We've never stayed here and I'm always hesitant to endorse or knock any campground because we all have different criteria for determining the ideal campsite. From the road however, this place looks like an open lot with tents pitched in a somewhat haphazard fashion. It appears to be geared more towards the younger crowd coming down to surf, kite, sail and party - EXACTLY the type of place that I'd have chosen forty years ago!
Although we wouldn't stay here, we also avoid Camp Hatteras and the KOA which are the two 'resort' campgrounds (and priced accordingly) on the OBX. Most folks seem to think Ocean Waves is the best value for the money in that area but we don't stay there either. Our choice would be one of the NPS campgounds - Frisco, Ocracoke, Oregon Inlet and Cape Point in that order. These, especially Frisco, are less crowded and offer larger and more private sites than the commercial campgrounds. There are no hookups however and the showers are cold water only so these certainly aren't for everyone either.
We'll be at Frisco October 6-8 which is the last weekend they're open so we probably couldn't make it again for the dates you're planning. If you can come a week earlier and can live with a 'rustic' setting, Frisco is $20/night. In any event, I hope you and all others
who might attend have a great time where ever you stay. Since this is sort of in our backyard, I'll be glad to try to answer any questions. Fall
is a great time to visit the OBX.
