Intracoastal Waterway

The Intracoastal Waterway is a 3,000-mile (4,800-km) waterway along the Atlantic and Gulf coasts of the United States. Some lengths consist of natural inlets, salt-water rivers, bays, and sounds; others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.
