Introduction to Feiwu Cave: Feiwu Cave is the most famous attraction in Feiwu Valley, also known as Luoshui Cave and Luohong Cave. It consists of two funnel-shaped vertical holes facing the sky. Above it is the upper falling water, and below it is the lowering water. There is a pool under the cave, and the water in the pool is the collection of the three springs in the Green Ridge Corridor. There is a secret passage between the two caves, which is actually a natural bridge. It is more than 30 meters long, more than 20 meters high, and about 5 meters wide. Walking on it is full of mystery. The pool in the cave can be used to cross bamboo rafts; there is fog in the cave, and when it clears up after the rain, the fog slowly rises; when the sky is clear, the sun shines into the cave, and rainbows often appear; these three scenes are called "Flying Fog Cave Three" Absolutely".
