When hot water bubbles up through the surface of the earth, the resulting springs are some of the most amazing natural wonders you can encounter. For centuries, these mineral-rich waters have either gathered naturally into pools or have been channeled into man-made spas, both options providing therapeutic and medicinal benefits—and some good old-fashioned relaxation. And while some of these springs aren’t suitable for swimming, they’re still photogenic enough to get you hundreds of likes on Instagram. Here, 12 of the best hot springs around the world.
