A soak in mineral-rich water is one of travel’s simplest luxuries—whether you are easing into a wild river pool under palm trees, stepping into a Neo-Baroque bathhouse in the middle of a capital city, or rinsing off before a quiet onsen soak in Japan. Hot springs and thermal baths have a long history across cultures: Roman thermae, Japanese onsen towns, Māori geothermal traditions, and desert jeep stops where the water is as unexpected as the landscape.
The heated water that rises in geothermal areas often carries dissolved minerals. Many travelers find a warm soak relaxing—good for unwinding after a long trek or a cold day outdoors—and some spa and onsen traditions associate mineral water with skin comfort and recovery. For a calm overview of common wellness talking points around warm soaking (not medical advice), see this guide to hot tub health benefits. Always follow the facility’s posted guidance, and check with a doctor if you have health concerns before long or very hot soaks.
Whether you are planning a honeymoon spa day, a road-trip detour, or a full onsen pilgrimage, the goal is the same: warm water, a slower hour, and a landscape you will remember.
This roundup gathers 20 hot springs and thermal baths worldwide—wild pools, municipal baths, resort spas, and onsen towns—across the Americas, Europe, Asia, Oceania, and Africa. Several entries mix my own visits with practical notes; others draw on trusted travel writers whose tips I have rewritten into one editorial voice. Their names stay as sources below. Agree with the list? Tell me which soak you would add.

How to Choose the Right Hot Spring
Not every “hot spring” feels the same. Matching the type to your trip style saves disappointment (and awkward swimsuit moments).
Wild / free-flowing pools: river ledges, cliff tubs, desert pools. Minimal or no facilities; temperature can vary; Leave No Trace and day-use rules matter. Great for adventure travelers; less ideal if you want lockers and showers.
Municipal / historic baths: city thermal complexes (think Budapest) with multiple pools, saunas, and ticketed entry. Social, architectural, and easy to combine with sightseeing.
Resort / commercial spas: Blue Lagoon–style lagoons, Polynesian Spa, Banff Upper Hot Springs. Bookable amenities, clearer access, and often sell out in peak season—check the official site before you go.
Onsen (Japan) and similar bathhouse culture: rinse thoroughly before soaking; towels stay out of the water; many traditional baths are nude and gender-separated; some places restrict visible tattoos. When in doubt, follow JNTO / facility etiquette signs.
Quick etiquette & wellness reminders: hydrate; start with shorter soaks if you are new to high heat; avoid alcohol before long sessions; never enter unmarked or restricted thermal features in national parks; and treat wild water as a privilege—pack out everything you bring in.
Clothing norms differ wildly: swimsuits at most Western spas and wild pools; nude, gender-separated baths in many Japanese and Taiwanese public onsen; clothing-optional pockets at some California springs. When you are unsure, watch what locals do for thirty seconds, or ask the front desk—awkwardness beats accidental disrespect.
Temperature is not a personality test. If a pool feels too hot, step out, cool down, and try a milder basin. Wild rivers can have scalding pockets near vents; commercial spas usually post approximate ranges. Listen to your body more than to anyone’s “you must stay in for twenty minutes” folklore.
I have soaked at Banff Upper Hot Springs, and it still feels like the classic Rockies reset: mineral water, mountain air, and the odd chipmunk eyeing your towel. The pools sit just above town on Sulphur Mountain’s flank—close enough that you can pair a soak with the gondola parking area and a walk through Banff’s streets the same afternoon. On cold days the steam hangs in a soft curtain; on clear evenings the peaks turn pink while you float. It is not a secret wilderness tub—it is Banff’s communal living room—and that social energy is part of the charm.
Banff’s “must-sees” are crowded for a reason—and I still put the Upper Hot Springs on the list every time. Pack a simple bag, go when you can linger, and let the mountains do half the work.
This is a managed Parks Canada site, popular with locals and visitors alike, so expect company in peak seasons and after ski days. Entry is typically first-come rather than a complicated advance-ticket ritual; the smart move is to check the official Parks Canada Banff springs page for seasonal maintenance closures before you drive up. When the outdoor pool steams against snowy peaks, it is hard to argue with the setting.
Afterward, I like a simple evening in town—nothing fancy required. The soak is the point; the Rockies do the rest of the storytelling.
Tips:
Confirm current opening status on Parks Canada before you go—renovation and maintenance closures happen.
