Pamukkale is the site of the world's most unique and arguably most beautiful hot springs in the world making it a major travel destination. Which makes it an obvious choice to be a UNESCO World Heritage Site. Located far from Istanbul in southwestern Turkey Denizli Province. These ancient hot springs have been used for thousands of years powered by volcanos. Pamukkale's most distinct feature is how it looks like there's a nice coat of white snow over the site.
