Mott Island Trail is a 2.3-mile loop around the shore of the island that holds Isle Royale’s summer headquarters. It follows the protected Rock Harbor shoreline over gentle rises and dips; the eastern end is the standout stretch. Allow about 1.5 hours on foot, before adding time for boat access.
The connected mapped paths make a 2.3-mile outer loop. Published directions give 2.6 miles for the full circuit and mention a 1.8-mile crossover, but those figures do not match the available connected paths. Treat the distance as approximate and check local wayfinding before choosing a line.
