İzmir, the third largest city in Turkey, sits on the Aegean Sea. In 4,000 years of history, it's seen its share of occupants—from Greek and Persian to Roman and Ottoman—and has the cultural heritage to show for it. A thriving metropolis, İzmir has some of the liveliest bazaars in the region, where you can find anything from cherries to handwoven rugs, and it makes for an awesome jumping off point for day trips to smaller towns like Çeşme.