Bring a swimsuit and flip-flops; peak hours fill the deck quickly.
Combine with Sulphur Mountain views or a gentle town walk rather than rushing back to Calgary the same hour.
A thermal bath does not need to be grand. On my jeep route toward the Uyuni salt flats from the Atacama side, we stopped at Aguas Termales de Polques—a modest pool in the high desert that felt like a gift after dusty days of lagoon and volcano scenery. It is not a casual roadside spa you “drop into” on a city itinerary; it belongs to the expedition rhythm of the Altiplano, where the soak washes off the jeep and the horizon does the healing.
If you are building a Bolivia–Chile salt-flat circuit, ask your operator whether Polques (or a similar desert spring) sits on your day’s route, and go in with soft expectations: small pool, huge sky.
Arenal National Park wraps an active volcano in cloud forest, waterfalls, and—yes—thermal water. The river that feeds La Fortuna waterfall picks up heat as it crosses volcanically active ground, which is why this corner of Costa Rica is famous for both luxury spa resorts and free riverside pools.
If you want lockers, landscaped paths, and a proper changing room, Tabacón and similar resorts deliver a polished soak (day passes and overnight stays both exist—confirm details on the official resort site). If you prefer a frugal adventure, local tips point to informal river pools near the resort bend: trees for privacy, no facilities, and a reminder to watch your belongings. Rainy-day soaks here can feel oddly perfect—warm water, cool rain, green everywhere.
Bring a swimsuit, water shoes if the rocks are slippery, and the humility to leave the free pools cleaner than you found them. Arenal belongs on any Costa Rica nature list for a reason. A rainy-day soak with mist on the canopy is, frankly, better than a perfect sunny postcard.
Whether you choose Tabacón’s landscaped lagoons or the free river pockets, keep valuables minimal and follow local advice on where changing is discreet. Pair the thermal stop with La Fortuna waterfall or a park hike so the day feels like Arenal, not only a spa transfer.
Las Grutas de Tolantongo (toe-lawn-tong-go) is Mexico’s most famous thermal playground: a canyon complex fed by underground heat, with pools, a river, tunnels, and a cave where the water itself is warmed. It sits roughly a half-day from Mexico City in Hidalgo—popular as a day trip, even better with an overnight so you can explore without sprinting.
Weekdays are dramatically quieter than weekends. The site is large enough that “two full days” is not an exaggeration if you want pools, cave, tunnel, and river without rushing. On-site hotels and riverside camping options exist; check current admission and lodging on the official Tolantongo channels rather than outdated blog prices.
What surprises first-timers is the vertical drama: water tumbling from cave mouths, terraces stacked on canyon walls, and the option to wade into the source cave itself when conditions allow. Move between zones rather than camping in one pool all day—the river stretch feels different from the upper terraces. Keep cash/card options flexible and follow posted safety signs around wet rock.
Tips: visit midweek when you can; wear water shoes; and give yourself time—this is a destination, not a quick dip.
On an Alaska road trip, Chena Hot Springs Resort is the classic Fairbanks-area soak: an indoor pool plus a memorable outdoor rock lake where steam meets cold air and, with luck, wildlife at the edges. The mineral water is pungent and properly hot at the source; the outdoor lake is where most travelers linger for the mountain-and-forest backdrop.
Staying on-site makes it easy to combine soaking with the ice museum, short trails, and—in the right season—northern lights watching from a dark sky. Day visitors can usually purchase soak access without an overnight; confirm packages and road conditions on the resort’s official site before you drive out of Fairbanks. The outdoor lake is the memory most people keep—steam, cold air, and the odd moose rumor at the pond next door.
Build Chena as a destination night or two rather than a rushed turnaround from Fairbanks if aurora season is on your wishlist; the dark skies outside town are part of the package even when the lights stay shy.
The Long Valley Caldera around Mammoth Lakes hides a scatter of free, mostly primitive hot springs—cement tubs and rock pools maintained by volunteers, with no resort polish and all the Sierra quiet that implies. Several lie a short drive from town; a couple more reward a little further exploring. Sunset soaks, with the range going pink and stars arriving overhead, are the local legend for a reason.
Come prepared: no facilities, variable temperatures, and Leave No Trace. Some pools are cement-lined, others are grit-bottomed rock tubs—none of them pretend to be a spa desk with wristbands. Dispersed camping is popular in the wider caldera; if you want a proper bed, Mammoth Lakes town has plenty of lodging. For pool-by-pool detail, the Mammoth Lakes hot springs guide from Sophie and Adam is a solid deep dive.
