Luxor is high on your priority list: it has some of the most important archeological attractions of the world. The Valley of the Kings, the Valley of the Queens and the Tombs of the Noble are unique highlights of the ancient Egyptian Civilization. These complexes of graves and tombs are located 20 km west of town, at the other side of the Nile. The most famous of these tombs is of course that of Tutankamon.
The modern town is nothing special but not unpleasant. There are a few restaurants where you can get decent food, accommodation options range from cheap to quite expensive. For those looking for a beer, the most expensive places are the best option.
