The most famous example of prehistoric rock art in the Gilf Kebir is at Wadi Sura. The Valley of the Picture, in the northwestern Gilf, contains the Cave of the Swimmers. There is some dispute over who actually found the Cave first. It seems likely that P.A. Clayton on his early surveying expedition found the Wadi itself but didn't enter the actual cave where the painting is. This honour went to the Hungarian explorer, Count Almasy, now better known as The English Patient. In the Cave of the Swimmers there are a large number of paintings some of which are damaged. They show a range of animals including giraffes, ostriches and dogs. The majority show men. They are not delicate or anatomically correct but they are clearly men. A group of them are clearly floating in water, diving and swimming. This gives a definite indication that there was once a lake nearby. There are other caves containing paintings in the same wadi but it is the weightless charm of the swimmers that has captivated the imagination of visitors to this area.