Travertine Hot Springs sits above Bridgeport with an almost unfair view of the Sierra. A short trail leads to small natural pools under pale travertine—intimate enough that early mornings and midweek visits matter. The springs are often clothing-optional; go with that expectation, or choose another soak if it is not your scene.
Pair the soak with Mono Lake’s tufa towers the same day if you are road-tripping Mono County. Lodging is simplest in Bridgeport itself.
Umpqua Hot Springs is a string of small rock tubs carved into a cliff above the river—short trail, steep sections, roots and gravel underfoot. Hiking shoes help on the walk in; water shoes help in the pools. Parking is limited and the site is popular, so early arrival is the difference between a quiet soak and a queue.
These springs have closed before when trash and waste piled up. Pack out everything, stay on durable surfaces, and treat the place as day-use wilderness rather than a party stop. Tiny parking and tiny tubs mean courtesy matters: share time, keep voices low, and leave no soap in the water. Check the Umpqua National Forest pages for road and trail status, especially in winter.
Yellowstone is the geothermal capital of the American imagination: Grand Prismatic’s rainbow rings, hissing fumaroles, boardwalks over crust you must never step off. It belongs on a world hot-springs list as a thermal wonderland—even though most features are far too hot (and strictly off-limits) for soaking.
Important: swimming or soaking in park hot springs is prohibited. The once-popular Boiling River soak is not available; the National Park Service states swimming there is not possible after flood damage. Always read the current NPS Yellowstone swimming page before you plan any water time.
What you can do: walk the boardwalks, photograph the basins, and—if you want a legal commercial soak after park days—look at nearby private facilities outside the park (for example, developed springs north of the boundary in Montana). Treat those as separate businesses with their own tickets and rules, not as “Yellowstone pools.”
For routing the park itself, Nina’s Yellowstone itinerary is a helpful planning companion alongside official NPS maps.
Széchenyi is the bath I steer first-timers toward in Budapest: a vast Neo-Baroque complex in City Park, outdoor pools steaming in winter, indoor thermal rooms, saunas, and that unmistakable yellow courtyard.
I have soaked here on city trips, and it never feels like a throwaway tourist checkbox—especially when chess players claim a corner of the outdoor pool and locals treat the place as their neighborhood gym.
What I love is the range in one ticket: step from a cooler outdoor basin into hotter indoor thermal rooms, pause in a sauna, then wander back into the courtyard light. The architecture alone is worth the visit—palatial without being precious.
Budapest has other beautiful baths (Rudas, Gellért, and more), but Széchenyi is the one I replay when someone asks where to start.
Pools run cooler to warmer (roughly spa-to-hot, depending on the basin). Bring flip-flops, a swimsuit, and a towel—or rent on site if you forget. The complex can be busy; booking a ticket ahead on busy weekends is wise. For entrance options and add-ons, compare Széchenyi tickets on GetYourGuide or the official bath site.
It is almost impossible to write a world hot-springs list without the Blue Lagoon—and having floated there myself, I understand the hype. The milky blue water sits in a lava field near Keflavík, tinted by silica; the soft white mud at the bottom is part of the ritual smear-on-your-face moment everyone photographs. It is a polished spa experience, not a secret wild pool, and that is fine: lockers, pathways, swim-up bars, and package tiers exist for a reason.
My tip from experience: treat it as a spa appointment, not a hike you wing on arrival. Silica water leaves a soft film on skin and hair—many people rinse well afterward and pack a leave-in conditioner for the rest of an Iceland road trip. If you only have a layover window, the lagoon’s location between the international airport and Reykjavík is genuinely convenient; if you have more time, save a quieter wild soak (Reykjadalur) or a design-forward city lagoon for contrast.
Book ahead—popular slots sell out. Reykjanes volcanic activity can force temporary closures, so always confirm on the official Blue Lagoon site and Iceland’s SafeTravel advisories before you transfer from the airport or Reykjavík. Hotel guests at the Retreat / Silica side sometimes enjoy extended lagoon access; day visitors choose Comfort or Premium-style packages depending on towel, drink, and robe inclusions.
