Pyramids of Giza, Egypt

 If you've visited places like the Colosseum in Rome or the Acropolis in Athens, built over 2,000 years ago, you may think you have a good handle on ancient sites. But the Pyramids of Giza take ancient to a whole other level. These were built over 4,500 years ago. Tourists were coming to see these magnificent structures literally thousands of years ago.

Located just outside Cairo, the pyramids, which is also where you'll find the Sphinx, are easy to get to, and tours are easy to arrange. A sunset camel ride around the structures is a wonderful experience.
