Teeter's Campground, Ocracoke,NC

Haven't stayed there but I've seen it. Looked basically like a small field beside someone's home. Good location in walking distance of the waterfront, though.

We stayed at the NPS campground which is outside of town and drove in - there was free parking available in town near the the small NPS visitor center but it probably fills up.

Never been there myself. Reviews look mixed. Not much choice out there.
