Amazing 102 floor high views of NY from Lower tip. Views over the Statue of Liberty and Ellis Island one way and the rest of Manhattan the other direction. Fairly expensive tickets but amazing on a clear day. Perfect place to go on same day as Statue of Liberty tour or when you go to the 9/11 Memorial and museum (also a must do). Personally, my favourite hi view is still the Empire State Building. Only 86 floors, but right in the centre of town and you can actually go outside on to the balcony and hear NYC below which I find more exciting than the Observatory. Maybe you'll just have to do both and compare for yourself!
