The mighty Nile has been providing Egypt with water for millennia. Deserving of its reputation as the world's largest open-air museum, the Nile River Valley contains thousands of monuments at sites such as Luxor and Aswan. Don't miss the city of temples ar Karnak, the dozens of tombs in the Valley of the Kings, the massive rock temples of Abu Simbel or vast and powerful Luxor Temple. Visitors can float by these astounding sites on a felucca boat or cruise ship or catch a train from Cairo.
