Stunning photos of steaming hot springs in places like Iceland, Italy, and Turkey litter social media feeds. But you don’t need a passport or even a plane ticket to find geothermal pools. There are (literal) hot spots throughout the U.S. that’ve capitalized on pools heated by volcanic bedrock.

Spa resorts like Ojo Caliente Mineral Springs Resort & Spa in New Mexico, the restored ghost town of Dunton Hot Springs Resort in Colorado, and the former gold miner’s resort at Chena Hot Springs in Alaska offer that natural experience with all kinds of luxury amenities.

And if you’re the kind of traveler who prefers to work for your rewards, hot springs closer to home can be a one-two punch of adventure: the journey getting to a remote location and the joy of taking a dip in what’s essentially nature’s spa.
