The trail has been primarily a backcountry footpath for over 150 years. Two sections of the 117-trail are designated NRTs.
The first section is approximately 23 miles and runs along the Mt. Holyoke Range and through Hampden and Hampshire counties. Due to unique geologic formations, this segment takes visitors through a forest environment not usually found in central New England. Its natural and cultural resources include the legendary "Horse Caves," hiding place used during Shay's Rebellion.
The second section runs approximately 30 miles and crosses Franklin and Worcester counties. This segment allows for natural and human history interpretation in a wild and remote terrain. Some trail segments in section 2 permit snowmobiles, mountain bikes, and equestrian users. Volunteers affiliated with the Berkshire Chapter of the Appalachian Mountain Club (BCAMC) maintain the trail. Detailed route descriptions of the trail are at www.amcberkshire.org/mmtrail
