Monadnock-Metacomet M&M Trail

Monadnock–Metacomet M&M Trail is a hard, long-distance hiking route on the Metacomet Ridge and beyond, built as the Massachusetts and New Hampshire extension of the Metacomet Trail system. The corridor runs between the Connecticut/MA state line and the summit of Mount Monadnock in southern New Hampshire, totaling about 114 miles (183 km).

Plan for a mix of trap-rock ridges and upland terrain that trends from cliff-and-ledge country into more rural, wooded plateau edges as you head north. The mapped character includes exposed, steep stretches tied to the Metacomet Ridge ranges, then shifts toward an upland plateau with sparse viewpoints and a few bare summit tops.

A full northbound thru-hike is framed as a long, demanding effort; the route’s difficulty reflects steep, rocky terrain rather than just distance. The trail uses a white blaze system (including white painted rectangles and white blazes/signage) and carries an alternate naming style associated with NET and M&M/RFT (white/blue/orange) markings.

Key landmark context on the M&M Trail includes the Holyoke and Mount Tom ranges (including the “Seven Sisters” area on the Holyoke Range), and later the Mount Monadnock summit area with its large, bare topography. The overall route also traverses multiple communities along the Massachusetts side before reaching New Hampshire.

Trail use is primarily hiking; winter use can include snowshoeing, and portions are also used by other non-motorized users in appropriate places. Surface mapping for this route is generally dirt/footpath style rather than road walking.

Maintenance and corridor upkeep for the trail’s northern/western segments are handled through local volunteer efforts connected with the Berkshire Chapter of the Appalachian Mountain Club, supporting clearing and preservation of the hiking route across rough ridges and steep ledge country.
