Very good view of the beginning of Bosporus. Right side is the Black Sea. In the front nice view of European side of Istanbul, Sarıyer. Most of the time very windy.
This is the coolest place!!!! Turia is not enough, because this is, well, the very outskirts of Istanbul... The view is wonderful on the Black Sea. I think it's the only tourist destination where you can have such a view...
If the cafes are open, then you can have a wonderful cup of coffee. But they don't work all year round.
There is a very inexpensive seafood restaurant near the marina with a polite Turkish host. He has never imposed anything on me, adequately.
It's a good, psychologically pleasant place, honestly
Ruins of an ancient Genoese fortress.
It offers a great view of the Black Sea. You can get from Istanbul by regular scheduled ferry from Eminenyu Marina in 2 hours (it makes several stops along the way). Spend a couple of hours on the spot and swim back. And all this for little money. You get your tickets at the ticket offices at the pier, not at the barkers.
