In addition, the United States has a large coastline along the Great Lakes which it shares with Canada. There are also many large US Rivers and other US Inland Lakes which are travelled by cruising vessels throughout the country. The Atlantic and Southern coastline also has a protected passage, the Intracoastal Waterway, which reaches from New England all the way to the southern tip of Florida and then continues on along the coastline of the Gulf of Mexico through the Southern States until ending at the Texas/Mexico border.
There are many large US Bays and Sounds as well, which are heavily populated with cruising vessels.
