Lovers of historical sites will adore Aspendos, an ancient Greco-roman city containing one of the best preserved ancient theaters in Turkey.
My suggestion:
It's best to spend the day there and picnic on higher ground at midday, surrounded by natural countryside and with breathtaking views out over the site.
Summary:
Staying in Antalya meant I was located quite close to the magnificent site known as Aspendos. I advise going there on a day trip and returning to spend the night in Antalya in the evening. Aspendos is an absolutely exceptional site: an ancient Greco-Roman city composed of very beautiful, and very numerous, architectural remnants and ruins – aqueduct, theater, the remains of a basilica, etc. – located out in the middle of the countryside.
