🏆 100-Mile Wilderness AT — 43,000-acre wilderness unit on the Appalachian Trail’s legendary 100-Mile Wilderness
Nahmakanta Public Reserved Land covers 43,000 acres in the heart of the Appalachian Trail’s legendary 100-Mile Wilderness — the final (or first) section of the 2,190-mile trail, with no roads, towns, or services. Nahmakanta Lake is a pristine mountain lake where the AT passes along the shore. The 100-Mile Wilderness is considered the wildest, most remote section of the entire Appalachian Trail — thru-hikers must carry 7–10 days of food to traverse it. “Nahmakanta” is Abenaki for “lake of the largest fish.”

Frequently Asked Questions
What is the 100-Mile Wilderness?
The 100-Mile Wilderness stretches from Abol Bridge to Monson — the longest section of the AT without road crossings. Thru-hikers carry a week or more of food. Despite the name, it’s closer to 95 miles — but feels like 200.
What is the 100-Mile Wilderness?
The 100-Mile Wilderness stretches from Monson to Baxter State Park — the Appalachian Trail’s most remote section. No paved roads, no towns, no cell service. Hikers must be completely self-sufficient. The terrain includes mountains, bogs, lake shores, and dense spruce forest. For northbound thru-hikers, it’s the final challenge before summiting Katahdin — the AT’s northern terminus and emotional climax.
Make it a road trip: Pair a visit with Baxter State Park (within about an hour’s drive) or Wassataquoik (within about an hour’s drive).
