One of the world's most fascinating natural landmarks is located in south west Turkey in Denizli Province.  Emerging from the earth in the middle of nowhere an incredible, pure white natural rock structure sits majestically like a castle made from cotton wool. Indeed its Turkish name, Pamukkale means literally this. Today it attracts millions of tourists from across the globe that come to bask in its warm, natural mineral springs, which cascade down the white limestone rocks.
