Upper Egypt (Arabic: صعيد مصر Sa'id Misr) is a region of the Nile Valley in Egypt, between Luxor and Aswan and the historical region of Lower Nubia, characterised by a number of ancient settlements and temple towns that draw thousands of travellers every year.
The towns of Upper Egypt can be accessed either by train or taxi from Luxor (to the north) or Aswan (to the south) - a trip from one of these cities to the other, popular with many travellers to Egypt, is greatly enhanced by stopping at one or more of the temple towns. Exact details differ for each town - it is worthwhile consulting the article on each for full details.
Negotiate with your taxi driver to stop in each of the towns along the way - this is a very common practice and can be easily arranged with some canny bargaining - but do note that although this part of the Nile Valley has never really been threatened by violence (unlike Middle Egypt) - the Egyptian tourist police may nonetheless insist that you travel within a police convoy.
Alternatively, a felucca cruise on the Nile between Luxor and Aswan will normally include stops at one or more of these Upper Egyptian towns.
The most convenient way to visit Upper Egypt is to take a Nile cruise. They are mostly 3, 4 or 7 nights long going from Luxor to Aswan and vice versa. There are approx. 300 ships but the best best is to go with a branded line such as Movenpick Royal Lily or Royal Lotus. During the cruise the ship stops in Luxor, Esna, Edfu, Kom Ombo and Aswan. From the ship you go on excursions to the museums and temples in each town. Staying a few extra nights in Luxor or Aswan can give you time to see what was not included in the cruise package.
