Hudson River Park is a waterfront park on the North River that extends from 59th Street south to Battery Park in the New York City borough of Manhattan. The park, a component of the Manhattan Waterfront Greenway, stretches 4.5 miles and comprises 550 acres, making it the second-largest park in Manhattan after the 843-acre Central Park. Hudson River Park is a joint state and city collaboration, but is organized as a New York State public-benefit corporation.
