Heights: You either love them or wither at the thought of them. If you fall into the phobic category like I do, you’re probably not apt ever to ride a glass-bottomed hot air balloon or swim in the glass-bottomed swimming pool that a British developer recently announced that he’ll construct 10 stories up, spanning two London apartment buildings.
I don’t see those activities in my future. But maybe one day I could stroll across a high-in the-sky glass skywalk. Here are six skywalks I’d like to cross, in order from highest to lowest, if I ever find the nerve:
Tianmen Skywalk, China
Before you jaunt across the glass-bottomed walkway hugging the cliffs of Tianmen (“Heavenly Gate”) Mountain in the Hunan Province of China, you must wrap your shoes in protective booties. This ensures the glass stays clean, so that you can clearly see all 4,700 feet down. (But is it slippery?)
Grand Canyon Skywalk, U.S.A.
Run by the Hualapai Nation on the western side of the Grand Canyon, the Skywalk is a horseshoe-shaped glass walkway that juts 70 feet from the edge of the canyon and 4,000 feet above the riverbed below.
Shanghai World Financial Center Observatory, China
The observation deck of this skyscraper contains a 180-foot-long glass-bottomed walkway that soars more than 1,400 feet in the air.
Glacier Skywalk, Canada
In a horseshoe shape like the Grand Canyon skywalk, this walkway overlooks the Columbia Icefield in the Canadian Rockies. It’s only 918 feet to the valley below. Only.
Dachstein Glacier Skywalk, Austria
This alpine walkway sits aside a glacier 820 feet up the side of a sheer rock-walked mountain. You have to take a steep gondola ride to get there, and there’s a gut-churning suspension bridge too.
Tower Bridge Glass Floor, England
It sits a mere 138 feet above the River Thames in London, but looking down on the zooming-by bridge traffic below you will make you feel dizzy. One of the coolest times to be there is during a bridge lift.
