The Metacomet Ridge, Metacomet Ridge Mountains, or Metacomet Range of southern New England, United States, is a narrow and steep fault-block mountain ridge known for its extensive cliff faces, scenic vistas, microclimate ecosystems, and communities of plants considered rare or endangered. An important recreation resource located within of a population corridor of over 1.5 million people, the ridge is home to four long-distance hiking trails and over a dozen parks and recreation areas including several state and nationally recognized historic sites. Because of its natural, historic, and recreational value, the ridge has been the focus of ongoing conservation efforts involving municipal, state, and national agencies and nearly two dozen non-profit organizations.
