East of Adalia is the Cestrus, and beyond that again the Eurymedon, both of which were considerable streams, navigable in antiquity for some little distance from the sea.
The principal passes across the range are those over which Roman or Byzantine roads ran: - (i) from Laodicea to Adalia (Attalia), by way of the Khonas pass and the valley of the Istanoz Chai; (2) from Apamea or from Pisidian Antioch to Adalia, by Isbarta and Sagalassus; (3) from Laranda, by Coropissus and the upper valley of the southern Calycadnus, to Germanicopolis and thence to Anemourium or Kelenderis; (4) from Laranda, by the lower Calycadnus, to Claudiopolis and thence to Kelenderis or Seleucia; (5) from Iconium or Caesarea Mazaca, through the Cilician Gates (Gulek Boghaz, 3300 ft.) to Tarsus; (6) from Caesarea to the valley of the Sarus and thence to Flaviopolis on the Cilician Plain; (7) from Caesarea over Anti-Taurus by the Kuru Chai to Cocysus (Geuksun) and thence to Germanicia (Marash).
