What the Green Canyon in Turkey is, and what it is not
The Green Canyon is a reservoir: fresh water, held in place by the Oymapınar Dam near Manavgat, in the hills behind the coastal plain. Nothing about it is Mediterranean. The water is not salty, the shore is not sand, and there is no horizon — the view ends where the cliffs on the far side rise out of the water.
The name is what misleads people, and it misleads them in both directions. Some readers expect a dry gorge with a river at the bottom, of the kind you walk through; others assume a sheltered arm of the sea. It is neither. It is a long body of still water lying between steep, wooded walls, and the colour that gives it its name is the one visible fact everybody agrees on: a green deep enough that in photographs it is regularly mistaken for a filter.
The place, described rather than sold
Pine grows on the cliffs on both sides and comes down almost to the water, so the smell on a warm afternoon is resin rather than salt. Sound behaves differently too. There is no surf here and no wind fetch to speak of, so a boat engine and birds are most of what you hear, and the surface holds the reflection of the far wall instead of breaking it up.
The shoreline is not a beach. Where the boat stops it stops in coves — sheltered pockets along the cliffs where the captain can anchor — and guests go into the water straight off the deck rather than wading in from sand. The water is cool. That is the word our own record uses, and it is the honest one: after a week of hotel pool and Mediterranean shallows, expect the first few seconds to be a shock rather than a welcome, in the way a lake in the hills usually is.
Why an inland lake sits on a list of boat trips sold from a seaside resort
The reason is geography, and it is the same reason that shapes every boat day we sell. Belek has no boat harbour of its own in our records. Every day on the water therefore begins in a vehicle: the galleon day drives to Side Harbour and boards there, and the Green Canyon day drives inland to the reservoir instead. Once you accept that a boat day from Belek always starts with a drive, the choice of destination stops being strange and becomes an actual choice.
So the reservoir is not a consolation prize for a resort without a port. It is a genuinely different kind of day on the water, sold from the same hotels and collected from the same doorways, and what it puts in front of you is water calmer, greener and cooler than the sea in August.
How you get there from Belek
A driver collects you from your hotel in an air-conditioned vehicle and takes you inland towards Manavgat and the Oymapınar reservoir, where the cruise begins, and the same driver brings you back at the end. Door to door, the day runs to about eight hours, and a good part of that is the drive each way — which is worth knowing before you book, because it is scenery rather than dead time and it is also the reason this day is longer than a morning excursion.
There is a guide with you and the boat insurance is included, as is lunch on board. Drinks are not included, and neither are the optional extras sold on the day. Beyond that, the day is deliberately unstructured: free time on the open deck, several stops, and a lunch served while the boat is somewhere quiet.
What we will not tell you about this water
There are numbers you will find on other websites that you will not find here. We do not publish how high the dam is, how large or how deep the reservoir is, or what temperature the water reaches in any month, because none of that is recorded anywhere in our own material and we would only be repeating figures we cannot stand behind.
What we can say is what our record says: fresh water, deep green, cool, held back by the Oymapınar Dam, with cliffs of pine on both sides and coves calm enough to anchor in. If you want a specific figure for a school project, a search engine will give you one. If you want to know what the day feels like, the description above is the whole of what we actually know.
When it runs, and what a booking commits you to
The Green Canyon day runs on every day of the week, which sets it apart from the Manavgat market and river day — that one departs on Mondays and Thursdays only, because it is built around the market. If your holiday has one free day and it happens to be a Wednesday, the reservoir is available and the market is not.
As with everything sold here, the reservation itself takes no card and no deposit, and free cancellation runs until 24 hours before departure. Infants travel free and children pay a reduced fare; the price guide carries the figures, and this page deliberately does not, because a page about a place should not go stale the day the tariff changes.
