The Maine section of the IAT/SIA is about 138mi/222km long and begins on the Katahdin Loop in the Katahdin Woods & Waters National Monument east of Baxter State Park. The trail generally follows the East Branch of the Penobscot River north through the Monument, before turning east towards Mount Chase and, eventually, Houlton. Just before Houlton, the trail turns north again and continues to and across Mars Hill Mountain in Aroostook County. It then follows the United States/Canadian international border northward to Fort Fairfield where it crosses into Perth-Andover, New Brunswick.



The New Brunswick section of the IAT/SIA is about 185mi/298km long and begins at the United States/Canadian international border in Perth-Andover. The trail then accompanies the Tobique River through the village of Plaster Rock to Nictau. The trail then continues northeast to Mount Carleton Provincial Park before heading west to St. Quentin and Kedgewick. It then turns northeast again crossing the Upsalquitch River and then the mouth of the Restigouche River at Tide Head, NB.

About our partner

International Appalachian Trail/Sentier International des Appalaches Council


The Council of the International Appalachian Trail was launched in June 1994. Representatives from Maine, New Brunswick and Quebec gathered to begin the work. The goal was to complete a footpath to connect the three highest points of land in each jurisdiction. Now, 22 chapters in 13 countries on 3 continents around the arc of the North Atlantic Ocean Basin continue the work. Chapters take on the responsibility of building and maintaining the footpath. The trail traces the ancient Appalachian/Caledonian mountain chain from North America to North Africa. The Council is an informal association whose members agree to a set of structures and responsibilities. These responsibilities includes establishment and maintenance of the footpath, the creation of maps, guides, and other promotional materials. Chapters are encouraged to develop their own means of public communication and education. All of the chapters contribute stories and other promotional material to the shared web portal.

Atlas Guides works with the IAT/SIA to create and maintain the International Appalachian Trail/Sentier International des Appalaches Council’s smartphone navigation app.
