One cannot visit Athens without climbing the Acropolis, or so Im told. We visited in January, when ticket prices are reduced and lines are non existent. Even though we are both out of shape, the hike wasnt exahusting. Bring a water bottle and visit the restroom before arriving.
Some tips: The acoropolis museum nearby houses most of the artifcats retrieved from the Acropolis, and should be visited as well. If you start in the museum, first stand in line in the Acropolis, buy your ticket, and then go to the Museum. This way you wont have to queue later, when the line will get longer. I recommend English speaking travellers use Rick Steves self guided audio tour (its free, google for it) as it provides a great 60 mins walk through history.
