Aphrodisias is a remarkable and vast site, which is mostly un-excavated. Its ruins are to be found amid the natural landscape, springing up from the greenery or half-buried in the dust, much as it would have been to the original team who discovered the city.
At the entrance/exit to the site is a superb museum that contains artefacts from Aphrodisias, displayed in a very clear manner. The reason for the excellence of the museum is that the site was excavated by a Turkish archaeologist — seemingly a rarity among the main Turkish sites — so the highlights have not been removed to the country of the archaeologist's origin. You will probably visit the museum on your way out of the site, having explored the huge city's ruins first.
