Hua Shan, located in the Shaanxi Province, China, is considered one of the most challenging routes in the country. The mountain, called Mount Hua, is one of Five Sacred Taoist Mountains and has a long history of religious significance. Today, the plank pathway leading all the way up to the peak has become a paid tourist attraction. Before the 1990s the route was actually very dangerous, but since the boom in tourism the local government has installed some railings and built wider paths and stone steps.
Still, the Hua Shan trail is considered to be the most dangerous tourist mountain route in the world.
