The Stone Gate Gorge in Ailao Mountain is deep and dark, not for the faint-hearted.

This is probably one of the most beautiful gorges I've ever been to, located in the heart of Ailao Mountain in Gasai Town, Xinping County. If the gorge in Jiuzhaigou is "strange" and "beautiful", then this gorge is "secluded". "Even if it is sunny and rainless, it will get wet when entering the cloud" is a true portrayal of the real environment of this gorge. The gorge is not long, about 2.8 kilometers, but it is very narrow, a few meters at the narrowest point, and no more than 30 meters at the widest point. The primitive forests on both sides are covered with clouds and the sun is hard to project in. Whether it is sunny or cloudy, the light is dim. Along the way, you will accidentally encounter ancient trees lying on the stone path and springs flowing down, making the stone path wet. The turbulent mountain stream in the middle is clear and cool, the water volume is very large, everything makes this place extremely deep.
