The Metacomet-Monadnock Trail (M&M Trail) is a 114-mile-long (183 km) hiking trail that traverses the Metacomet Ridge of the Pioneer Valley region of Massachusetts and the central uplands of Massachusetts and southern New Hampshire. Although less than 70 miles (110 km) from Boston and other large population centers, the trail is considered remarkably rural and scenic and includes many areas of unique ecologic, historic, and geologic interest. Notable features include waterfalls, dramatic cliff faces, exposed mountain summits, woodlands, swamps, lakes, river floodplain, farmland, significant historic sites, and the summits of Mount Monadnock, Mount Tom and Mount Holyoke. The Metacomet-Monadnock Trail is maintained largely through the efforts of the Berkshire Chapter of the Appalachian Mount
