The public can never get enough of death-defying diversions, from flagpole sitters in the 1920s to today’s ever-crazier rollers coasters. The last two “Mission Impossible” movies—which featured Tom Cruise actually scaling the outside of the Burj Khalifi and hanging onto the wing of a jet in flight—combined did nearly $1.4 billion in box office sales internationally. And one of the attractions of “extreme” sports and recreation is that the participants live to tell about it.

Thrill-seekers who happen to be in Shanghai can now literally live on the edge by dangling off of a safety rope from a 3.9-foot-wide skywalk with a see-through platform that wraps around the 88th floor of the Jin Mao Tower in Lujiazui, a peninsula locality in that metropolis.

The 60-meter (197-foot) skywalk is touted as the highest fenceless and all-transparent walkway in the world. At 1,115 feet above ground, the skywalk, which opened on July 29, provides breathtaking views of the city from a tower that is one of the world’s tallest skyscrapers.

Up to 15 visitors at a time can be harnessed to an overhead rail, and hang 10 over the ledge of the Jin Mao walkway for up to an hour. (They must sign waivers as a prerequisite, of course.) The height of the skywalk and time allowed on it outdo Macao Tower Skywalk X, which lets visitors take a 15- to 20-minute open-air stroll around the outer rim of the Macao Tower, 233 meters above the ground, according to China.org.

Skywalkers pay 388 yuan (US$58) for the Jin Mao attraction, with a discounted rate (298 yuan) for students.
