Introduction to the sea of ​​clouds: When you climb to the top of Pamukkale, you will find that there is a sea of ​​clouds even at the bottom of this not-so-deep valley. This valley, which looks like a vast sea of ​​clouds, is forbidden to tourists because it is actually a strange swamp. The steaming light blue you see on the top of the mountain is not clouds, but a large amount of hot spring water containing calcium carbonate sinking to the bottom of the valley, forming a mud-like sediment. When the sun shines, it glows enamel-like peacock blue. The luster looks exactly like the blue clouds floating in the valley. This kind of landscape is extremely rare. Weather, sunshine, time, and luck are all indispensable.
