Camping on Ocracoke for their April 5k / 10k race has been my camping season opener for several years. The Beachcomber is a good campground at the north end of the village conveniently situated behind the gas station and near the grocery/hardware/liquor store. Park your car, set up the camp site (19 and 20 are the best tent sites) and unload the bike. Everything on the island is walk/bike distance.
The owners have been doing a good job with this campground since they bought in a few years ago. Each year there are improvements. And Ocracoke is just a special place.
I'll remind myself to take some pictures this year and update this post.
