At the northern end of Hatteras Island, and named after the dune peas that grow in the sand, this 5834-acre (land portion only) reserve is a bird-watcher's heaven, with two nature trails (both are fully accessible to people with disabilities) and 13 miles of unspoiled beach for the 365 recorded species here. Viewer scopes inside the visitor center overlook an adjacent pond. Check the online calendar for details about guided bird walks, turtle talks and canoe tours.
