It is a scenic spot in Lookout mountain, a waterfall in the mountain that was dug down from the top of the mountain that year. Take the elevator down when visiting. Imagine that the husband who dug a hole back then took his wife Ruby to climb for a few hours to watch the waterfall. This wife has a good appetite and body. The cross-section of the tunnel from that year is also retained. Climb inside and see if your knees will crawl. The lights and music at the waterfall are only on for seven minutes, so you need to hurry up and take pictures. It is best to turn on the flash of the mobile phone or remove the mobile phone cover in advance (some mobile phone cases will cause reflections and affect the shooting effect) to save some time.
Underground rubies, such as jewels, exude fascinating beauty. When you come to Tennessee, the first thing you have to sigh is its vast land and sparse population and simple folk customs. This place is basically the same as the American countryside in our impression, and it is very original. On the second day of coming to Tennessee, we set off to visit the beautiful scenery. On this day, I came to the underground waterfall that is known as the largest and deepest in the United States and is open to tourists. When we heard this underground waterfall, we immediately became interested. The waterfalls you see on weekdays are all on the ground, what would this underground waterfall look like! After entering the cave, I have to feel that there is really a cave in it, it is an underground world! On both sides of the walkway are stalactites, stalagmites, stone pillars and other necessary "specialties" in caves. Walking around, we finally came to our most curious place-Ruby Falls! This waterfall gushes down from the towering rocks on both sides, changing colors from time to time under the light of light: red, yellow, green, etc. Seeing this, I can't help but remind me of the Devildom World in the TV series I watched when I was a kid. It was really interesting! I don't know where the source of this waterfall is, maybe it is the underground river? We can't tell. Warm reminder that the temperature in the underground cave is lower than that on the ground. It is recommended to bring a thin coat.
