Introduction to the Sky Ladder Plank Road: The Sky Ladder Plank Road has a total of 1,680 levels, with a very steep slope and very narrow wooden planks. The plank road extends downward one after another, like a ladder to heaven, transporting tourists to a charming wonderland. On both sides of the Tianti Ladder Plank Road, you can see thousand-year-old ancient vines, "women singing with their husbands", "family portraits", cracks in stone walls, "Zhangjiajie brand natural air conditioners", "forests growing on stones" and other wonders.
