FATMAP difficulty grade
The Hundred Mile Wilderness on the Appalachian Trail is one of the most challenging and rugged backcountry stretches of singletrack you can find in New England.
According to [this source](https://fastestknowntime.com/route/hundred-mile-wilderness-me), it's "generally considered the wildest section of the Appalachian Trail, and one of the most challenging to navigate and traverse," despite its status as a National Recreation Trail.
Endless summits and backcountry waterways define the landscape, and remote logging roads are about the only way to gain access to the route other than its start and finish. For trail runners eyeing this section of the AT for a long adventure run, its difficulty cannot be understated.
According to [FastestKnownTime.com](https://fastestknowntime.com/route/hundred-mile-wilderness-me), elite runners have clocked times around 30-hours, while others could range anywhere from 40 to 60 hours.
As such, distance trail runners, thru-hikers, and fast-packers frequent the trail during the warmer months. The *official* Hundred-Mile Wilderness begins at Abol Bridge and extends to the entrance of Baxter State Park.
A visit to the AT's northern terminus at Mount Katahdin is often paired with this run, but make sure to call the state park first for the most up-to-date information on trails and operating hours.
Those simply visiting the area will likely want to check out [this route](https://fatmap.com/routeid/129922/mount-katahdin-via-the-abol-trail) to the summit of Katahdin during their visit.
For runners and hikers alike, there are virtually no crew access points for the entire stretch, though [this source](https://en.wikipedia.org/wiki/Hundred-Mile_Wilderness) notes how "in 2000, a series of new logging roads and a marked side-trail offered hikers re-supply and lodging opportunities between miles 55 and 65 heading northbound from Monson." Between ridgelines, water can be treated or filtered from most of the ponds and lakes, though always be mindful of any active logging activities that may be happening in the vicinity.
