Appalachian Trail

Appalachian Trail: 100-Mile Wilderness

Explore the Appalachian Trail's wildest stretch.

“The name alone has such a wild, inspiring, and inviting feel,” says Scott Adams, a member of Backpacker’s regional panel. “And the fact that we East Coasters have a substantial chunk of rugged, uncrossed trail is amazing. We should all see that as an invitation.” The extra-burly route stretches from ME 15 in Monson to Abol Bridge in Baxter State Park.

Go from south to north and tack on a 14-mile climb of 5,268-foot Katahdin, Maine’s highest point. On the route, you’ll pass through tunnels of tight pines hiding moose, mirror-calm ponds, berry bogs, rushing streams, and craggy ridges with stay-awhile views. Go in late summer to avoid bugs and enjoy tales from thru-hikers. Allow nine to 12 days.

Waypoints

HUN001

Location: 45.331215, -69.535934

AT continues straight across ME 15. To access Monson, ME (the last major town on the AT that LOVES hikers), turn R for 4-mile jaunt into town. This small and friendly town is often packed with hikers, as it serves as the last major town for Northbound thru-hikers before Katahdin and 100-Mile Wilderness. Monson has a sign in the center of town indicating distances to Springer/Katahdin.
