The International Appalachian Trail (IAT; , SIA) was originally a hiking trail which ran from Katahdin Woods and Waters National Monument, in Maine, through New Brunswick, to the Gaspé Peninsula of Quebec, after which it followed a ferry route to Newfoundland, and then continued to the northern-easternmost point of the Appalachian Mountains at Belle Isle, Newfoundland and Labrador. As of July 2020, there are widely geographically dispersed IAT-branded walking trails in Greenland, Iceland, Norway, Sweden, Denmark, Scotland, Northern Ireland, Ireland, Isle of Man, Wales, England, Spain, Portugal, and Morocco. History The IAT was proposed in 1994 by Richard Anderson, a Maine fisheries biologist, with plans to traverse the portions of the Appalachian Mountains in Maine, New Brunswick, and Quebec that the Appalachian Trail did not cover. Following route selection, construction of the trail took place through the late 1990s. The first person to thruhike the IAT, as it then existed, was John Brinda from Washington State, in 1997. He did this as part of a long-distance hike of what is known as the Eastern Continental Trail starting in Key West, Florida ending at Cap Gaspé in Quebec. He was the first person to thruhike the entire Eastern Continental Trail. The Newfoundland and Labrador extension to the IAT was proposed in 2003 and is still under construction. When completed, it will add an additional 1,200 km of trail. The official opening of the first trail section of the IAT Newfoundland was September 23, 2006. In 2009, IAT officials met with the British Geological Survey in Scotland to discuss whether to extend the IAT to the Appalachian terrains of Scotland, Ireland, Northern Ireland, and Wales, setting off a series of expansions through Europe and Northern Africa in which existing trails co-branded with the IAT. Route The IAT/SIA starts in Katahdin Woods & Waters National Monument in the U.S. State of Maine. Thence to Mars Hill, Maine, before following the U.S.-Canada border north to Fort Fairfield, Maine, where it crosses the border into Perth-Andover, New Brunswick. It continues up the Tobique River valley to Mount Carleton before crossing the Miramichi Highlands to the Restigouche River valley in Quebec and along the Chic-Choc Mountains of the Gaspé Peninsula, ending at the peninsula's easternmost point, Cap Gaspé in Forillon National Park. From Cap Gaspé, the IAT skips to a small section in Prince Edward Island, Nova Scotia, and over the Gulf of St. Lawrence to
