Take a taxi or bus from Tangkou to the Eastern steps and start walking (or wimp out and take the cable car!)
Beautiful place. Just be prepared for lots of steps up and down.
Yellow Mountain (Huangshan) in Anhui Province, has the reputation of being the most beautiful mountain in the world. I travelled with Dan from Los Angeles who said that Yosemite would have to take 2nd place to Huangshan! He loves Yosemite. The views (and the effort to get to them) were dramatic.
