The Valley of the Kings, also known as the Valley of the Gates of the Kings, is a valley in Egypt where, for a period of nearly 500 years from the 16th to 11th century BC, rock-cut tombs were excavated for the pharaohs and powerful nobles of the New Kingdom (the Eighteenth to the Twentieth Dynasties of Ancient Egypt).
This area has been a focus of archaeological and Egyptological exploration since the end of the eighteenth century, and its tombs and burials continue to stimulate research and interest. Since the 1920s, the valley has been famous for the discovery of the tomb of Tutankhamun and is one of the most famous archaeological sites in the world. In 1979, it became a World Heritage Site, along with the rest of the Theban Necropolis. Exploration, excavation, and conservation continue in the valley, and a new tourist center has recently been opened.
The valley has been a major focus of modern Egyptological exploration for the last two centuries. Prior to this time, it was a site for tourism in antiquity (especially during Roman times). The area illustrates the changes in the study of ancient Egypt, starting with antiquity hunting, and ending with the scientific excavation of the whole Theban Necropolis. Despite the exploration and investigation noted below, only eleven of the tombs have actually been completely recorded.
A visit here is a highlight of any Egypt trip but can be demanding due to the stifling heat and swarms of visitors. It’s important to note that tombs open and close to the public in rotation in an attempt to help preserve the wall paintings, which have suffered severe degradation from the humidity caused by so many visitors.
The road into the Valley of the Kings is a gradual, dry, hot climb, so be prepared, especially if you are riding a bicycle. Also be prepared to run the gauntlet of the tourist bazaar, which sells soft drinks, ice creams, and snacks alongside the tat. The air-conditioned Valley of the Kings Visitors Centre & Ticket Booth has a good model of the valley, a movie about Carter’s discovery of the tomb of Tutankhamun, and toilets (there are Portakabins higher up, but this is the one to use). A tuf-tuf (a little electrical train) ferries visitors between the visitor’s center and the tombs (it can be hot during summer). The ride costs LE4. It’s worth having a torch to illuminate badly lit areas but you cannot take a camera – photography is forbidden in all tombs.
