Introduction to the Immortal Valley: The Immortal Valley is a canyon about 2 kilometers long between Wangtiantai and Wolong Peak. It extends to the bank of the Xiangzi River. The narrowest point is less than half a meter, and can only allow one person to pass sideways. Standing at the bottom of the canyon and looking up, you can only see a sliver of sky. According to legend, those who are destined can meet immortals walking here.
