Pamukkale is truly a very beautiful,natural and historical site with sparkling white castle-like cascades and can be considered as one of the most important highlights of Turkey. The site is named in Turkish as "Pamukkale", that means "cotton castle". The white calcareous castles are formed by thermal springs containing limestone, creating the formation of stalactites, potholes and cataracts. Water in the terraces are the sediments of the springs having calcium compounds. The waters runs off the plateau's by depositing calcium. The marvelous landscape of Pamukkale has been created by this gradual formation, leaving a cotton-like image.
