Harbor Island is a man-made peninsula in San Diego Bay in San Diego, California. It was built in 1961 from harbor dredgings.[1] It lies between Shelter Island and Downtown San Diego, directly across Harbor Drive from San Diego Airport. It is 2 miles (3.2 km) long and only a few hundred feet wide. A single road, Harbor Island Drive, runs from one end of Harbor Island to the other and connects it to the mainland.
The "island" includes several marinas which harbor thousands of small sailboats, as well as several restaurants, two high-rise hotels, and Harbor Island Drive Park. It is under the control of the Port of San Diego.
