Willson's Woods Park is a park located in Mount Vernon, New York. The Park is owned by Westchester County and operated by its Department of Parks, Recreation and Conservation. Acquired in 1924, Willson's Woods is one of the oldest parks in the County's parks system. The Park was named for the former owner of the land, Charles Hill Willson of the Willson & Adams Lumber Company. The park is flanked to the east by the Hutchinson River Parkway and by Pelham Lake. It was built with the northern entrance passing under the now defunct New York, Westchester and Boston Railway line, and the southern under the still working New Haven Line.
