International Appalachian Trail
<h2>Descriptive IAT Trail Guides:</h2>
IAT Among National Geographic’s Top 20 Trails
Best For: Appalachian Trail thru-hikers looking to beef up their resumes; hikers with a fondness for primordial geology.
Distance: The current trail includes approximately 1,862 trail miles from the end of the U.S. Appalachian Trail in Maine to the North American trail terminus at Crow Head, Newfoundland.
The IAT is an attempt to connect a primordial mountain range that traversed part of the supercontinent of Pangaea more than 200 million years ago before separating into multiple ranges. What remains of those peaks in North America has become the famed Appalachian Mountains of the United States, but few of the Appalachian Trail’s thru-hikers will want to admit that the mountains continue on into Canada—and don’t stop there. The remains of those mountains stretch from Labrador to Greenland and then down to the European continent, with vestiges in Scotland, France, Spain, and even across Gibraltar to Morocco.
