I visited this WHS in June 2014. Although touristy, I really enjoyed my visit and spent a half a day exploring different point of views, buildings, remains and museums included in the 12e entrance fee. Apart from the Parthenon and the Erechtheion with the Porch of Caryatids, I enjoyed visiting the Odeon on the South slope and the surrounding hills, each with a spectacular panoramic view of Athens. I particularly enjoyed visiting the Ancient Agora which is pretty much intact and well worth a visit.
