It is located in Varsak Neighborhood, within the boundaries of Kepez District. Düden Waterfall is also mentioned in various sources as İskender Waterfall and Yukarı Düden Waterfall. At the same time, there are those who call Düdenbaşı Waterfall among the people.
On the 28th kilometer of the old Antalya-Burdur road, two large karst springs named Pınarbaşı emerge on the 30th kilometer of Kırkgözler. These two rivers, with plenty of water, merge after a short flow and disappear in the subalpine sinkhole. After the water disappeared in the subalpine sinkhole about 14 kilometers underground, it exits from one end of the Varsak Collapse, after a very short flow, it sinks again from the other end of the collapse.
The water lost in Varsak comes to the surface in Düdenbaşı after about two kilometers of underground flow. Even on days when no water flows from the surface, at least 10 cubic meters of water will rise to the surface from under the Düdenbaşı Waterfall. The maximum flow rate of this water is 94 cubic meters and the average is 15-16 cubic meters per second.
The water flowing from Düdenbaşı by making a waterfall from above is the water coming from the Kepez hydroelectric power plant. After Düdenbaşı, Düden Stream, which is divided into two main canals in the sheep regulator, is poured into the Mediterranean by making a waterfall from a travertine threshold at the height of 40 meters east of Antalya after 9 kilometers.
