This refuge is made up of 5,834 acres of marsh on the Atlantic Flyway. To bird watchers' delight, more than 365 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. A visitor center on Route 12 has an information display and maps of the two trails. Remember to douse yourself in bug spray, especially
in spring. Guided canoe tours are available for a fee.
