Over the course of history, the Bosphorus has seen quite a lot: various conquerors and even both world wars. Today the channel which unites the Sea of Marmara and the Black Sea, as well as divides the land into the Asian and European continents, is mainly a commercial waterway for numerous cargo ships. The best way to discover the treacherous waters of the legendary Borphorus is via cruises that run in the summer. Various operators offer different tours depending on time and budget so you may choose one that fits your schedule. The usual running time is from April to October. However, Sunset Cruises are available only between early June and mid-September.
