The campground is wonderful. There were plenty of spaces available during my stay (6/6-6/9), especially the field lots. If you would like a dunes site, get there just before or at checkout. Also, check the winds before setting up a tent (15mph winds added an hour to set up).
The campsite is very dark and quiet after 10p, which makes it very peaceful. Make sure you have a small flashlight ready for the late night run to the restroom, otherwise you may run into one of the grills.
The park ranger I checked in with was very friendly and informative, letting me know all the rules, including the wood fire ban during my stay. You will be asked to choose a few spots before you set up, so I would suggest looking at the map posted in the photos for possible locations.
The village of Ocracoke is two miles from the campground, about seven from the Hatteras ferry. If you forgot or don’t have room to bring your bike, many places in town have bikes for rent by the day, and many told me I could ride and keep the bike out at the campground.
If you are looking for a getaway from everyday chaos, definitely stay on the island and at this campground.
