The AYE route is inspiringly spectacular. It travels through the heart of six US National Parks (including the Park Service's three largest -- Wrangell-St. Elias, Denali, and Gates of the Arctic) and two Canadian parks. It crosses only eight major roads and once goes 615 miles through completely undeveloped wilderness (no villages, no roads, no pipelines, etc.). It features lengthy traverses of the Alaska Range (home of Mount McKinley) as well as the Brooks Range, arguably the greatest wilderness in the world. It includes long floats on some of North America's wildest rivers, including the Copper, Yukon, Peel, and Kobuk. And it follows two historic routes, the Iditarod Trail and Chilkoot Trail.
Only 10 percent of the AYE route follows manmade throughways like hiking trails, ATV tracks, and vehicle-accessible roads; and about 15 percent of the route follows winter dogsled and snowmobile routes. The bulk of AYE route is organic: there are 1,850 miles of off-trail trekking, 350 miles of off-track skiing, and 1,350 miles on rivers and saltwater bays.
