The harsh, lunar landscape of the Valley of the Kings is the resting place of numerous New Kingdom pharaohs, whose remains were interred in tombs burrowed into rock. The 60-odd tombs which have been discovered (which may represent only half of the total tombs in the area) are identified by number rather than the name of their original inhabitant, and a handful of tombs are closed at any one time for restoration. Nonetheless there is more than enough to see, and it is better to pick out a representative sample rather than try to see every tomb.
Grave-robbers and museums have nabbed the items which were supposed to accompany rulers into the afterlife, but you can still see the work of some of the finest artisans of the ancient world, who glorified pharaohs in frescoes and wall reliefs. Graffiti shows that this extraordinary ensemble of antiquities was already a tourist attraction for the ancient Greeks and Romans.
The Valley of the Kings is beyond the West Bank of the Nile, behind the Temple of Hatshepsut. Taxis can drop you at the ticket office; from there it's a short tram ride to the first tomb.
