The new Observatory at the top of One World Trade Centre has opened its booking engine for those wishing to visit as soon as it opens on 28 May.

It’s not a cheap experience, with the basic tickets (for timed entry) are priced at – Adult $32, Senior $30, Child $26

It does look like an extraordinary experience. I still have found memories of my first visit to the top of the World Trade Centre during my first visit to New York in the 1980’s. Destroyed on 9/11, the new Observatory seeks to provide a unique experience.

There are some more flexible options, all at higher prices. These passes allows guests who are looking to go straight to the top with the option to access a separate private pathway to the Observatory elevators (direct pathway to elevators not recommended for first-time visitors as part of the experience is bypassed).
