The Norwalk Islands are a chain of more than 25 islands amid partly submerged boulders, reefs and mudflats along a six-mile (10 km) stretch and mostly about a mile off the coast of Norwalk, Connecticut, and southwest Westport, Connecticut, in Long Island Sound. Various laws protect the islands, including town ordinances, the Coastal Barrier Resources Act, the National Wildlife Refuge System Administration Act of 1966, and the Endangered Species Act. On a clear day, Manhattan's skyscrapers are visible.
