Walking on thin air

Wednesday December 07, 2011 Written by nadia

A new walkway at Tianmen Mountain National Park in China puts two-and-a-half inches of glass between visitors and a crapload of thin air.

Unveiled early November, the 61-metre-long walkway hangs over the UNESCO world heritage site, offering views across the national park and straight down the cliff face.

While not high enough to warrant altitude sickness, at 1,430 meters above sea level the walkway is still at a gut flipping height. Visitors need to wear "anti-slip" shoe covers to ensure that the glass doesn't get dirty... and, god willing, so they don't slip.
