Sea Islands, Barrier island chain near Charleston, United States.
The Sea Islands form a chain of low sandy islands stretching along the coasts of South Carolina, Georgia, and Florida for nearly 300 miles (480 kilometers). Most of the islands are surrounded by salt marshes, tidal creeks, and maritime forests, with some connected to the mainland by causeways.
The islands were settled from the early 18th century and became centers for cotton and rice cultivation on large plantations. After the American Civil War, many formerly enslaved people remained and formed communities that preserved their own traditions.
These islands preserve the Gullah Geechee language and way of life, which blends African and Creole influences with local traditions. Artisan work such as sweetgrass basket weaving and spirituals in community chapels show this living cultural heritage.
Many of the islands are accessible by bridges and causeways, while others require a ferry or boat. Several state parks and nature reserves offer trails, beaches, and visitor centers.
The islands enjoy an unusually long growing season of around 290 days per year due to the influence of the Gulf Stream. These conditions favor plants such as ancient live oaks, palmettos, and sprawling maritime forests.
