The New England National Scenic Trail (NET) is a National Scenic Trail in southern New England, which includes most of the three single trails Metacomet-Monadnock Trail, Mattabesett Trail and Metacomet Trail. After the Metacomet-Monadnock-Mattabesett trail system, the trail is sometimes called the Triple-M Trail. The route extends through 41 communities from Guilford, Connecticut at Long Island Sound over the Metacomet Ridge, through the highlands of the Pioneer Valley of Massachusetts, to the New Hampshire state border. (The remainder of the M-M Trail to the summit of Mount Monadnock in southern New Hampshire is not included in the designation.) This includes a now (2013) complete connector trail (the Menunkatuck Trail) from the southernmost location of the Mattabesett Trail (in northern Guilford, Connecticut) to the sea (Long Island Sound) and a deviation of the Metacomet-Monadnock Trail in Massachusetts, to lead the trail through state-owned land instead of largely unprotected land.
