Köprülü Canyon has two different depths: the walls of the 14 km rafting gorge rise up to about 100 m (Ministry of Culture and Tourism), while the famous 300–400 m cliffs belong to the Tazı Canyon viewpoint area inside the same national park (Kültür Portalı) — most tour websites merge the two figures into one wrong number.

The Ministry of Culture and Tourism describes the canyon that rafters actually travel: the Köprüçay River forms a valley between the villages of Bolasan and Beşkonak, with canyon walls "as high as 100 m", and at 14 km it is the longest canyon in Türkiye. This is the gorge of the commercial rafting course, which begins about 100 m below the Roman Oluk Bridge, where the water is calm (nationalparksofturkey.com).
The Kültür Portalı — the same ministry's culture portal — describes the second place: Tazı Canyon, inside the national park boundaries at Beşkonak (Manavgat, Antalya), is about 4 km long with steep rock walls 300–400 m high, carved over millions of years by the erosion of the very same Köprüçay River. Its alternative name is "Bilgelik Vadisi" — Wisdom Valley.
The vertigo-inducing cliff-edge photos you see under "Köprülü Canyon" are taken at the Tazı Canyon viewpoint. Officially, there is no artificial or glass viewing platform there: the "viewpoint" is natural rock flats at the cliff edge (Kültür Portalı). The day-use area — gate, kiosk, photography concession — is formally managed under a DKMP 6th Regional Directorate tender (tarimorman.gov.tr), so the site is a regulated part of the park, not a wild overlook.
Secondary travel sites routinely claim the canyon "reaches a maximum height of 400 m" — and some go further, describing "gorge walls 400 m deep" above the rafting river. The ministry's own figure for the rafting gorge is up to about 100 m (ktb.gov.tr); the 300–400 m figure officially belongs to the Tazı viewpoint cliffs (Kültür Portalı). One national park, two locations, two very different numbers — and merging them produces the "400 m rafting canyon" that never existed.
The practical version: from a raft you look up at walls of up to about 100 m; from the Tazı viewpoint you look down 300–400 m into the gorge the Köprüçay has cut. Both experiences sit inside the same 47,473-hectare national park (DKMP national parks list).
While "400 m deep" is misplaced, Köprülü Canyon holds an official national record anyway: at 14 km it is the longest canyon in Türkiye (Ministry of Culture and Tourism). Rafting on the Köprüçay is an officially listed park activity (DKMP), and by industry consensus the course is mostly Grade II with occasional Grade III sections (Nomado Travel) — which is precisely why a gorge with 100 m walls, not 400 m ones, is where beginners raft.
Up to about 100 m, according to Türkiye's Ministry of Culture and Tourism. The gorge runs 14 km between the villages of Bolasan and Beşkonak — officially the longest canyon in Türkiye — and its walls rise directly above the Köprüçay River that rafters descend.
Not the rafting gorge. The 300–400 m figure officially describes the cliff walls of Tazı Canyon, a roughly 4 km section with a famous viewpoint inside the same national park (Kültür Portalı). Ministry sources put the rafting gorge walls at up to about 100 m.
Tazı Canyon is a roughly 4 km canyon inside Köprülü Canyon National Park at Beşkonak, with steep rock walls 300–400 m high, carved by the Köprüçay River. Its alternative name is Bilgelik Vadisi (Wisdom Valley). The viewpoint is natural rock flats — there is no glass platform.
The commercial rafting course runs the gorge whose walls reach about 100 m, starting roughly 100 m below the Roman Oluk Bridge where the river is calm. The 300–400 m Tazı cliffs are experienced from the natural viewpoint at the cliff edge, not from the raft.
