The world's highest and longest glass-bottomed bridge opened last Saturday in China's Zhangjiajie mountains - the inspiration for blockbuster movie Avatar.
Some 430m long and suspended 300m above ground, the bridge spans the canyon between two mountain cliffs in Zhangjiajie park in central Hunan province.
The bridge, 6m wide and made of 99 panels of clear glass, can carry up to 800 people at a time, an official in Zhangjiajie told the Xinhua news agency.
Tourists can walk across the bridge, designed by Israeli architect Haim Dotan, and the more adventurous will be able to bungee jump or ride a zip line.
Only 8,000 people will be allowed to cross the bridge each day, Xinhua said, and tourists will have to book tickets a day in advance, at a cost of 138 yuan (S$28).
Cameras and selfie sticks are banned, and people wearing stilettos will not be allowed on the bridge.
