Adana is in Mediterranean Turkey. Lying a fair distance away from the Mediterranean coast, in the centre of huge Cilician Plains and on the banks of Seyhan River, Adana is one of the most populated cities in Turkey with a population of over 1.5 million. It's not much known as a tourism destination, though, especially when compared with its southern and western neighbours. However, that being said there are a number of sites of interest in the surrounding countryside.
