The largest park in Queens (and fourth largest park in all of New York City) has something for jocks, artists, nature lovers and the technologically inclined: green recreational spaces for baseball, soccer and cricket; playgrounds; skateboarding areas; handball courts; dog runs; the Queens Museum; the New York Hall of Science; the Queens Zoo; USTA Billie Jean King National Tennis Center (home of the US Open); and Citi Field, home to the Mets. A handful of features on the grounds are leftovers from world's fairs held here.
