There’s no better cure for what ails you than a long soak in a hot bath. And while “taking the waters” always feels great, some thermal pools earn bonus points for their gorgeous settings—historic architecture, say, a verdant jungle, or a snow-covered mountain valley. These 14 soaking spots are far from Jacuzzis: instead, they mix straight-from-the-ground healing waters with straight-out-of-your-dreams surroundings for a downright magical experience.
1. Alba Thermal Springs and Spa
Fingal (Melbourne), Australia
The region around Melbourne is one of the most exciting geothermal hot spots in the Southern Hemisphere. The 560-mile Great Victorian Bathing Trail, which opened in 2024, now connects such springs and day spas as Peninsula Hot Springs and Metung Hot Springs, with more coming to Phillip Island and 12 Apostles on the Great Ocean Road. Stop in at the stylish Alba Thermal Springs and Spa on the Mornington Peninsula, about 60 miles south of Melbourne’s central business district. The naturally heated sodium chloride bicarbonate spring water is sourced from 1,800 feet underground and is between 98.6 and 109 degrees Fahrenheit. (All temperatures cited in this story are Fahrenheit.) Once it’s pumped above ground, the water feeds a series of picturesque pools, including an herb-infused botanical pool, a salt pool that makes you feel weightless, and others surrounded by native bush plants or modernist concrete pavilions. Don’t miss the on-site restaurant Thyme, where dishes draw on the full bounty of Victoria. Tuck into house-made ocean trout gravlax, spanner crab with burnt butter, and an extensive list of local wines, beers, and spirits.

2. Terme di Saturnia
Saturnia, Italy
Etruscan and Roman legend holds that the Terme di Saturnia springs were created during a battle between Jupiter and Saturn, when Jupiter hurled his lightning bolts at Saturn but missed, instead striking the ground in what is now southern Tuscany, about two hours’ drive from Rome or Siena.
You have two options here: book a room or a day pass at upscale spa hotel Terme di Saturnia—which has four outdoor thermal pools and sunbeds and umbrellas for rent—or follow the locals upriver to the Cascate del Mulino (Mill Waterfalls), right next to an old mill and with views of the surrounding Tuscan landscape. Note that there is a slightly eggy smell from the sulfur. This not entirely pleasant odor led medieval visitors to believe that this area was the gate to hell, but that’s not keeping anyone away these days: The bath, which steams away at 99.5 degrees, is free and open 24 hours a day, with crowds at all times of day and night.
Take in the minerals of the natural spring waters at Castle Hot Springs, an oasis in the Sonoran Desert.

3. Castle Hot Springs
Morristown, Arizona
The legacy of Castle Hot Springs, about one hour north of Phoenix in a secluded valley of the Sonoran Desert, dates back to 1896, when it was first transformed into a wellness destination where travelers could experience the curative benefits of its healing waters. A fire in 1976 and another in 1996 brought operations to a halt. But Castle Hot Springs found new life in the 21st century when the luxury, all-inclusive resort reopened in 2019 following an extensive restoration. There are three hot springs: The highest (and closest to the source) is about 106 degrees. One tier down is a 96-degree pool, and a bit further along the canyon is the deepest pool, with a temperature of 86 degrees. The spring water also supplies the resort’s central swimming pool.

4. Pamukkale
Pamukkale, Türkiye
Pamukkale translates to “cotton palace” in Turkish, but with its dreamy hues of white and baby blue, we’re wondering if “cotton candy palace” wouldn’t be a better moniker. These hot springs, a 2.5-hour drive east of Izmir, boast an alien beauty that has drawn visitors since the 2nd century B.C.E., when the Romans built the nearby spa city of Hierapolis. Today, you can climb around the pearly travertine terraces at this UNESCO site and splash in the shallow pools (barefoot, to protect the delicate carbon deposits). At the top of the 8,860-foot-long slope of stepped pools are man-made baths fed by the same source, including the Cleopatra Antique Pools—a mineral-rich, Roman-built bath now filled with submerged columns from the city’s ruins.
At Dunton Hot Springs, guests stay in a collection of 14 uniquely decorated log cabins.

