Turkey

Turkey earns its spot on this list less through a single headline arrivals number and more through range: the Turkish Riviera offers genuine Mediterranean luxury at a noticeable discount to comparable resorts in Greece or Italy, while a separate industry entirely - medical tourism - adds hundreds of thousands of visitors who never see a beach. Turkey has built a reputation as one of the world's biggest hubs for hair transplant procedures, performed at a fraction of what the same operation costs in the United Kingdom or Germany.
