The only entrance must pass through the narrow cliff walls, towering and winding paths leading to the 1.5 km long "Xike Canyon" masterpiece of nature, the widest 7 meters and the narrowest 2 meters bending, more than 100 meters of cliff walls shielding the hot sun, the canyon is bright and dark mottled land, and the end of the snake path is "Temple". This natural Rift Valley is vividly called Snake Way.
