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 millions of visitors who never see a beach. Turkey is the global leader in hair transplant procedures, performing more than 150,000 a year at a fraction of what the same operation costs in the United Kingdom or Germany.
