Tourists on camelback ride in a line across the sandy desert plateau at Giza, with the massive limestone face of the Great Pyramid dominating the background. Camel riding is one of the most popular traditional tourist activities at the Giza Necropolis, offering visitors a ground-level view of the ancient monuments. The Pyramids of Giza, built during the Fourth Dynasty of the Old Kingdom (circa 2580–2560 BC), are the only surviving wonder of the ancient world and a UNESCO World Heritage Site.
