The East Branch Section of the IAT in Maine begins at the
Katahdin Lake East Access trail head at Baxter State
Park and runs to the Grand Lake Road near the outlet of
Matagamon Lake. The section is approximately 30 miles
long and parallels the East Branch of the Penobscot River
for much of its length.

should know before undertaking their hike, including a
feature-by-feature mileage guide, information on local

The Maine Chapter of the International Appalachian Trail (IAT) was incorporated in 1994 to promote the establishment of a long-distance hiking trail from the eastern boundary of Baxter State Park, where Mt Katahdin is the northern terminus of the Appalachian Trail, to the northern end of the Appalachians in North America. The long-term IAT goal is to locate sections of the trail on all the terranes of the original Appalachians. In addition to the Maine Chapter, the IAT has other North American chapters responsible for the trail in New Brunswick, Quebec (referred to as the SIA, Sentier International des Appalaches), Nova Scotia, Prince Edward Island, Newfoundland and Labrador, and Greenland. European IAT chapters have now been established in Ireland, Scotland, England, Wales, Iceland, the Faroe Islands, Norway, Sweden, Denmark, the Netherlands, Spain, and France.
