There are natural springs found all over the world but few can match the size and spectacle of Pamukkale in Turkey. Over the years the deposits from the carbonate mineral springs have formed a white terrace of pools, which has led to the site being given the name ‘cotton castle.’ The ‘castle’ can be seen from miles around and is 2.7km (8,860ft) long, 600m (1,970ft) wide and 160m (525ft) high. People have bathed in the hot springs of Pamukkale for thousands of years and the waters are believed to have incredible healing properties. The area has 17 hot water springs in total and is one of Turkey’s biggest tourist attractions. The photos below show just why so many people are left stunned by this incredible natural phenomenon.
