Vanderbilt is a beautiful mansion located in Hyde Park, New York. The mansion is situated on the east bank of the Hudson river. The grounds are scenic, and include magnificent gardens. There is a trail going through the woods, that can take you back up to the mansion. It is a steep climb, but still fun if your knees can take it. The way down to the river from the free parking areas is steep as well, but is paved and sometimes open to traffic, though not always. There is a picnic spot up above as well, from which you can see the Hudson River.
