Pea Island National Wildlife Refuge
Heading south from Nags Head, Pea Island's miles of undeveloped coastline kick off one of the East Coast's most scenic drives. The refuge consists of 5,834 acres of marsh on the Atlantic Flyway, plus 25,700 acres of refuge waters. To the delight of birders, more than 370 species have been sighted from its observation platforms and spotting scopes and by visitors who venture into the refuge. Pea Island is home to threatened peregrine falcons, piping plovers, and tundra swans, which winter here, and to 25 species of mammals, 24 species of reptiles, and 5 species of amphibians. A visitor center has maps of trails that lead through the salt marsh and around ponds. On the west side of the highway are 13 miles of pristine beach.
Remember to bring bug spray if you go for a hike, especially in spring. Also, there's no tree coverage on trails, so plan peak-summer walks early and late in the day.
