5Pamukkale, Turkey

Pamukkale, which means “Cotton Castle” in Turkish, is a surreal natural wonder located in southwestern Turkey. The site features terraces of brilliant white travertine, formed by the deposition of calcium carbonate from the hot springs that flow down the mountainside. These terraces, filled with warm, mineral-rich waters, cascade down the slope like an otherworldly staircase. The ethereal beauty of Pamukkale, with its dazzling white terraces and azure pools, looks like something from another planet.
