The Immortal Canyon is the most majestic granite canyon in Sanqingshan thanks to its magnificently precipitous landform. The canyon stretching over 2,500m is V-shaped when viewed  from its fault surface and it plunges to a depth of over 300m. In addition to its cliff flanks, it is notable because people are denied access to it. As only the Immortal can fly across it, the canyon is named "the Immortal Canyon". The V-shaped canyon was formed when running water rushed and eroded the granite body along its fractures.
