Pamukkale, which means “Cotton Castle” in Turkish, is a natural site located in southwestern Turkey, near the city of Denizli. It is known for its stunning white terraces of travertine, a type of limestone deposited by hot springs.

The hot springs have been flowing for thousands of years, leaving behind layers of white calcium carbonate that have built up over time to form the terraced pools. The water in the pools is rich in minerals, which are said to have healing properties.

In addition to the terraces, Pamukkale also has ancient ruins of the city of Hierapolis, which was founded in the 2nd century BC. Visitors can explore the remains of the city, including the Roman amphitheater, the ancient baths, and the Temple of Apollo.

Pamukkale is a popular tourist destination and is listed as a UNESCO World Heritage Site. Visitors are allowed to walk on the terraces and swim in some of the pools, although there are restrictions in place to protect the site from damage.
