Cilicia lay at the eastern end of the Mediterranean coast, just north of Cyprus. It was separated from the Anatolian Plateau to the north and west by the Taurus Mountains, connected only by a narrow pass, the Cilician Gates. To the west lay Pamphylia, to the east the Amanus Mountains separated it from Syria. In ancient times Cilicia was naturally divided into two areas, Cilicia Trachaea (Κιλικία Τραχεία; Rugged or Rough Cilicia), a mountainous area in the west and Cilicia Pedias (Κιλικία Πεδιάς; Flat Cilicia, also Kilikia Leia or Smooth Cilicia), the flat plains to the east divided by the River Lamus, now called Limonlu Çayı. A major east-west trading route passed through it exiting through the Cilician Gates.
