Trail Guides & Maps

The Maine section of the IAT/SIA is 138 miles (222 kms.) long.


PLEASE NOTE:  The Katahdin Lake east entrance to Baxter State Park (KLE) is closed.  The Maine Chapter of the International Appalachian Trail (MCIAT) is currently working with Baxter State Park and other landowners to establish a starting point for the trail nearer the southern entrance of the park. This new trail section will increase trail mileage and will appear on updated maps and in an updated trail description. MCIAT hopes to have this route completed by May 2017.


The route passes through boreal forests, follows trails, old logging roads, rural public roads, an abandoned railroad bed, to the potato fields of Aroostook County and the cleared strip of land along the boundary between the United States and Canada. Beyond Fort Fairfield, the trail enters the province of New Brunswick.


Reservations for camping/lodging are required in Baxter State Park and in the parks of Canada for camping/lodging.
