6. Antalya.
This bustling Mediterranean hub has something for everyone.
The two main beaches outside of town are sun-sloth heaven in summer and attract holidaymakers from across Europe. While the old town area, snug right in the center of town, with its cobblestone alleyways rimmed by creaky Ottoman-era mansions, is a wonderful place to explore.
The Antalya Museum is renowned as one of the country's best, with an astonishing collection of Hellenistic and Roman marble statuary, and there are bags of attractions outside of town for travelers who want to use Antalya as a base.
In particular, Antalya is an easy base for day trips to some of Turkey's most famous Greco-Roman ruins, including Aspendos and Perge, which are just outside the city, and the town of Side, with its glut of ruins.
