Pamukkale, meaning literally in Turkish is ” Cotton Castle ” is one of the most important monuments that the nature of Turkey has to offer. It consists of a series of limestone terraces formed by the action of the hot springs that create a waterfall. The water contains a high concentration of carbonic acid and lime, which emerges as the particles settle and form these unique terraces, and falls as it flows downhill form stalactites, waterfalls and basins. There are only a handful of these strange formations around the planet, and you have to see to believe. The contrast with the rest of the landscape is breathtaking.
