I thought these photos were fake until I did some snooping, and discovered to my amazement that they are very real.
They were taken at a swimming hole known as the 'Devil's Pool' at Africa's Victoria Falls (located on the Zambezi River and border Zambia and Zimbabwe).
How can people swim in the Devils Pool without plunging to certain death? Apparently, a natural rock ledge reduces the current and stops swimmers from being swept over the edge. However, at times of the year when the water flow is greater, the ledge does not offer enough protection for swimmers and a leisurely dip is not recommended.
Check out the video clip below, it really is hard to believe.
I think I will stick to handling spiders for my adrenaline rush!
