Private and commercial motor vehicles are brought to and from Bois Blanc Island by ferry. There are no paved roads; however, a maintained county road extends from the Island's northeast corner to the far western tip. Fire Tower Road bisects the Island and is also the route used for public access to Twin Lake and Lake Thompson, Bois Blanc's largest inland lakes. There are numerous un-maintained roads and trails.
Plaunt Transportation is the sole provider of ferry services for the Island. Ferries are sailed daily when the straits are not frozen over from Cheboygan to Pointe Aux Pins. The Kristen D is a ferry which operates between Cheboygan and Bois Blanc Island. The ferry can accommodate up to 16 vehicles.
There is a paved public landing field (Airport Code 6Y1, elev. 664').
During some winters, an ice road is marked by cut evergreen trees, allowing travel over the ice between the Island and the mainland. The route generally runs from Pries Landing on the mainland, to Sand Bay on Bois Blanc.
