The Norwalk River enters Long Island Sound at Veteran’s Park in South Norwalk, 40 miles northeast of Manhattan. At the river’s mouth is a tidal estuary and harbor used by hundreds of pleasure and fishing boats. Marine life is abundant, and oyster fishing has been an important activity going back to pre-colonial times.
Educational tours of the harbor are offered by the Maritime Aquarium, and an annual Oyster Festival is sponsored by the Norwalk Seaport Association. One mile offshore is a chain of islands which serve as a wildlife refuge and, in specific areas, as a popular destination for boaters. One particular attraction is the historic Sheffield lighthouse.
