The Bailong Elevator is probably the worlds most extreme elevator at the moment and I feel pretty confident when saying this. The elevator is located inside the World Heritage site Zhangjiajie National Forest Park in China. The glass elevator runs along a cliff face and stretches 326 meters high (1,070 feet). The first 154 meters runs through a underground shaft and the rest 172 meters outside the summit. The elevator takes 50 people per ride and takes about 2 minutes from top to bottom giving it a daily capacity of 18,000 people.
It is the highest and heaviest outdoor elevator in the world but is facing an uncertain future since it was built in 1999 without consulting the World Heritage Committee and the construction of new structures are forbidden. The claim is that it is causing harm to it’s surrounding landscape.
