Waterfalls are the most exquisite of natural wonders. They bring about a feeling of freshness that can only be experienced. After all, it is not everyday that you get to witness torrential water fall over rocks, creating pools of deep blue.
Waterfalls are of various kinds. Some are gigantic, creating thunderous sounds as you feel their cool breeze from a distance. Then there are the hidden, meandering ones – for which you need to dive inside caves and descend into underground tunnels. The Ruby Falls, located inside Lookout Mountain, in Tennessee, USA, are one such phenomenon!
