Hell Canyon of Kasi is located on the west side of Yangmaiyong Snow Mountain, south from Kasi Village and east to the south slope of Xiannai. There are many cliffs in the canyon, and the dolomite at the tail of the canyon is weathered into a sickle, a knife and a gun. It is similar to the description of various kinds of torture in hell. Hell Canyon is named after it. The scenery in Hell Canyon is superb, with strange rocks and virgin forests. Spring waterfalls can be seen everywhere.
