This photograph features a view of the Saint Augustine Lighthouse from the downtown area looking across the intracoastal waterway. The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Boston, Massachusetts, southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea. Many species of plants and animals can be seen along the path of the ICW.
The ICW enters Florida from Georgia around Mile 715. The northern section of Florida’s ICW tends to be much quieter in general, with many stretches of marshes and wide rivers where there’s typically little traffic. The additional attraction of interesting cities like Jacksonville and historic St. Augustine make this section one of the ICW’s most enjoyable.
The St. Augustine Municipal Marina is located at Mile 778.3 and it ís an ideal base for exploring this charming city. The restored part of the downtown area, the Castillo de San Marcos, the Saint Augustine Lighthouse and Anastasia State Park are among the many highlights. The cruise down to Daytona Beach is typically quiet and interesting with many smaller facilities and attractions. Once in Daytona Beach proper (around Mile 830), there are several marinas to serve as bases directly in the downtown area.
