Pamukkale

Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli Province in southwestern Turkey. The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water. It is located in Turkey's Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.

Dripping slowly down the vast mountainside, mineral-rich waters foam and collect in terraces, spilling over cascades of stalactites into milky pools below.

Aside from a small footpath running up the mountain face, the terraces are all currently off-limits, having suffered erosion and water pollution at the feet of tourists. While it is not open for bathing, the site is still worth a visit. Although many travelers...
