8. Pamukkale, Turkey
Pamukkale, or "Cotton Castle," is a series of white mineral-rich thermal spring terraces that cascade down the mountainside, creating an ethereal landscape that looks like a frozen waterfall of milk. The hot springs have been used for thousands of years, with their therapeutic properties attracting visitors long before modern tourism. The natural pools are filled with warm water, and the calcium deposits create an effect that looks like fluffy, white cotton, making it one of Turkey’s most surreal sights.
