Parks and recreation

Boston Common, near the Financial District and Beacon Hill, is the oldest public park in the United States. Along with the adjacent Boston Public Garden, it is part of the Emerald Necklace, a string of parks designed by Frederick Law Olmsted to run through the city. The Emerald Necklace includes the Back Bay Fens, Arnold Arboretum, Jamaica Pond, Boston's largest body of freshwater, and Franklin Park, the city's largest park and home of the Franklin Park Zoo. Another major park is the Esplanade, along the banks of the Charles River. The Hatch Shell, an outdoor concert venue, is adjacent to the Charles River Esplanade. Other parks are scattered throughout the city, with major parks and beaches near Castle Island and the south end, in Charlestown and along the Dorchester, South Boston, and East Boston shorelines.

Boston's park system is well-reputed nationally. In its 2013 ParkScore ranking, The Trust for Public Land reported Boston was tied with Sacramento and San Francisco for having the third-best park system among the 50 most populous U.S. cities. ParkScore ranks city park systems by a formula that analyzes the city's median park size, park acres as percent of city area, the percent of residents within a half-mile of a park, spending of park services per resident, and the number of playgrounds per 10,000 residents.
