One World Observatory might be the one of the hottest attractions in New York City. The views from One World Trade Center are unparralled. The Observatory sits on levels 100-102 of the the tallest in the Western Hemisphere. On the way to the observation decks you'll enjoy a time-lapse transformation of NYC displayed on digital screens on all four walls of the elevator. Once on the decks the 360-degree views of the city will take your breath away. See for yourself why One World Observatory is truly An Experience Above.
