Kadiköy, on the Asian shore of the Bosphorus just south of Haydarpasa, was known in Byzantine times as Chalcedon.
Today it's a bustling commercial and transportation center, and residential district of the megalopolis of Istanbul.
Most visitors pass through Kadiköy on their way to somewhere else, usually via the Kadiköy ferry docks just south of Haydarpasa Station across a cove.
From Kadiköy, ferries cross the Bosphorus regularly to Karaköy (Galata) and Eminönü at the mouth of the Golden Horn. Some ferries stop at Haydarpasa Station on the trip to or from Kadiköy.
The voyage is among Istanbul's greatest value-for-money pleasures: a 40-minute intercontinental cruise for less than YTL2!
There are both the traditional ferries operated by IDO, and the smaller private ferries operated by the TurYol cooperative. The docks are a few hundred meters apart.
Another landmark in Kadiköy is the Kozyatagi Business Center, about 6 km east of the Kadiköy ferry docks. From here, Havas airport buses travel to Sabiha Gökçen Airport, farther to the east.
