Top of the Rock has three upper observation decks, 850+ feet above street level, on the 67th, 69th, and 70th floors.
Views are great in all directions, but one of the best is this angle above, looking out over Frederick Law Olmsted's masterpiece of urban planning, Central Park. Other fine sights include: the Chrysler Building, Brooklyn Bridge, and the Hudson and East Rivers. Check out the audio podcast that can add interesting details and background.
