Bosphorus is at the critique point of two big love stories; one is sad. The strait connects Black Sea to Marmarian Sea and divides Asia from Europe. At the beginning of winter time every year, Black sea sends hundreds of dolphins to Marmarian Sea to show his affection and love. Enough romance? Here is the greatest news; you may be one of the lucky ones to watch them! When winter starts to be felt at the Northern Hemisphere, Black Sea gets cooler and dolphins use this way to go down to warmer waters of Marmarian and Mediterranean Sea. Even Bosphorus has very heavy traffic of ferries, cruises and ships, if you come to the city at the right time, you may have a chance to witness that beauty.
