Introduction to Huangniu Gorge: Huangniu Gorge is located between Liantuo and Nanjinguan. Not long after passing Dengying Gorge, you can see a row of steep rock walls. This rock wall is Huangniu Rock, and the river valley is "Huangniu Gorge". Compared with Dengying Gorge, the mountains on both sides of Huangniu Gorge are towering and the rock shapes are rough and changeable. This is a representative Sinian geological fault.
