It is located in Varsak District, within the boundaries of Kepez District. Düden Waterfall is also referred to as Iskender Waterfall and Yukari Düden Waterfall in various sources. At the same time, there are those who call Düdenbaşı Waterfall among the people. On the 28th kilometer of the old Antalya-Burdur road, on the 30th kilometer of Kırkgözler, there are two large karstic springs called Pınarbaşı. These two rivers with abundant water merge after a short flow and disappear into the Whiskered Sinkhole. After the water lost in the Bıyıklı Sinkhole goes under the ground for 14 kilometers, it emerges from one end of the Varsak Depression, after a very short flow it sinks again from the other end of the depression. The water lost in Varsak rises to the earth in Düdenbaşı after two kilometers of underground flow.

Even on days when no water flows from the surface, at least 10 cubic meters of water rises to the surface per second under the Düdenbaşı Waterfall. The maximum flow rate of this water is 94 cubic meters and its average is 15-16 cubic meters per second. The water flowing by making a waterfall from above in Düdenbaşı is the water coming from the Kepez hydroelectric power plant. After Düdenbaşı, the Düden Stream, which divides into two main canals in the sheep regulator, pours into the Mediterranean after 9 kilometers from a 40-meter high travertine threshold in the east of Antalya.
