What is

The Great Loop?

The Great Loop is a continuous epic journey that consists of ­­­travel along the Canadian Heritage Canals, Great Lakes, inland rivers of America’s heartland, Gulf Intracoastal Waterways, and the Atlantic.  There are several loop entrances and exits as well as numerous places to explore along the way, so no two trips are ever quite the same. An official ‘Looper’ is any recreational mariner who completes the journey. If you are interested in more information, visit America’s Great Loop Cruisers’ Association for an Interactive Great Loop Map, Great Loop Radio, webinars, and Member events.
