Shiba Pan, or Eighteen Twists is the steepest and most splendid part among all the parts of the ancient mountaineering path. It is like a scaling ladder from the heaven, connecting the bottom with the Southern Heavenly Gate. There are more than 1600 steps here with the length less than 1 km. But the upright height is more than 400 meters.
