Pamukkale is a tourist attraction. It is recognized as a World Heritage Sites together with Hierapolis. A few other places in the world resemble it, including the Mammoth Hot Springs in the USA and Huanglong in Sichuan Province of China (another UNESCO World Heritage Site). Hierapolis-Pamukkale was made a World Heritage Site in 1988.
Before the World Heritage designation, Pamukkale went unprotected for decades in the late 20th century and hotels were built on top of the site, destroying parts of the remains of Hierapolis. Hot water from the springs was taken to fill the hotel pools and the waste water was spilled over the monument itself, turning it brownish. A tarmac road ramp was built into the main part. People walked around with shoes, washed themselves with soap and shampoo in the pools and rode bikes and motorbikes up and down the slopes.
By the time UNESCO turned its attention to Pamukkale, the site was losing its attraction. Officials made attempts to restore the site. The hotels were demolished, and the road ramp was covered with artificial pools which today are accessible to bare-footed tourists, unlike most other parts of the site. A small trench was carved along the outside of the ramp to collect the water and prevent it from spilling. The brownish parts have been left to be bleached by the sun without being covered by water to diminish the problem. Therefore many pools are empty. Others parts are covered with water for an hour or two, on a rotating schedule.
The underground volcanic activity which causes the hot springs also forced carbon dioxide into a cave. The result was called the Plutonium meaning place of the god, Pluto. Tadpoles can be found in the pools. vikipedia
