Cliffside-steps-Hunan-China

Don’t look down!! 

The TERRIFYING see-through path stuck to a Chinese cliff-face 4,000ft above a rocky ravine.

It is certainly not a path for the faint-hearted.

On one side a sheer rock face, on the other a 4,000ft drop - and all to separate the brave traveller from a deadly plunge is a 3ft-wide, 2.5in thick walkway.

And if that is not enough to bring terror into the pit of your stomach, the path running alongside a Chinese mountainside is made out of glass, allowing a crystal-clear view of where one false step can take you.

The sky walk is situated 4,700ft above sea level on the side of the Tianmen Mountain in Zhangjiajie, China.  

The 200ft long bridge joins the west cliff at the Yunmeng Fairy Summit, the summit of Tianmen Mountain and Zhang Jiajie.

And it would appear to be too scary for the cleaners - tourists are asked to put on shoe covers before passing to help keep the path clean.

The 70ft bridge is 4,000ft above the natural wonder and allows tourists to look through 2.5in of crystal-clear glass to the Canyon floor below.

The Tianmen mountain, literally translated as Heavenly Gate Mountain is so called because of a huge natural cave that occurs halfway up to the summit.

The Millau Viaduct is a cable-stayed bridge that spans the valley of the river Tarn near Millau in southern France.

Designed by the French structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest bridge in the world with one mast's summit at 343.0 metres (1,125 ft) above the base of the structure. It is the 12th highest bridge deck in the world, being 270 metres (890 ft) between the road deck and the ground below.

Millau Viaduct is part of the A75-A71 autoroute axis from Paris to Montpellier. Construction cost was approximately €400 million. It was formally dedicated on 14 December 2004, inaugurated on the 15th, and opened to traffic on the 16th. The bridge has been consistently ranked as one of the great engineering achievements of all time. The bridge received the 2006 International Association for Bridge and Structural Engineering Outstanding Structure Award.
