World's Coolest Hot Springs
Art Directors & TRIP/Alamy
The Soak: Known as the Sacred Pool, this divine dip in southwestern Turkey lives up to its name: as you float in spring-fed water that’s a relatively refreshing 94°F, look up at a cerulean Aegean sky and down at 2,000-year-old Greek and Roman antiquities scattered on the pool’s floor.
The Scene: The eye candy here is a panorama of gleaming white terraces—Pamukkale means “Cotton Castle” in Turkish—created as flowing water deposited layers of calcium carbonate. Soaking in these natural pools is no longer allowed, but you can snap photos and then visit the nearby Roman city of Hierapolis.
When to Go: Year-round, but early fall is particularly lovely.
