I really like it over in the Moorhead City/Atlantic City area. There's a terrific fort over there (Macon?) that's fully restored and accessible. You can also wander along the barrier islands rimming the sound, ranging all the way from Cape Hatteras down to Ocracoke and taking in the Pea Island National Wildlife Refuge and Cape Hatteras National Seashore along the way. Lots of lighthouses and terrific coastal landscapes as you go. And best of all for me is the Wright Brothers National Memorial at Kittiwake. That in particular lends itself to early morning shooting.
It's a couple of hours or so from Raleigh over to the coast, but well worth every second of the drive and any extra nights you can manage once you are there.
