Overview

There is no single route or itinerary to complete the loop. To avoid winter ice and summer hurricanes, boaters generally traverse the Great Lakes and Canadian waterways in summer, travel down the Mississippi or the Tennessee–Tombigbee Waterway in fall, cross the Gulf of Mexico and Florida in the winter, and travel up the Atlantic Intracoastal Waterway in the spring. Depending on speed of travel, the route can take as little as two months, but more typically it takes about a year to complete the trip. The route may also be completed in segments. The current record time for completing the great loop is 19 days, 19 hours, and 50 minutes. This run took place between June 15 and July 6, 2024, and was completed by Scott Flowers, Mike Bailey, and Scott Swerdfeger. Loopers can begin at any point along the route, and when they return to their starting point, they are said to have "crossed their wake" and to have finished the Great Loop.

The America's Great Loop Cruisers' Association (AGLCA) assists Great Loop cruisers by sharing safety and navigational and cruising information, while providing a networking platform for Loopers through its members-only discussion forum. Boaters can exchange information about topics such as marinas, locking through, water depth, hazards, repairs, fuel prices or dinner reservations and sight seeing. The AGLCA also hosts twice-yearly gatherings for Loopers currently on the Loop and those planning a Great Loop trip.
