This is a beautiful loop to hit the highest peak in Massachusetts.

This run takes you up the Bellows Pipe Trail, and back down on the Gould Trail. Both trails are beautifully maintained "Level 1" running culminating in a view from the top of Mount Greylock, the highest peak in MA.


Parking can be found at the end of Gould Road on the right, just before you reach a farm, which is private property. Follow the trail from the back of the parking lot towards Bellows Pipe Trail. The trail is well marked, and all junctions are labeled clearly with signs. Enjoy several views of creeks and a waterfall on your way up the mountain. At about 2,400' (1.75 miles), the trail begins a series of switchbacks, which will leave you up by a portion of the AT. Turn left, and continue running up the gradual ridge climb to the summit.

Once you are done taking in the views at the peak, and have taken enough selfies, follow signs for the Appalachian Trail S, which can be found by the TV antenna at the summit. After about 10 minutes you'll see the signs for the Gould Trail. Follow the clearly marked trail on your way back down the mountain.

After you arrive at the Gould Trail trailhead parking lot there's a small cutout in the wooden fence to your left. There are no signs, but you need to take that path to return to the Bellows Pipe Trail parking lot.

History & Background

Mount Greylock is the highest natural point in Massachusetts at 3,489 feet (1,063 m). Although geologically part of the Taconic Mountains, Mount Greylock is commonly associated with the abutting Berkshire Hills to the east. The mountain is known for its expansive views encompassing five states and the only taiga-boreal forest in the state.

Trail was mostly dry with just a few big muddy sections. A beautiful, though not very runnable, loop and great views from the summit. 8mi
