This is a must see for any tourist in New York. I go there time and time again and though I am a New Yorker, the experience is still just as magical every time. It is located at 350 5th Ave. New York City, New York. This historic landmark is 1,453 feet and 8 9/16th inches to the tip of the broadcast tower. There are 103 floors, and it sits on approximately 2 Acres of land. But not to worry, there are 73 elevators. The Observatory is open every day, including weekends and holidays from 8am to 2am. You can go on their web site to buy tickets.
