Pamukkale is a natural area and at the same time a famous tourist attraction in southwestern Turkey, specifically in the Menderes river valley, in the province of Denizli, where a temperate climate is enjoyed most of the year. A true fantasy declared a World Heritage Site by UNESCO in 1988, partly the work of geology and partly the hand of man, and each year attracts millions of visitors. The tectonic movements that took place in the depression of the Menderes river basin fault not only caused frequent earthquakes, but also caused the appearance of numerous hot springs. It was these waters, with their high mineral content (chalk in particular) that created Pamukkale. This natural phenomenon produces thick white layers of limestone and travertine that cascade down the side of the mountain, giving the sensation of standing before a frozen waterfall. These formations also take on the appearance of crescent-shaped travertine terraces, containing a shallow layer of water, arranged in the upper third of the slope to form steps ranging from 1 to 6 meters in height, or stalactites that support and join these terraces.These natural pools in Pamukkale are known as the Cotton Castle, which is literally what its name means in Turkish. These ledges and white pools with crystalline waters that stand out in the form of relief, are the true protagonists of this place.
