It is an attraction in Lookout mountain , which was an inner mountain waterfall that was dug down from the top of the mountain. Take the elevator to go down when you visit. Imagine that the husband who dug the hole with his wife Ruby climbed for hours to see the waterfall, and the wife's appetite and body were good enough. It also retained the cross section of the tunnel. Climb inside and see that the knees will crawl. The waterfall lights and music are only open for seven minutes, and you need to take pictures. It is best to turn on the mobile phone flash in advance or remove the mobile phone cover (some mobile phone shells will cause reflection and affect the shooting effect) to save time.
