Southern Egypt, also known as Upper Egypt, is most famous for the scores of majestic ancient temples that still line the shores of the Nile River for hundreds of miles. Of all the towns and villages in this region, Aswan is the largest in the far south of Egypt and a favorite base from which travelers have set out to visit and explore these ruins for thousands of years. And of all of the temple ruins reachable from Aswan, Abu Simbel is by far the largest and most famous of them all.
