The IAT began in 1995 with the goal of creating a walking trail that followed the Appalachian Mountains from Mount Katahdin, Maine to Cap Gaspe, Quebec. Since then the IAT has grown to over 5000mi/8000km in length and include trails in 13 countries on 3 continents around the North Atlantic.This bundle includes five sections of the trail: Maine, New Brunswick, Quebec, Prince Edward Island, and Nova Scotia.



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. The trails turns west here, and crosses the Restigouche into Quebec at Flatlands, New Brunswick.



The Québec section of the IAT/SIA is about 401mi/645km long and begins in Matapédia at the bridge crossing the Restigouche River and then runs northwest to Amqui, south of Lac Matapédia. Here, the trail heads northeast through the Reserve Faunique de Matane and then on to Mount Logan in the western portion of the Parc de la Gaspésie. The trail then turns eastward, continuing across Mont Albert and Mont Jacques Cartier and finally along the legendary cliffs of Cap Gaspé in Forillon National Park, where it ends at Shiphead.



The Prince Edward Island section of the IAT/SIA is about 150km /90mi long and begins in Borden-Carleton near the intersection of Trans-Canada Highway and Dickie Road. However, many hikers start their hike at the historic lighthouse in the Marine Rail Park adjacent other Confederation Bridge.

From Borden the IAT follows the Confederation Trail northeast to Emerald Junction before turning east, heading to Mount Stewart. Shortly after passing Mount Stewart the IAT leaves the Confederation Trail and heads south, following a series of trails and road walks to the Northumberland Ferry Terminal in Wood Islands. From here, a hiker can catch a ferry to continue the IAT in Nova Scotia.



The Nova Scotia section of the IAT is about 490km/300mi long and begins at the Northumberland Ferry Terminal in Caribou. The trail starts with a 12km road walk to Pictou, where it picks up the Trans Canada Trail which it follows for another 12 or so km. After that, the trail follows a series of small roads mostly along the Northumberland coast until it reaches the Canso Causeway and Cape Breton Island.

On Cape Breton, the IAT/SIA follows the multiuse Celtic Shores Coastal Trail nearly to Inverness, before turning southeast and following a series of logging roads through the low mountains in the centre of the island to the shores of Bras d’ Or Lake. The trail then turns northeast and follows roads along the shore of St. Andrews Channel to North Sydney where NoBo hikers can catch a ferry to Newfoundland.

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.
