It's Pelham Bay Park, which is located in the northeast corner of The Bronx, is the largest public park in New York City, more than three times the size of Central Park. It includes land on both sides of the Hutchinson River and all of Hunter Island in Long Island Sound (now also part of the mainland).
On its north is the village of Pelham Manor in Westchester County. The park borders the Bronx neighborhoods of Pelham Bay, and Co-op City. The southern part of Rodman's Neck is not part of the park but is occupied by the NYPD gun and rifle Firing Range.
