As part of the NB Trail system, the International Appalachian Trail (IAT) enters New Brunswick at the border of Fort Fairfield, Maine and Perth Andover. It tracks northeast through Mount Carleton Provincial Park and up and over the highest point in the Maritimes. The trail then leads north to Tide Head and crosses into Quebec’s Gaspé Peninsula at Matapédia.

Along the way you’ll see hardwood and softwood tree stands, an abundance of wildflowers, several meandering rivers and a glimpse into New Brunswick’s diverse wildlife population. Hikers have the option of canoeing the final portion of the trail down the Restigouche River. There are 18 bridges along this route that cross the Grog Brook.

The main source of water for the hike will be from nearby rivers. We recommend bringing water filters for the cleanest water.

While there are some campgrounds along the route, many hikers camp on the side of the trail as there’s enough clearance for a tent along most of the trail. Hikers should depend on camping during their adventure as there are no designated IAT shelters.
