Pamukkale, also known as “Cotton Castle,” is a UNESCO World Heritage Site located in the Denizli province of Turkey. The site is famous for its naturally formed terraces of white mineral-rich thermal water pools and is a must-see destination for any traveler visiting Turkey.

The terraces were formed over thousands of years as hot mineral-rich water from the nearby Hierapolis thermal springs flowed over the limestone and cooled, depositing minerals and creating the unique white terraces. Visitors can walk along the terraces and take a dip in the warm, therapeutic waters.

In addition to the terraces, the ancient city of Hierapolis is also located on the site. The city was founded by the Greeks in the 2nd century BC and was later conquered by the Romans. Visitors can explore the ancient ruins, including the Roman theater, necropolis, and the Apollo Temple.