Gunnuhver is a sightseeing stop, not a soak: mud pots and steam vents on the Reykjanes Peninsula that show the same tectonic drama feeding Iceland’s spas. Stay on marked paths—the ground can be unstable—and treat it as a photo and geology pause between Blue Lagoon and the airport road.
Reykjadalur is the rare hot river: after a drive from Reykjavík and a hike of a few kilometers each way through a steaming green valley, you reach boardwalk-edged pools where the water runs jacuzzi-warm. Move upstream for hotter water, downstream for cooler. Changing space is basic; privacy is “hope few people are around.”
The hike itself is half the pleasure: steam vents along the valley, gentle hills, and that moment when the river temperature finally matches “bath” instead of “too much.” It is a summer favorite for a reason, though shoulder seasons can mean fewer people at the pools.
Wear sturdy shoes for the gravel trail, bring water shoes for the riverbed, carry water, and pack bug spray in summer. Rachel’s Reykjadalur guide covers the hike rhythm well. Stay on the boardwalk to protect fragile banks.
Saturnia’s free cascades—Cascate del Mulino—are the postcard of wild Italian thermal water: turquoise pools stepped down white sinter, steam in winter, Instagrammers at dawn. Locals and travelers share the river year-round. A few minutes’ walk away, Terme di Saturnia Natural Spa & Golf Resort offers a paid, full-service alternative if you want towels, treatments, and quieter basins.
The mineral water is strong; many guides suggest keeping soaks relatively short and listening to how your body feels. Soften any “healing” claims to wellness language—enjoy the warmth, rinse afterward, and skip the water if you have open wounds or medical restrictions. Families, couples, and photo hunters all share the cascades—patience and a morning alarm help. Arrive early for parking and a calmer pool. Martina’s Saturnia guide is a good companion for the free vs resort choice.
Kheerganga Hot Water Spring
Parvati Valley, Himachal Pradesh, India
Source: Abhishek, Misfit Wanderers
Kheerganga remains a classic Parvati Valley trek: green trails, waterfalls, orchards, and a mineral spring at the top that rewards the climb. What has changed is the overnight culture. Authorities have banned camping on the summit meadow; treat Kheerganga as a day trek with an early start from Barshaini / Nakthan / Kalga / Tosh, and confirm current entry windows and permits with local forest checkpoints before you go.
Bathing access is managed rather than the old free-for-all open pool many older blogs show—expect segregated, more structured facilities and pack a towel plus a dry layer. Carry water and snacks; do not assume cafés still operate on the meadow. Heavy snow can close the route in deep winter; shoulder and fair-weather seasons suit most first-timers.
Nearby Kasol, Tosh, and Manikaran remain easy add-ons. Always verify the latest Himachal forest guidance—rules here have tightened for good environmental reasons.
I have spent lazy hours at the Batur Natural Hot Springs above Lake Batur—stone pools at different temperatures, Balinese statues, and that wide crater-lake view that makes Kintamani feel worlds away from beach clubs. Any private driver from Ubud knows the road; weekdays are calmer than local weekend crowds.
What I remember most is the temperature ladder: hotter pools nearer the source, gentler ones farther along, so you can migrate as your body adjusts. After temple mornings and volcano viewpoints, sliding into warm water with the lake below feels like the pause Bali itineraries often forget to schedule. Bring a dry layer for the cooler Kintamani air when you step out.
Pools are filtered; towels and lockers are usually part of entry. Food is available on site (nasi goreng never fails me). Outside food is typically not allowed—check the desk when you arrive. Pair the soak with a volcano viewpoint morning or a temple circuit rather than treating Batur as a standalone half-day from the south.
Further north, Banjar Hot Springs is the lush garden complex many locals call one of Bali’s prettiest soaks—pools, spouts, and tropical planting. I also love Bali’s sacred water temples (Tirta Empul for purification rituals, Tirta Gangga’s royal water garden) as a cultural counterpoint to resort pools: dress respectfully, follow temple etiquette, and remember these are living religious sites first.

Dogo Onsen
Matsuyama, Ehime, Japan
Arima Onsen near Kobe is one of Japan’s historic “three famous springs.” Cable cars climb Mount Rokko for night views that rival Hakodate and Mount Inasa in Nagasaki.
In Japanese, a hot spring is an onsen—and with thousands of them across the archipelago, choosing favorites is a lifelong project. I have soaked my way through many towns and islands: quiet ryokan baths at dusk, city sentō after long train days, and famous resort streets lined with yukata and soft-serve. The ritual becomes familiar—shoes off, wash station, silent water—but each mineral profile and town mood feels different. One that stays with me is Dogo Onsen in Matsuyama, especially in cherry-blossom season when the castle town softens into pink.
