Pamukkale Travertines
The unforgettable centrepiece of the day, the travertines of Pamukkale — "Cotton Castle" in Turkish — cascade down the hillside in a series of dazzling white terraces filled with warm, mineral-rich turquoise water. Formed over millennia by calcium-laden thermal springs, this natural wonder is unlike anywhere else on earth, and walking barefoot along the terraces, with the Anatolian plain stretching below, is a truly once-in-a-lifetime experience.
