Bosphorus is the strait in Istanbul that divides Asia from Europe. A ferry ride along the Bosphorus is an unforgettable experience. It is touristic and so local.
Old wooden houses, mansions and palaces and the two bridges that connect to continents. Charming seaside districts, once fisherman's villages and remarkable pieces of Ottoman architecture all spread along. The current ferry schedule is here. There also some other companies running, starting mostly from Eminönü.
