If landscapes are your only desire, you can hardly NOT find a good place to shoot. Ocracoke is certainly a must-visit island. I would also recommend a trip up Hwy. 12 to Pea Island and Oregon Inlet. There is an abandoned life-saving station on Pea Island, just a short walk from pavement. Plenty of wildlife if that takes your fancy.
(Note that the H. Bonner bridge scores a 2 out of 100 for bridges...) crossing over the Bonner Bridge and accessing the beach under the bridge (depending on how much beach is actually there at the time) can yield some wonderful sunset shots juxtaposed with the bridge.
Further up the highway, Jockey's Ridge and the Wright Memorial as previously mentioned. A short trip down Hwy. 64 can lead you out to East Lake, where you'll find Milltail Creek. Perhaps not so much for landscape shots, but LOTS of wildlife (I've traced 1,000lb Black Bear here) and if you're timing is good, civilians can gain access to watch bombing practice on the Army and/or Navy bombing ranges (don't worry, signs give you plenty of warning before you become an unwilling target).
If you head into Manteo, you'll find a replica of the Queen Elizabeth II ship down on the waterfront. I would highly recommend heading down Annanias Dare St. (next to the Baptist Church) and visit Hubby Blivens' wildlife art gallery. Hubby is also a leading historian of the island and can surely lead you to some great locations to visit.