5. Dunton Hot Springs
Dolores, Colorado
Located in southwest Colorado’s highly mineralized San Juan Mountains, Dunton Hot Springs is a collection of 14 uniquely decorated log cabins from which resort guests can access the property’s 19th-century bathhouse and natural mineral springs. Against the cozy alpine backdrop, an hour and 45 minutes from Telluride, soak in 85- to 106-degree springs rich in iron, manganese, and calcium bicarbonate. Guests can go for a dip in the bathhouse, in the two outdoor pools, in the more natural setting at the source of the springs, or—if they book the Well House cabin—in their own private hot spring bath and cold plunge pool. You’ll have mountain and meadow views for days whichever cabin you choose.
Lake Hévíz welcomed its first bathhouses as early as the 1790s.

6. Lake Hévíz
Hévíz, Hungary
Yes, there is such a thing as a geothermal lake, and it’s just as incredible as you’d imagine. A two-hour drive southwest of Budapest (or three hours by train and bus), Lake Hévíz is one of the world’s largest swimmable thermal lakes. It’s a popular spot not only for relaxation at Spa Hévíz but also for rehabilitation at Szent András hospital, which specializes in treating rheumatological conditions. The lake is fed from both cold and hot underground springs, and the water fluctuates from about 73 to 77 degrees in the winter up to about 91 to 97 degrees in the summer. You can spend your days floating among the water lilies or sinking up to your thighs in the therapeutic peaty mud along the lake’s edges. Spa Hévíz opens the lake to visitors and retains its 18th-century charm throughout its modernized facilities, including indoor pools, hot tubs, and saunas.
Come for the hot springs, stay for the northern lights and the Aurora Ice Museum.

7. Chena Hot Springs
Fairbanks, Alaska
These thermal springs, located 60 miles outside of central Fairbanks, were discovered in 1905 by gold miners; six years later, a bathhouse and 12 small cabins were installed for visitors seeking a warm bath in waters rich in sulfate, chloride, and sodium bicarbonate. Since then, Chena Hot Springs has expanded to include the 40-room Moose Lodge (two queens per room), 32-room standard Fox Rooms (two double beds), and eight Bear Family Suites that sleep up to six—as well as rustic cabins, camping, and yurt accommodations. The property uses geothermal energy for heating and electricity and to keep its on-site Aurora Ice Museum cold year-round. This employee-owned establishment also offers massage services, an on-site restaurant, dogsled rides, and horseback riding, among other activities. The main draw is undoubtedly the chance to see the dancing northern lights from the warmth of the hot springs.
One of the best parts of the Myvátn Nature Baths: the scenic natural surroundings

8. Mývatn Nature Baths
Mývatn, Iceland
Thanks to its location near the international airport, the world-famous Blue Lagoon is one of Iceland’s top attractions, drawing more than 1 million visitors in some years. For a bit more adventure and breathing room, head to the Mývatn Nature Baths, which are in a designated nature reserve in northeast Iceland off the Diamond Circle. With the same milky blue water as the Blue Lagoon and a fraction of the crowd, these are the hot springs of your dreams, fed from a bore hole at a scorching 266 degrees before the water cools to between 96 and 104 degrees. There’s a high concentration of sulfur—not enough to smell strongly, just enough to be good for your respiratory system. The lagoon has a few small alcoves and underwater benches to enjoy, as well as a cold plunge, a smaller hot bath, and natural steam baths. But what takes the Mývatn Nature Baths from wonderful to the stuff of fantasy is the scenic view: The baths overlook a valley dotted with craters, volcanic rock formations, and, of course, the occasional Icelandic horse.
Think of Banjaran’s thermal steam cave as a natural sauna.

9. The Banjaran Hotsprings Retreat
Ipoh, Malaysia
The Banjaran Hotsprings Retreat in a nearly 23-acre valley is sheltered by rugged limestone karst towers and a tropical rainforest. It’s two hours outside of Kuala Lumpur, roughly halfway between the capital and Penang. Each of the 44 villas has garden views or is perched over the neighboring lazy river. The retreat is built around a large emerald geothermal pond, shaded by a canopy of jungle trees, and features dipping pools, a waterfall, and a complex of geothermal caves. While the caves’ pools are too hot to bathe in, one chamber functions as a natural sauna and the others as mystical, naturally warmed meditation rooms and lounges.
For a distinctly New Mexico take on hot springs, head to Ojo Caliente.

