Blue Hills Reservation is a 6,000acre state park in Norfolk County, Massachusetts. Managed by the Massachusetts Department of Conservation and Recreation, it covers parts of Milton, Quincy, Braintree, Canton, Randolph, and Dedham. Located approximately ten miles south of downtown Boston, the reservation is one of the largest parcels of undeveloped conservation land within the metropolitan area. The park's varied terrain and scenic views make it a popular destination for hikers from the Boston area.HistoryEuropean explorers sailing the coastline noticed the bluish hue of the mountains, which is caused by the presence of riebeckite, which gave area its modern name. The name of the state of Massachusetts derives from the Massachusett Indian tribe's name of the hill: massa-adchu-es-et. In 1893, the Metropolitan Parks Commission purchased the lands of Blue Hills Reservation as one of the state's first areas dedicated to public recreation.
