List of Natural Hot Springs
10. Boquillas Hot Springs - Big Bend National Park, Texas
Located deep in the Chihuahuan Desert, the Boquillas Hot Springs offer a truly primitive soaking experience. These 105°F thermal waters pool directly on the banks of the mighty Rio Grande.
Visitors sit in an ancient rock foundation—the only remaining ruins of an old bathhouse—while gazing directly across the river into Mexico. It is a stunning, deeply isolated geographical experience that perfectly captures the wild spirit of Big Bend National Park.
9. Burgdorf Hot Springs - McCall, Idaho
For those seeking a pioneer aesthetic, Burgdorf Hot Springs in Idaho offers rustic, gravel-bottomed thermal pools surrounded by the dense Payette National Forest.
Operating completely off the grid with no cell service and very few amenities, Burgdorf provides a true escape from modern life. In the winter, this historic site is only accessible by snowmobile, adding a thrilling element of adventure to your soak.
8. Montezuma Hot Springs - Las Vegas, New Mexico
Located just outside the historic mountain town of Las Vegas, New Mexico, the Montezuma Hot Springs feature a unique cluster of natural stone and concrete pools.
Fed by scorching volcanic vents, the water cascades down a hillside, filling multiple pools of varying temperatures. Situated on the grounds of the United World College, these historic pools are freely accessible to the public, offering a raw and communal soaking experience.
7. Wild Willy's Hot Spring - Mammoth Lakes, California
Set in the shadow of the breathtaking Eastern Sierra mountains, Wild Willy's Hot Spring is an iconic California destination. Visitors must navigate an elevated wooden boardwalk through dense sagebrush to reach it.
The main draw is a stunning, naturally formed heart-shaped pool situated right in the middle of an active volcanic caldera. The dramatic mountain backdrop makes it one of the most photogenic primitive springs in the country.
6. Granite Hot Springs - Jackson, Wyoming
Tucked deep within the Gros Ventre Mountains, Granite Hot Springs offers a rugged, seasonal adventure. During the summer, it's accessible by a bumpy dirt road, but winter transforms the journey entirely.
When the snow falls, the hot springs can only be reached via a grueling but incredibly scenic dog sled ride, snowmobile trip, or cross-country ski trek. The reward is soaking in steaming 112°F water while surrounded by towering, snow-covered pine trees.
5. The Crater - Midway, Utah
The Crater in Utah is a geological marvel unlike any other hot spring on this list. It is a 65-foot-deep geothermal spring completely hidden inside a massive, 10,000-year-old limestone geothermal dome.
While it has been slightly developed to allow safe access, the interior remains wildly natural. The water is consistently warm enough to permit year-round scuba diving, making it the only warm-water scuba destination in the continental United States.
4. Spencer Hot Springs - Austin, Nevada
Located in the vast, silent expanse of the Nevada desert, Spencer Hot Springs is the epitome of primitive thermal bathing. There are no facilities, no staff, and no paved roads.
The springs consist of natural dug-out pools and repurposed cattle troughs maintained entirely by a dedicated community of local enthusiasts. It offers complete isolation, breathtaking views of the Toiyabe Range, and an unmatched sense of wild freedom.
3. Warm Springs Pools - Bath County, Virginia
Steeped in early American history, the Warm Springs Pools in Virginia offer a slightly different take on the natural hot spring experience.
The crystal-clear mineral baths bubble up naturally from the earth, but they are enclosed by stunning, preserved 19th-century octagonal wooden bathhouses. Bathing here feels like stepping back in time; you are soaking in the exact same pristine waters once enjoyed by Thomas Jefferson.
2. Chena Hot Springs - Fairbanks, Alaska
Chena Hot Springs in Alaska provides arguably the most atmospheric and surreal soaking experience on the planet.
Visitors can submerge themselves in soothing 106°F mineral water while the surrounding air plunges well below freezing—often causing the hair on your head to instantly turn to ice. If you time your visit right during the winter months, you can enjoy this thermal contrast while the Northern Lights dance across the sky above.
1. Iron Mountain Hot Springs - Glenwood Springs, Colorado
While slightly more developed than others on this list, Iron Mountain Hot Springs strikes the perfect balance between natural beauty and accessibility.
Instead of a massive, heavily chlorinated commercial pool, this destination offers 16 distinct, intimate geothermal pools terraced beautifully along the banks of the Colorado River. Each pool is maintained at a different temperature, allowing visitors to customize their soak while enjoying unobstructed views of the Rocky Mountains.
