Welcome to


The A.T. in Maine is wild, spectacularly scenic, challenging and ultimately fulfilling. Maine’s tallest mountain, Katahdin, is typically the beginning or the satisfying end of a thru-hike, a journey by foot of all 2,190+ miles of the A.T. that is undertaken by thousands each year.

Cool to know

Maine is the A.T.’s most challenging, rugged and remote state, and it has the wildest feel of any area of the Trail. Maine offers some exciting features that are uncommon elsewhere on the A.T., including wildlife like moose and loons and pristine lakes. It’s also famous for hosting the hardest mile of the Trail: Mahoosuc Notch. 



Need to know

Maine is famous for its unbridged stream crossings, which can be hazardous after spring snowmelt and heavy rains. The Kennebec River, the widest unbridged crossing, has a free ferry service in the form of a canoe during hiking season. This is the A.T.’s official and historic route; fording the river is extremely dangerous because the water level can rise rapidly and without warning.

A.T. Long Distance Hiker Permit—Baxter State Park

A free A.T. long distance hiker permit is required of all long-distance A.T. hikers: Northbound Thru-Hikers (Nobos), Southbound Thru-Hikers (Sobos), Flip-Flop Thru-Hikers and Section-hikers.

Long distance A.T. hikers must obtain a permit card in person at the Katahdin Stream Ranger Station before climbing the Hunt Trail (the A.T. route up Katahdin).

The number of AT-Hiker Permit Cards are limited to an annual Baxter State Park quota: 3150 A.T. hikers. If all available permit cards have been issued, “The Birches” long distance hiker campsite will close for the year. Hikers may complete their hike by obtaining a Day Use Parking Reservation (DUPR) or campground reservation. [Note: A hiker’s initial entry into Baxter will be on foot from Abol Bridge, not through Togue Pond Gate, even if “The Birches” is closed.]
