West Rock Ridge State Park is a public recreation area located in New Haven, Hamden, and Woodbridge, Connecticut. The state park is named for the 400-to-700-foot (120 to 210 m) trap rock West Rock Ridge, which is part of the Metacomet Ridge extending from Long Island Sound to the Vermont border. The park's 7 miles (11 km) of open west-facing cliffs offer vistas encompassing Metropolitan New Haven and suburban towns to the west. The park includes Judges Cave, a colonial era historic site; Lake Wintergreen; and the 7-mile (11 km) Regicides Trail, part of the Connecticut Forest and Park Association's Blue Trail system. The park is part of a larger area of protected open space including state, municipal, and non-profit owned land.
