Barrier Island's Location
Barriers Island can be found along approximately 13 percent of the world's coastline.
A barrier islands in a long, thin sandy stretch of land, oriented parallel to the mainland coast that protects the coast from full force of powerful storm waves. Between the island and the mainland is a calm, protected water body such as a lagoon or bay. Barrier islands are small clusters of islands that exist off the coast of a land mass.
