You start before dawn in Side, the coast still cooling from the night. A convoy of open-top buggies threads a switchback road out of town and climbs into the lower flanks of the Taurus Mountains; dust kicks up behind the machines like a trailing shadow. After a short village pass where minarets puncture the skyline, the canyon opens—sheer limestone walls dropping into the cold, fast channel of the Köprüçay River. The water dares you forward; instructors translate that dare into a controlled, splash‑filled route through Class II–III rapids.
