Guangdong Grand Canyon lies in Dabu Town, Yao Autonomous County of Ruyan, 70 kilometers away from the Ruyuan exit of Jingzhu Highway. The canyon, one of the quartz sandstone canyon landforms, is 15 kilometer long, more than 300 meters deep. The bottom of the canyon is smooth and the Hukou Waterfall washes the valley bottom from more than 200 meters of disconnected precipices directly, creating the impressive Chengtou Waterfall. There is a ¡°sky ladder¡± with 1386 stone steps reaching the bottom at a bevel of 50 degrees. The gully is vertical-horizontal, the grotesque peak stands in great numbers, and the ancient wood reaches to the sky. It is really a wonderful workmanship here.
