Pamukkale, or Cotton Castle, is famous for its limestone deposits formed on the slope of Cokelez Mountain. The water flowing out of the hot springs, cooling on the surface, precipitates calcium carbonate, the sediments of which create fanciful thresholds, terraces and pools. The view is amazing, and walking along the picturesque travertines we had the impression of treading on ice. The entire area has been included in the Unesco Natural Heritage List. Water also has healing properties, which were appreciated in antiquity when the spa of Hierapolis was built nearby.
