12. Wharfe River (United Kingdom)
The river number 12 on our list of scariest deadliest rivers in the world is considered to be the deadliest river in England. The fraction of the river known as Bolton Strid which is about 6 feet wide hides the darkest secret. Beneath the river’s tranquil appearance lies a treacherously fast current rushing over a deep underwater channel and undercut, rocky banks that make it difficult to climb out of if you do fall in. It’s the cause of many fatalities and poems has been written about its deadly flow.
