The Cilician Gates or Gülek Pass is a pass through the Taurus Mountains connecting the low plains of Cilicia to the Anatolian Plateau, by way of the narrow gorge of the Gökoluk River. Its highest elevation is about 1000m.

The Cilician Gates have been a major commercial and military artery for millennia. In the early 20th century, a narrow-gauge railway was built through them, and today, the Tarsus-Ankara Highway (E90, O-21) passes through them.
