The Metacomet-Monadnock Trail is maintained by volunteer efforts largely facilitated by the Berkshire Chapter of the Appalachian Mountain Club. Many groups are invested in preserving the pathway and viewshed of the Metacomet-Monadnock Trail, including The Trustees of Reservations, Mount Grace Land Conservation Trust, Friends of the Mt. Holyoke Range, the Society for the Protection of New Hampshire Forests, the Amherst Conservation Commission, the State of New Hampshire, and the Commonwealth of Massachusetts.
