Pamukkale is a natural wonder located in the southwestern part of Turkey, in the Denizli province. The name "Pamukkale" translates from Turkish as "Cotton Castle," and it is fully justified: the snow-white terraces of travertine resemble a castle made of cotton or fluff. These terraces were formed by thermal springs rich in calcium. Water flowing down the slopes of the mountains leaves mineral deposits, which over time turn into unique limestone formations. Pamukkale is included in the UNESCO World Heritage List and is one of the most visited tourist attractions in Turkey. Near the terraces, there are the ruins of the ancient city of Hierapolis, founded in the 2nd century BC. Here you can see the ancient theater, necropolis, and the Cleopatra's Pool—a thermal pool where you can swim among ancient columns.
