The island of Bogue Banks is only 26 miles from one end to the other, but due to the reduced speed limit, you'll need about 45 minutes to travel the entire length. At some points, the island narrows to only a third of a mile wide, giving you excellent views of the ocean and the sound. Mile marker signposts are placed along Highway 58 every half-mile, and these are often used for giving directions.
There is no public transportation on the island, but you can hitch a lift with one of several reliable taxi companies.
