This place is the site of a unique natural phenomenon, and it is very close to the important archaeological zone of Hierapolis. The name Pamukkale means Castle of Cotton and this is particularly apt in describing one of the most extraordinary landscapes to be found in nature. Here, in a landscape fascinating in its own right, the action of various mineral springs, which contain calcium oxides, has left fantastic concretions on the travertine structures. The resulting effect is spectacular: these mineral-rich waters have dripped down over a series of terraced levels designing bizarre solidified cascades, dazzling in their radiance and changing their color according to how the sunlight strikes them. From a distance this whitish mass stands in evident contrast with the color of the surrounding uplands and brings to mind enormous stretches of cotton. On approaching this incredible succession of terraces, one discovers the existence of basins full of mineral water which flow into other natural basins below, and are the source of stupendous mineral conglomerations in the form of fantastic stalactites, some times of considerable size and resembling organ pipes. The continuous dynamics of erosion and transformation of the natural landscape has resulted in an ambience unequalled elsewhere and which constitutes one of the most unique phenomena to be found in nature. Hordes of wonderstruck tourists swarm daily through this fabulous lunar landscape. The excellent curative properties of the waters, known from ancient times in the neighboring Hierapolis, have permitted the construction in modern times of spas, generally annexed to the hotels in the area. The entire territory of Parnukkale is at the center of particular attention on the part of the competent authorities, who intend to safeguard the integrity and respect of this truly unique territory.
