Ancient pyramids, colorful bazaars and temples that were already ancient by the time Cleopatra took charge only begin to describe the highlights of a Nile River cruise through Egypt. Itineraries generally include tours of landmark sights in Cairo, Luxor and Aswan, as well as visits to more secluded temples such as Abu Simbel. With so many things to see, a Nile River cruise includes plenty of tours, but there's also time to relax and watch the world float by.
