Embark on a voyage of discovery as you journey down alongside the banks of the River Nile, thought to be the longest river in the world. The Nile has served as Egypt's lifeline since ancient times and there is no better way to trace the course of Egypt's history than to follow the course of the river. Egypt's tourist capital, Luxor, has been called the world's greatest outdoor museum, as it is home to many of Egypt's most well known temples and tombs, including the Valley of the Kings, home to Tutankhamun's tomb. Aswan is also well worth a visit to see the world's largest manmade lake, and to soak up some of the hot desert sun. South of Luxor, in Edfu, stands one of Egypt's best preserved temples, built by the father of Cleopatra.
