With a name that literally translates to “cotton castle,” Pamukkale is unreal and dramatic, with billowing white structures that look just like its name. But these are not actually cotton. These are thermal pools naturally formed from travertine, and filled with warm turquoise water. One of the most striking sights in western Anatolia, Pamukkale is located not far from the city of Denizil but feels worlds away, existing in its own magical realm of white. It’s a UNESCO World Heritage Site, and while most of the natural delicate travertine structures are visible but not accessible, there are still plenty of regulated travertine formations that can be walked upon and waded through barefoot, in any season.
