The Great Loop is a continuous waterway that recreational mariners can travel that includes part of the Atlantic, Gulf Intracoastal Waterways, the Great Lakes, Canadian Heritage Canals, and the inland rivers of America's heartland. Anyone who completes the journey is then named an official 'Looper.'
For a safe and enjoyable trip, there are a few things to consider when traveling the Great Loop—a great amount of time, a boat with less than a five foot draft to travel inland waterways, NOAA nautical charts, and a NOAA radio. Along the way, it is possible to visit a number of national marine sanctuaries and estuarine research reserves.
