Beach Description

Lighthouse Island
South Carolina DNR Sea Turtle Conservation Program

Cape Romain National Wildlife Refuge has four islands with ocean facing beaches: Bull, Cape, Lighthouse and Raccoon Key. The western arm of the Cape Beach often merges with Lighthouse island. Cape is 9 km long when not joined to the 4.5 km beach of Lighthouse Island. Cape, Lighthouse, Bull and Raccoon Key have highly erosional beaches with low elevations. However, since there is no beachfront development on these islands. Turtles are able to place their nests in the dunes behind the erosional areas. Cape Island is the most significant loggerhead nesting beach north of Cape Canaveral with an average 1,000 nests per season. The beach is steep with coarse sand. Long sections of the beach consist of flat, washovers and the nesting turtles tend to wander extensively in these areas. Lighthouse averages 200 nests per season.
