Private Bosphorus tours will take you to Bosphorus – the famously beautiful stretch of water, 32 km long with the maximum of 3.700 m width, plays central role in the history of Byzantium, later Constantinople and today’s Istanbul. The Bosphorus, with the Golden Horn (an inlet of the Strait) and Maiden’s Tower (Kiz Kulesi) at its southern entrance, has a definite personality. The Bosphorus is the Persona of Istanbul, a beautiful female, who despite the disrespect that men show to that pretty lady, the Strait stays charming, inspirational and full of surprises.
That beauty, though, should not the least distract you. Bosphorus – the stretch of water that connects two seas, the Black Sea and the Sea of Marmara and is the natural boundary between two continents, Asia and Europe (thus making Istanbul the only city in the world lying on two continents), can be really dangerous. For its rocks and deceiving currents (on the surface, the Bosphorus flows like a river from the Black Sea to the Marmara but there is another current, below the surface, which flows in the opposite direction), the Bosphorus is a real threat for the passing ships, the big ferry traffic and all the small fishing boats and those taking tourists on a journey along the Bosphorus.
