Built in the mid-13th century, when this area was part of the Armenian kingdom of Cilicia, Yılankale took its name from a serpent once entwined in the coat of arms above the entrance. From the car park there's a well-laid path for 100m then a rough trail. Reaching the castle's highest point requires a steep climb over the rocks, past gatehouse, cisterns and vaulted chambers. Standing high above the wheat fields, though, you'll feel on top of the world.
Yılankale is 38km east of Adana and just over 3km south of the D400 highway.
