In the 1930s, the island was developed into a state park by the Civilian Conservation Corps as bridges were constructed to connect the outer Sea Islands with Beaufort. Thanks to limited human development, the island remains a preserve for its abundant wildlife. There are more than of beach, a dense maritime forest in the interior areas, and an extensive saltwater marsh on the western side. The most notable attraction is the 19th-century lighthouse, listed on the National Register of Historic Places. While not operational, the lighthouse tower features a rotating light in the tower that is turned on at night.
