The Duden River is located within Antalya and is known primarily for its two waterfalls, which have become some of the city's most notable natural landmarks. Upper Duden is located in the Kepez district, a little away from central Antalya, while Lower Duden is found on the Lara coast, where the stream plunges from a rocky ledge directly into the Mediterranean Sea.

Duden is a karst river: it is fed by springs, and part of its water flows through underground channels. These features have made the river important not only as a natural site, but also as part of the city's water supply system. In the 20th century, the riverbed and the associated hydraulic structures were used in the development of Antalya's infrastructure.

For tourists, Duden is interesting because it makes it possible to see two very different sections of the same river. At the Upper Waterfall, you can get close to the stream and walk along paths in the park area, while at the Lower Waterfall, you can watch the water fall from the cliffs into the sea. Both places are suitable for a walk, a short stop while traveling around the city, and getting acquainted with the natural side of Antalya.

The Turkish name Karpuzkaldiran is associated with the Lower Waterfall and is usually translated as "watermelon lifter." According to local legend, watermelons were once floated downstream along the river, and over time this name became attached to the waterfall and the neighboring part of the city.
