About the location (from Wiki):
Köprülü Canyon is a canyon and a National Park in the Province of Antalya, Turkey. Covering an area of 366 km2 (141 sq mi), it was established as a national park by the Ministry of Forest on December 12, 1973. The canyon is 400 m (1,300 ft) deep in some places and stretches for 14 km (8.7 mi) along the Köprü River. At the resting area, there are fish restaurants offering delicious food especially fresh trout. The Roman Oluklu Bridge (Olukluköprü) over the canyon and the Bugrum Bridge over the Kocadere stream were engineering feats of their time. Northeast of Antalya on the Side road take the turn off for Tasagil and Beskonak, for the beautiful circular, scenic route that leads to the Koprulu Canyon National Park. The road criss-crosses over the clear, flowing water of the mountain river and passes through virgin forests and over rippling waterfalls.
