Start with a trip to Kusadasi’s ancient showpiece, 2,000-year-old Ephesus, just a short drive from the city. This once-powerful Greek and Roman port boasts well-preserved streets and ruins, including the spectacular Library of Celsus and a theater where St. Paul once preached. Go with a guide—on either a shared group or private tour—to ensure you hear the story of the ruins and cover the highlights.

Alternatively, dedicate the morning to Kusadasi’s beaches and seas. Sunbathe on the town beach or Ladies’ Beach, or join a boat trip to swim and snorkel in bays inaccessible without a rental car. Another option is a visit the traditional hill village of Sirince to learn about rural Turkish life and sample local fruit wines.

If you didn’t take a morning-and-afternoon boat trip earlier, dive into Kusadasi’s outdoor adventures this afternoon. Join a Jeep safari to visit hidden canyons and coves, or open the throttle of an all-terrain vehicle to zoom over sand dunes. Other options include horseback treks through shady pine woods—a perfect way to get active while also staying cool. If you’re drawn to the sea, seize the chance to experience Kusadasi’s underwater world: check out the Aegean’s reefs and marine life on a private scuba diving package—tour options include an introductory taster for those new to the sport.

This evening, recover from the day’s exertions at a Turkish bath, which includes a sauna, a foam bath, and an aromatherapy massage. Choose from various bath experiences, some of which offer round-trip hotel transfers. Afterward, stroll by the beach and relax over dinner at one of Kusadasi’s many restaurants offering fish and typical Turkish dishes. If you’re in a party mood after dinner, make a beeline for the lively, packed Bar Street to hit its neon-lit clubs and watering holes.
