The International Appalachian Trail runs through Maine, New Brunswick, Quebec, Prince Edward Island, Nova Scotia and Newfoundland and Labrador. In Western Newfoundland the trail route extends from Port-aux-Basques in the south, through Gros Morne National Park, to Crow Head (just east of L'Anse aux Meadows) at the tip of the Great Northern Peninsula.

The Newfoundland and Labrador Chapter of the SIA/IAT was formed at a general meeting held in Corner Brook on July 4, 2003. The goal of the Chapter is to extend the SIA/IAT an additional 1,200 km along the Long Range Mountains from Port aux Basques in southwestern Newfoundland to Crow Head (just east of L'Anse aux Meadows) at the northern tip of the Great Northern Peninsula.
