Luxor, once Thebes, the capital of Ancient Egypt, is known as the "greatest open air museum in the world." Egypt's top tourist destination is home to sites such as the Temple of Karnak - a city of temples built over 2000 years, and the Luxor temple complex. Across the Nile lies the Valley of Kings, with more than 60 royal tombs, and the Valley of Queens, with the tomb of Nefertari. See the astounding sites by private limo and driver or soar above monumental ruins on a hot air balloon ride.
