The rippling alabaster terrace of Pamukkale, or “Cotton Castle”, rises steeply from a low green valley to a dreamy mountain ridge in Anatolia. Renowned for its otherworldly landscape and shallow, milky-blue pools, Pamukkale gives visitors a sense of overwhelming awe and strange excitement at this natural wonder. The fading hours of daylight attract the biggest crowds, when the blank white canvas of calcium carbonate formations reflects the extraordinary prism of colors from the sky.
