Waterfalls in caves prove that constant pounding is not like making a hole in water. Often, they have flowed over the same rock for so many hundreds of years that it finally did cave in and let the water have its way. Or, the rock was porous to begin with and rivers and streams quickly made their way in. Though popular in the virtual and gaming world, waterfalls inside caves are not very common in the real world – if you’re not counting trickles and caves behind waterfalls. We’ve found five around the world that made the cut.

Smoo Cave is unique because it has three distinct sections that developed independently of each other: The entrance chamber was formed through erosion by the sea; a freshwater passage and a second chamber by an inland underground stream; and a waterfall chamber.
