Colored Canyon, Sinai, Egypt

The tall walls of Colored Canyon reveal the source of the name. Sinai was once covered by ocean, which left layer upon layer of sediment to be eroded away by water and wind over millions of years. Those layers reveal diverse colors — reds, magentas, purples, golds and yellows, sometimes with a metallic sheen — can in places look something like The Wave, which is a continent away. The walls rise to heights of over 100 feet in some places, and is sometimes only a few feet wide. It is a relatively easy hike, and as a result is a popular destination for tourists.
