I went to Bursa by bus, the easiest way. At a moment of the trip, the bus parked on a ferry to cross Marmara sea and arrive at Yalova, and then continued its way up to its final destination. While you are on the ferry, you can, off course, drink a cup of tea, but also walk around, enjoy the sea landscape, etc. On the way back, I felt more secured to walk around and discover the ferry life! I saw a bird ball, there were dozens of them, they flew with the wind and showed themselves when they wanted. On the corner of the boat, there were two birds, they were looking at the Istanbul coast which was appearing nearer and nearer. They had this comical expression on their face !
