Sunken Meadow State Park, located at the northern terminus of Sunken Meadow Parkway north of NY 25A in Kings Park, is an underrated choice. It may be less beautiful or popular as Jones Beach, but if you don't want the crowds, this is a good choice. However, Smith Point County Park in Mastic Beach, Robert Moses State Park in Bay Shore/West Islip or Heckscher State Park in East Islip are better choices.
