Mahoosuc Notch is a deep gap in the Mahoosuc Range of western Maine in the United States. It is traversed by the Appalachian Trail.
The boulders on this mile-long section of trail present obstacles that must be climbed over and sometimes under, creating a unique hiking experience. There are occasional 10feet drops, and places where packs must be removed to squeeze beneath a boulder.
Many hikers call this stretch one of the slowest on the approximately 2200adj=onNaNadj=on trail. This so-called "killer mile" or the "Toughest Mile"[1] is a very tough section that can cause even the most experienced hikers to slow down.[2]
