Introduction to Luyou Ancient Cave: Luyou Ancient Cave is located on the north bank of the intersection of the west entrance of Wu Gorge and the Daning River. It was named because the poet Lu You came to Shu in the sixth year of Emperor Xiaozong's reign in the Song Dynasty and stayed in this cave. Luyou Cave consists of three ancient caves: Qingshui, Jinzhu and Yulin. The three caves are both independent and connected. The stalactites in the cave are in various shapes and forms, which is amazing.
