There is a new CG that opened a year or two ago called Frisco Woods. There isn't much of a beach there but it is beautiful and on the shore.
Anything south of that and you are going to take the ferry to Ocracoke Island, which personally I recommend. It's about an hour ferry ride and it is no cost. There is a private CG and a NPS campground on Ocracoke. Very nice. A very short walk on the path between the dunes and you are on a fairly secluded beach with very few people and you don't have to deal with the New Englanders (I kid) and congestion. There's some nice restaurants and places to visit in the village.
