but no shade and no hookups. The campground has grills, tables, modern restrooms, unheated showers and potable water. Across the main road from the campground there is a free dump station and a connection to fill water tanks. Campers with a National Park Senior Pass pay half the regular $23/night camping fee. Camping there in September we found great swimming weather and warm water but the crowds and mosquitoes were gone.
