With its surreal white terraces and opalescent blue pools, Pamukkale's striking thermal springs have drawn attention since ancient times. Fly from Istanbul to experience this incredible UNESCO World Heritage Site firsthand, and visit the ruins of the Greco-Roman city of Hierapolis on this day trip.

You're picked up at your hotel before sunrise to catch an early flight toward the coast. Once you touch down, hop on a shuttle for the ride through the countryside to Pamukkale, whose name means “cotton castle” in Turkish. Admire the towering, palatial structure formed by the mineral-rich waters, which have been pooling into stepped platforms and terraced springs for thousands of years.

Take a dip in the warm and soothing waters, which range in temperature from 95–212 degrees Fahrenheit (35–100 C), and snap photos of the breathtaking formations that shape the springs. From there, head to the top of the plateau to visit the ancient spa town of Hierapolis. Roam among the remains of the great baths, and visit the archaeological museum to peek at objects recovered from the area before heading back to the airport for your return flight to Istanbul.