10. Ojo Caliente Mineral Springs and Spa Resort
Ojo Caliente, New Mexico
Whether you’re in New Mexico for skiing or a dose of Southwestern architecture, cuisine, and culture, the pools fed by natural spring water at Ojo Caliente Mineral Springs and Spa Resort offer a tonic retreat just an hour from Santa Fe. Here, at 6,000 feet, the geothermal waters range in temperature from 97 to 102 degrees, and there are eight pools. They include an iron pool, believed to aid the body’s immune system, a mud pool for purifying the skin, and cliffside pools for a dramatic setting. Guests can check into a Pueblo-style suite complete with a private soaking tub, the cottages, a room in the 1917 Historic Hotel, or even a vintage trailer. Ojo Caliente resort’s roots go back to 1868, when the bathhouse first opened.
The historic Takaragawa Onsen will celebrate its 70th birthday next year.

11. Takaragawa Onsen
Minakami, Japan
According to local myth, folk hero (and prince) Yamato Takeru no Mikoto once fell ill near modern-day Minakami and followed a white hawk to a nearby hot spring, where he was cured. About two hours by train from Nagano and three from Tokyo, the area is a popular hot spring destination today. In particular, Takaragawa Onsen is a jewel of an onsen hidden along the Takaraga River. The traditional, charming pinewood lodge was built in 1955 under the shade of cherry trees and later expanded. The spa boasts four large outdoor thermal pools and two indoor baths, plus what is believed to be the largest open-air bath in Japan. Despite the pools’ roomy capacities, Takaragawa’s remote riverside locations ensures it remains a tranquil destination.
Friedrichsbad is one of the historic spa complexes that earned Baden-Baden its UNESCO World Heritage designation in 2021.

12. Friedrichsbad
Baden-Baden, Germany
When Friedrichsbad opened in 1877, it was the most modern and luxurious bathhouse in the world. The complex was built in neo-Renaissance style, though inspired by Roman baths; you can see real, well-preserved Roman ruins below the complex at the Museum of Ancient Bathing Culture. These elegant hot spring baths have 19th-century shower fittings, hand-painted majolica tiling, and the magnificent domed poolroom. Visitors feel as if they’re melting away through time as they move along the spa’s 17 stations from warm showers to various saunas, thermal pools drawn from the famously curative hot spring water of Baden-Baden, and cold plunges. Mark Twain has been quoted as saying Friedrichsbad is a place where you lose track of time in 10 minutes and track of the world in 20.
The Aqua Dome, quite possibly the world’s most futuristic thermal pool complex, has 12 indoor and outdoor pools.

13. The Aqua Dome
Oberlängenfeld, Austria
If the Jetsons ever vacationed at a thermal spa, it would look exactly like the Aqua Dome Hotel, an hour southwest of Innsbruck. The waters that bubble beneath this part of the Tyrolean landscape have been known for their healing powers since the 16th century. These days, the 12 indoor and outdoor pools form what is quite possibly the world’s most futuristic thermal pool complex, with three raised pools with temperatures ranging from 93 to 97 degrees, a river basin with a gentle current, and two centerpiece thermal baths encased in an illuminated, faceted-glass cone. All that and a panoramic view of the surrounding Ötztal mountains create an out-of-this-world geothermal experience.
The waters at Tabacón are heated by the neighboring Arenal volcano.

14. Tabacón Thermal Resort and Spa
La Fortuna, Costa Rica
Tabacón Thermal Resort and Spa is a true jungle paradise, a series of stepped, naturally flowing waterfalls and river pools in the shadow of Arenal volcano in Costa Rica’s rugged northwest, three hours north of San Jose. While the water has a high mineral content, the sulfur content is (thankfully) low, keeping the area smelling as fresh as the surrounding tropical flowers. Tabacón is home to pools of different shapes and sizes, from large pools with waterfalls you can hide behind to smaller, more private pools; most dips range from 72 to 105 degrees, but there are also a few cold pools that provide an invigorating icy plunge.
