The much-heralded "world's highest and longest" glass-bottomed bridge has opened to visitors in central China.

It connects two mountain cliffs in what are known as the Avatar mountains (the film was shot here) in Zhangjiajie, Hunan province.

Completed in December, the 430m-long bridge cost $3.4m (£2.6m) to build and stands 300m above ground, state news agency Xinhua reported.

It has been paved with 99 panes of three-layered transparent glass.

And according to officials, the 6m-wide bridge - designed by Israeli architect Haim Dotan - has already set world records for its architecture and construction.

Park officials have said a maximum of 8,000 visitors will be allowed on the bridge each day.

So those wanting to add another thrill to their bucket list are strongly encouraged to book their slots in advance.
