The refuge lies within the Atlantic Coastal Plain province of South Carolina.
One of the features of the refuge is Dingle Pond, which is a Carolina Bay.
The refuge was established in 1941. The refuge was formerly much larger, but was reduced greatly in size in 1976 when the Lake Moultrie section in Berkeley County was discontinued due to lease termination.[1]
The refuge consists of four units, Bluff with the Visitor Center, Pine Island, Dingle Pond with a Carolina Bay, and Cuddo the largest unit. The visitor center is open Tuesday through Friday, 8am to 4pm, but may be closed due to volunteer availability. Call ahead to be certain. The Cuddo unit is closed on Mondays.
