Experts advise on the development of tourism.

"The geological structure here belongs to the axis of ancient Kangdian, and there are various Archean metamorphic rock series and late magmatic intrusions. They are exposed on both sides of the canyon, just like a natural geological museum. " You Lianyuan (a researcher at the Institute of Geographical Sciences and Resources, Chinese Academy of Sciences) gave such an evaluation of the Grand Canyon.

Dadu River Grand Canyon is located in the area where the crust on the eastern edge of Hengduan Mountains is strongly uplifted. The bedrock of the canyon is mainly hard dolomitic limestone, which has become the largest and most typical peak and valley on the river in China. The valley slope is vertical, the valley is deep and narrow, and the valley bottom is almost occupied by rivers, with no floodplain. The flowing water collides and churns in such a canyon, and the waves splash, and the sound is like thunder, the sound is like a tiger roar, and the sound is like a cracked mountain ... Fan Xiao said: "In this torrent roar, it seems to be surrounded by the most powerful music like Beethoven's heroic symphony, and it is impossible to stop it from entering the ranks of the most beautiful places in China and voting for it."

The surging torrent of the Dadu River Grand Canyon is the blood of the earth. In the face of this canyon, you can only think of the word "surging", and you may even think that this word is made for this canyon. Fan Xiao said: "The Dadu River Grand Canyon integrates canyons, rapids, peaks, lakes, typical geological sections, rare animals and plants, and cultural relics. It is the best geological landscape and eco-tourism base, and it can be built into the largest natural rock climbing exploration base in western China. "
