Famous Thermal Baths and Hot Spring Pools

These photographs show the pools and bathhouses at some of the world's best-known thermal baths and hot springs, from Budapest's grand halls to an Alpine stone bath and a red walkway through a Chilean ravine. Each one draws on naturally warm or mineral spring water, and each is somewhere travelers can plan a soak around; captions note the water temperature where it is documented, plus any closure worth knowing about. Saunas and steam rooms are left out, and ancient baths appear only where people still bathe in them. The order runs roughly west to east across Europe, then to Turkey and Japan, then north to south through the Americas.