Dogo claims one of Japan’s oldest hot-spring histories and a deep literary footprint; the public bathhouse’s silhouette is often linked to the bathhouse in Miyazaki’s Spirited Away. The Meiji-era tram station, Botchan clock, shopping arcade, and steam-train nostalgia make the neighborhood itself a reason to linger—not only the soak. I like wandering the arcade in yukata light after bathing, then finding a simple set meal—onsen towns reward unhurried evenings.
If Matsuyama is your Shikoku gateway, Dogo is the easiest historic bathhouse day: castle views, literature ties, and water that has drawn travelers for centuries. It is also a gentle introduction to onsen manners before you tackle quieter countryside ryokan.
Onsen etiquette, briefly: wash thoroughly before entering the bath, keep towels out of the water, speak softly, and check tattoo policies. For manners overviews, JNTO’s onsen guides are clearer than any blog tip list.
I have stood in the snow at Jigokudani (“Hell’s Valley”) in Nagano watching Japanese macaques claim the onsen for themselves. Humans do not join the monkeys in the water—we watch from paths while they soak, groom, and ignore our cameras. It is one of Japan’s most surreal wildlife moments, best in the cold months when the troop uses the park pool. Dress for snow and ice on the walk in, keep voices low, and remember the spa is theirs—our job is simply to witness. Pair it with a proper human onsen elsewhere in Nagano; see also my Nagano winter travel notes.
Beitou is Taipei’s urban hot-spring suburb—about a half-hour MRT ride from the city core—and I love it as a low-effort soak day after night markets and museum miles. Beitou Thermal Valley (Hell Valley) is the steaming green sulfur source you photograph rather than enter; for actual soaking, choose public gender-separated baths, co-ed outdoor pools in swimsuits, or private hotel rooms by the hour.
If sulfur scent bothers you, ask for white-sulfur water rooms with little odor. I like packages that pair a private soak with a simple meal afterward—bathing makes you hungry. Between dips, the Hot Spring Museum, library, and Plum Garden add a Japanese-colonial history layer. For a wider north Taipei loop, see my North Taipei scenic tour.
I have walked barefoot down Pamukkale’s white travertines—the “Cotton Castle”—and it still feels otherworldly: calcium terraces, pale blue catchments, and the ruins of Hierapolis stacked above. Arrive early for softer light and fewer elbows; shoes come off on the protected terrace path, so bring socks you do not mind getting chalky.
The first time the terraces appear from the approach road, they look almost unreal—like snow that never melts. Up close, the mineral texture is cool underfoot and the water sits in shallow basins rather than deep swimming pools. Hierapolis rewards a slower second half of the day: theatre seats, necropolis paths, and that sense that Romans chased the same warm water you came for. Stay overnight if you can; sunrise and late light are kinder than midday tour-bus hours.
Between the terraces and the ancient city sits the Antique / Cleopatra Pool, where you can swim among submerged columns when it is open. Access rules and tickets change—confirm everything on official Pamukkale / museum channels rather than old price lists. Overnight in the village keeps sunrise and sunset realistic.
Mataranka is a tiny Stuart Highway stop south of Darwin where RV travelers pull over for palm-shaded thermal pools and a float downstream on a noodle. The water is clear, fish keep you company, and—this being the Territory—freshwater crocodiles sometimes appear; management closes pools until animals are moved on. Harmless species or not, respect closures.
Think of Mataranka as an outback pause rather than a destination spa: shade from tall palms, warm clear water, and the social hum of road-trippers comparing Darwin–Alice stories. If you want solitude, aim for first light. If you want culture with your soak, linger for homestead evening entertainment when it is on.
Nearby Mataranka Homestead camping puts you within walking distance of the pools and classic outback evening entertainment. The dry season is the comfortable window for most travelers; go early in the day if you want quieter water. Check local park / tourism notices for crocodile-related closures before you unpack the swimsuit.
Rotorua sits on the Taupō Volcanic Zone with a soundtrack of sulfur and a skyline of steam. I have soaked here and wandered the geothermal parks—it is one of those places where the earth feels visibly restless. For a classic lakeside spa, Polynesian Spa’s outdoor rock pools (alkaline and acidic mineral options) are the easy recommendation; Hell’s Gate adds mud baths rooted in Māori healing traditions.
