The Farm Service Agency is interested in South Carolina's National Wildlife Refuge because of its diverse array of wildlife and habitats. Visitors to the refuge can expect to see a variety of species, including alligators, bald eagles, and black bears. Specific points of interest include the refuge's three main units: Waccamaw, Cape Romain, and Santee. Each of these units has its own unique features, such as the marshes and creeks of Waccamaw, the beaches and sand dunes of Cape Romain, and the waterfowl and shorebirds of Santee. Interesting facts about the refuge include that it is home to the largest rookery of brown pelicans on the East Coast and that it has been designated as a Globally Important Bird Area. The best time of year to visit the refuge is in the spring and fall, when migratory birds pass through the area.
