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 215 mi 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.
This trail system is a part of the Connecticut 400, one of the official Blue-Blazed (or similar) trails listed in the Connecticut Walk Book by the Connecticut Forest and Park Association (CFPA) and recognized, since 1976, with an award known as the "Connecticut 400 Club" by the Connecticut Chapter of the Appalachian Mountain Club (AMC).
 In 1976 there were only four hundred miles of Blue-Blazed trail but today (2010) the total length of the trails listed in the CFPA Connecticut Walk Books (East and West) exceeds 825 miles.
The Metacomet-Monadnock Trail (M&M Trail) is a 114 mi 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 mi 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 Mountain Club (AMC).
 Much of the trail (but not all) is a portion of the New England National Scenic Trail.
Hiking in Connecticut consists of many individual and networked trails that include over 800 miles of Blue-Blazed Trails maintained and operated by the Connecticut Forest and Park Association.
