All the streams of the region aim at finding their way into the Mediterranean and they pour down the slopes of the Taurus, sometimes overland sometimes underground and reaching their destination, result in lovely waterfalls, of which there are more than twenty. The loveliest of these are the Duden Falls, 15 km. north of Antalya, about 1 hour boat trip in Kaleiçi (old city) harbor,  Karpuzkaldiran waterfall is the highest as it is approx. 30 meters high and the water gushes down onto the massive rocks with great force.
