Harbor Island Beach
You'll wade through warm shallows that stretch thirty yards before the sandbar drops off, while fiddler crabs patrol the cordgrass edge and dolphins surface in the channel. The marsh perfume—pluff mud and spartina—settles over driftwood logs where herons pick through tide pools.

Harbor Island Beach is generally safe for families and swimming, with calm, shallow waters ideal for children. The beach has gentle waves and a gradual slope. However, always supervise children and check tide conditions, as currents can strengthen during tidal changes. Lifeguards are not typically on duty, so swim at your own risk.
