02Hierapolis-Pamukkale, Turkey

The mineral-rich waters from Cürüksu are responsible for creating the terraced basins, solidified waterfalls, and mineral landscapes of the spectacle that is Pamukkale. Affectionately known as the "Cotton Castle'', the solidified white calcium deposits along with the structures of the Greco-Roman ruins of the city of Hierapolis, make it the country's most popular tourist destination.
