Tucked between St. Helena Island and Hunting Island, Harbor Island is a 1,400-acre private community on the Harbor River. A small group of people call the island home year-round. Others enjoy it as a quiet and secluded vacation spot. A peaceful, gated community, Harbor Island features a variety of vacation rental homes and condominiums to accommodate couples, families or large groups. Three outdoor pools, tennis courts, a putting green, and three miles of pure, untamed, sandy white beach create a private vacation playground unlike any other.
