Visitors to Shanghai's 340-meter-high Skywalk held only by safety harness
Dachstein Stairway to Nothingness in Austria straddles a drop of 1,300 feet
Think you can handle a 340-meter-high, open-air glass walkway?
Shanghai Skywalk, which was unveiled in July, is the latest daredevil challenge for fear-free travelers.
1. Shanghai Skywalk (China)
At Shanghai’s 88-story Jin Mao Tower, visitors will be able to walk around a new glass walkway on the outside of the building, 340 meters above the city.
Tickets aren’t yet on general sale – and there’s no confirmation when they will be – but when CNN visited Shanghai for travel series “In 24 Hours,” host James Williams just had to try it out.
