The New York City Department of Parks & Recreation is New York City's principal provider of recreational and athletic facilities and programs. NYC parks are home to free concerts, world-class sports events, and cultural festivals. Parks & Recreation is the steward of nearly 20 percent of New York City's land, including thousands of individual properties ranging from Coney Island Beach and Central Park to community gardens and Greenstreets. Parks & Recreation operates athletic fields, playgrounds, tennis courts, public pools, recreational facilities, nature centers, golf courses, and beaches throughout the five boroughs. Parks & Recreation also cares for monuments and historic house museums and look after hundreds of thousands of street trees (even more within parks).
