About our partner
International Appalachian Trail/Sentier International des Appalaches Council
The Council of the International Appalachian Trail was launched in June 1994 when representatives from Maine, New Brunswick and Quebec gathered to begin the work of completing 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, which 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 that 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, and all 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.
