Nyack Beach State Park is a 76acre state park in Upper Nyack, Rockland County, New York. It consists of a small parking lot and 61acre of riverfront pathway, the southernmost section of the Hudson River Valley Greenway. It is known for its physical proximity to the Hudson River on one side of the pathway and the looming cliffs of the Palisades rising 700ft above on the other side.The park is included within the Palisades Interstate Park system and is functionally part of a continuous complex of parks that also includes Rockland Lake State Park, Hook Mountain State Park, and Haverstraw Beach State Park.HistoryThe Palisades Interstate Park Commission purchased what was to become Nyack Beach State Park in 1911 to provide space for recreation, and to protect the land from the effects of quarrying that were impacting the Hudson River Palisades during the late 19th and early 20th centuries.Along with a portion of adjacent Hook Mountain State Park, Nyack Beach was declared a National Natural Landmark in April 1980 for its portion of the Palisades Sill.