What makes Rotorua special for me is the cultural layer beside the spa steam. A soak after a village visit or geyser walk feels earned, not staged.
Lake views from the rock pools are the postcard; the sulfur scent on your clothes is the souvenir you pretend to mind. Build at least one full geothermal day—do not squeeze Polynesian Spa into a rushed airport transfer.
Auckland day tours often bundle geothermal parks with spa time if you are short on nights.
Doho is the wild card on this list: terraced baths on a ridge above a Rift Valley lake just beyond Awash National Park, reached most realistically through lodge arrangements rather than a pin on Google Maps. Think bushwalks, birdwatching, Afar-style lodgings, and sunsets that feel cinematic—plus the honesty that remote Ethiopia requires current travel-advice checks from official government sources before you plan.
Doho rewards travelers who like edges: Rift Valley geology underfoot, wildlife on the periphery, and baths arranged along a ridge rather than inside a marble hall. It will not suit every itinerary—and that exclusivity is why it earns a place among twenty.
Wildlife shares the neighborhood; the lake has crocodiles, so follow lodge guidance about where bathing is considered appropriate. Ivan’s notes on Ethiopian wildlife lodges capture the atmosphere: this is a wilderness spa, not a city bathhouse.
Which Soak Will You Book First?
Twenty springs will never cover the planet—Japan alone could fill a lifetime—but this list spans the spectrum from free cliff tubs to historic bathhouses and silica lagoons. Use the comparison table to match vibe to trip style, then open the destination guides linked above for the logistics that change on the ground.
If you have a favorite wild pool, onsen town, or thermal bath missing here, leave a comment. I read them—and I am always looking for the next soak.
What is the difference between a hot spring, a thermal bath, and an onsen?
A hot spring is geothermal water rising naturally. A thermal bath usually means a built facility using that water (or heated mineral water). Onsen is the Japanese term and culture around hot springs—often with strict bathing etiquette.
Are hot springs safe?
Managed spas and baths post rules for a reason. Wild pools vary in temperature and depth; national parks often prohibit soaking in thermal features. Never enter closed or unmarked geothermal water, supervise children closely, and leave if you feel dizzy or overheated.
Do I need to book famous spas in advance?
Iconic commercial sites (Blue Lagoon, busy city baths, popular resort spas) often sell out in peak season. Wild pools rarely take bookings—arrive early instead. Always check the official site for your date.
Can I visit Japanese onsen with tattoos?
Policies vary. Some traditional baths still restrict visible tattoos; others offer private baths (kashikiri) or more flexible rules. When in doubt, email the ryokan or choose a private bath.
What should I bring to a hot spring?
Swimsuit where required, flip-flops, a quick-dry towel, water, and for wild sites: sturdy shoes and a dry change of clothes. In Japan, you may only need a small wash towel for public baths—follow local norms.
Is soaking good for health?
Many people find warm water relaxing and soothing for tired muscles. That is not the same as medical treatment. Soften expectations, stay hydrated, limit very hot sessions, and ask a doctor if you are pregnant or have cardiovascular concerns.
Why can’t I swim in Yellowstone’s hot springs?
Park thermal water is extremely hot and ecologically fragile. Soaking in hot springs is prohibited. Limited lake/river swimming areas exist under NPS rules; the former Boiling River soak is not available—see the official NPS swimming page.
Is Kheerganga still an overnight trek?
Plan it as a day trek. Overnight camping on the summit meadow has been banned; stay in valley villages and confirm current entry times and bathing arrangements locally before you go.
This is amazing. Thermal bath? Nature is just beautiful. You’ve done great compilation here. I never knew of some of the mentioned places. I’ve got new additions for my 2022 bucket list
Hhhhmmmm…it is my first time seeing a thermal bath. I wonder if the effect is or can be the same as for the person in the hot springs! Also, it’s nice to learn of other hot springs around the world. Thanks for sharing about them.

Amazing places to bath..
And so many 😂
I left going to the Hot Springs in Costa Rica. They were so beautiful and when they had a waterfall attached they were extra special.
Nice to know!
This is amazing. Thermal bath? Nature is just beautiful. You’ve done great compilation here. I never knew of some of the mentioned places. I’ve got new additions for my 2022 bucket list
They are amazing and hope you will go to some soon!
