Antalya, the largest city on Turkey’s south coast, has gained popularity in recent years as a resort region drawing more than 12 million visitors a year. Most stay at vast beachfront hotels and filter into the city in smaller numbers, so when you disembark, you won’t feel overwhelmed by crowds. It's easy to enjoy a day exploring the walled historic center on foot and climbing the surrounding hills for views of the bay. More ambitious is an easily arranged daytrip to a cluster of some of the finest ruins in the ancient world: Aspendos, Perge, and Side.
