There is a ferry company that sails every day at 09.30 to both Alanya and Tassucu. The latter is better for the short trip via Mersin to Adana. Consult the website, though there is no English translation (resort to google translator)!
the external parts of Adana may be attractive with the Kozan lake, Aladaglar national park, the Taurus Mountains, Ceyhan, the Snake Castle and Misis.
to arrive these locations, a traveler must first go to the Yuregir Otogar buy a dolmush or bus, and then from this terminal; you can find a bus to your destination easily.
the traffic is not that terrific, but it may still be hard to drive -or even walk- in the city center since all the busses and minibusses track the same road.
the minibusses are called "dolmush" in local language, and they (both dolmushes and busses) cost 1 TL for each person. they can take you anywhere in the city, but to communicate with the driver may be difficult :)
Beside airways and Coaches like Varan and Ulusoy you can have a joyfull railway trip to Adana from many destinations like Istanbul Ankara and Izmir. Ewery day theres trains between major towns to Adana.
Adana has an effective city bus system ABOI buses are all climatized and you can get ewerywhere.There is private OHO midibus service also.Belkart named multipass cards are very usefull.
To get Adana beside luxury Coach services you can use the railway also there are railbuses and operating around districts frequently........
