The Acropolis
No visit to Athens is complete without the Acropolis. The Parthenon, Erechtheion, and Propylaea sit on a rocky hill that has defined the city for 2,500 years. Go early — the first entry of the day offers cooler temperatures and far fewer crowds. The views across Athens, all the way to the coast, are extraordinary. Combine your visit with the Acropolis Museum at the foot of the hill, which houses the original friezes and tells the full story of the site.
