Zamantı and Göksu join 80 km north of Adana to form Seyhan River.

[1] Through the Classical Antiquity until Byzantine times, the river was called Karmalas.

[2][3] Tracing a curvy course through the narrow valleys and cascades of the Taurus Mountains (called Aladağlar in this section), the river is one of the most favorite rafting spots in Turkey, particularly in its section around the town of Yahyalı, rated 3 in the international scale from 1 to 6 [1].

A 500 km2 area along the river basin corresponds to Aladağlar National Park, mostly covered in forests and extending within Yahyalı (Kayseri Province), Çamardı (Niğde Province) and Aladağ (Adana Province) districts.

A dozen peaks exceeding 3,000 meters also surround the river, making a prized destination among alpinists.
