It’s the really high line.
Starting Nov. 9, thrill seekers can walk almost to the tippy-top of the 1,296-foot-tall 30 Hudson Yards skyscraper in Midtown, but not from the comforts of an indoor observatory.
This trek takes visitors along the outside of the building — with no windows or other protective barriers standing between them and sky-high views of the Big Apple. They will, however, be equipped with safety harnesses.
Welcome to City Climb, a high-altitude attraction that takes up to eight daredevils and their skyscraper sherpa to a dizzying 1,271-foot-high perch, called the “Apex,” near the tower’s crown.
It begins at the building’s 100-story-high Edge observatory and only gets higher from there, with guests taken along a dizzying series of stairs and platforms that continually rise in altitude.
All it takes is $185 for a ticket and a strong stomach.
Visitors with lesser constitutions can stick to Edge — a viewing platform 1,131 feet up that’s safely ensconced by glass paneling where general admission starts at $36 for adults. There, you can step out onto a portion of glass flooring for an added thrill.
From that platform, trained guides take participants on the vertigo-inducing climb and ascend a series of steps to reach the aptly named “Apex.”
Along the way, they visit a perch named “The Cliff,” where they can look down a full 1,190 feet to the street.
The most intense portion comes during a 161-step climb up a 45-degree incline to the top.
Once they reach the zenith, climbers can get an extra thrill by leaning off the Apex’s open-air viewing platform — with nothing obstructing their panoramic views, which extend out to the Atlantic Ocean.
It’s “a chance to live out a superhero fantasy at the top of NYC,” Cassie Davison, vice president of marketing for Hudson Yards Experiences, told The Post.
Before setting out, guests must complete a safety briefing. That, combined with the total 370-step ascent and descent, lasts up to two hours.
Organizers say City Climb is also the highest external building climb in the world — but much to New York’s chagrin, it isn’t the first.
In August 2011, downtown Toronto’s CN Tower opened its EdgeWalk attraction, the first of its kind in North America. Similar to City Climb, EdgeWalk takes adrenaline-junkie visitors on a harnessed walk around the tower’s main pod 1,168 feet above that city’s own bustling streets.
Beyond bragging rights, the admission price also includes entry to Edge — where they can settle down with Champagne at its bar — and souvenirs, such as a personalized video of each person’s climb.
