City Climb, the highest external building climb in the world, is a one-of-a-kind aerial adventure experience. Located above Edge,a cantilevered, glass floor protrusion attached at the 100th floor, is the highest outdoor sky deck in the Western Hemisphere,
The opportunity is to climb from the Edge up to the top of the building. Climbers get to scale the outside of a skyscraper more than 1,200 feet above the ground, then lean out and look down from the highest outdoor platform in New York City.
It’s an adventure unlike any other in the world and an achievement that you will remember for the rest of your life.
All Climbers must have a blood-alcohol reading below 0.080 in order to participate in City Climb. During check-in, all City Climb participants will be breathalyzed. Any Climber who tests over the allowable limit will not be permitted to climb. If a Climber refuses to be breathalyzed, they will not be able to participate, and their ticket will not be refunded.
According to Architectural Digest the participants will climb and descend a total of 370 steps during the 90 minute – 2-hour experience.
They test us for alcohol, make us swear we’re not on drugs and then suit us up in a one piece – they do not want one item to possibly fall off our bodies or pockets – that would not go well for someone on 
the street.
Heading up from the Edge deck.
As we head up, Mona is tentative at first.
We’re hanging on a double banister, and we are attached via harness, so it’s safe, but what mountaineers would call “exposed.” We’re about 1100’ above the street and the building is straight down on the left.
We are at the top, a small, metal-grid platform 1200’ above terra firma.
Here is a video with clips of the whole experience. https://www.dropbox.com/s/8v8mhoac56xbafl/City%20Climb%20Final%20Video.mp4?dl=0
Then we are given the “opportunity” to rely on our belay and hang over the edge – as you see in the video, we really had to think that one through. It’s not hard, but it is mental.
We head back down another set of stairs, into the building, un-suit and here we are doing a selfie at the deck with at least glass between us and 1000’ down.
It’s not a fourteener, but the thrill is there!
