One of our days in Istanbul was taken with a boat tour of the Bosphorus. I would never have imagined the delightful view along its banks where Europe truly does meet Asia.
The European side has all the mosques and palaces of the Istanbul where we stayed which I thought was beyond spectacular. But somehow it's the much more subdued Asian side that really delighted me. The entire city, with its endless shoreline is staggeringly beautiful.
It was a hot, hot day (it was around 40C (100F) every day we were there) but, as long as you stayed in shade, it was much cooler on the water. I was impressed with the cleaniness of the water of the strait. A population of 14 million and they maintain water clean enough for swimming.
With that many inhabitants it's not surprising that every inch of space is well utilised. The bridge across the Golden Horn between Beyoglu and Fatih is lined with fishermen, cars, and fish restaurants. The cars ride across the top where the fishermen stand and try their luck with very long lines and poles. Staircases lead down to a lower level closer to the water and lined with restaurants.
