This is on Hua Shan mountain in Shaanxi Province, not far from the city of Xi'an (with the Terra Cotta warriors). A fantastic set of 5 peaks, linked by paths and stone steps. My wife climbed partway along that wooden walkway (in the rain!) after we spent the night at the rough hotel at the top. You borrow a simple harness to clip in to the chains. The main peaks have thousands of visitors - many hiking in dress shoes and high heels! All supplies are carried up by workers straining to lift massive bags full of food, drinks, and souvenirs to the shops on the route.

Supposedly James Cameron visited and was inspired to model the floating mountains of Pandora after these peaks.
