We spent 3 nights beach camping in our VW Vanagon, and highly recommend this destination if you have the means! The ferry is $135+ for vehicles, plus $20 per person roundtrip. The beach driving permit is $75 unless you buy it by March (I think). We lucked out with our dates just preceding a big fishing competition, and there was a LOT of open beach space. Almost everyone is there to fish. We took bikes and enjoyed cycling around at low tide. Be sure to camp above the high tide zone, which is black sand. There are narrow/impassable points on the beach at high tide, but there are ramps to the back road every mile. Some ramps are very deep sand, others flat and packed. We got by without 4wd, but we didn’t explore beyond finding a spot not too far from the ferry drop off. We befriended our neighbors who took us to the lighthouse at the southern end of the island, which was beautiful! Currently closed for renovations, and the lightkeeper’s house was closed due to the government shutdown. Overall, south core banks is absolutely worth the effort!
