A motor transport ferry that can also transport bicycles for the normal passenger price. The journey takes about 30 minutes from Yalova to Gebze. Very pleasant and comfortable. I recommend securing the bikes additionally. Sometimes the sea is rough.

The mosque is located in the center of the group of buildings and in a location overlooking Gebze. It was built by Çoban Mustafa Pasha in 1510. It is understood that the construction of the complex was planned long ago and was revealed through an anonymous work.

The best way to get started quickly to travel by bike. Danger. The bus companies sometimes cause problems when they see the large, fully loaded bicycles. They want unnecessary money from a rip-off. Keep Calm. Insist on your rights and, if necessary, call the company's customer hotline.
