Hua Shan is one of China’s Five Sacred Daoist Mountains. It’s also known for having one of the world’s most dangerous “hiking” trails.
The most dangerous part of the trail is a side trail to a small shrine. That trail consists of a descent down a “ladder” made of steel bars set into a crack in the side of the mountain, then a series of horizontal steps carved into the side of the mountain along with planks on top of supports drilled into the mountain. This section is appropriately named “Floating-in-air Road.”
