Appalachian Trail on Mount Greylock
The Appalachian Trail crosses the summit of Mount Greylock, the highest point on the AT in Massachusetts at 3,491 feet. 11.5 miles of the trail run through Mount Greylock State Reservation, part of the 90 miles DCR counts in Massachusetts. Look for white blazes. An AT climb to the summit from Notch Road is 3.2 miles from Wilbur's Clearing on Notch Road.
Day hikers use the AT for most summit routes. Thru-hikers and section hikers walk the whole ridge, past Bascom Lodge on top.
