Wadi El-Hitan Protected Area is a UNESCO World Heritage site, a valley that was more than a million years ago a sea with a wide variety of marine life. It now contains fossils & skeletons of now extinct whales, along with rock formations that are best enjoyed at break of dawn. There is a Wadi El-Hitan museum located near Garet Gohannam north-west of Wadi El-Rayan that has hundreds of skeletons of now extinct whales as well.
