9 of the World’s Most Beautiful Hot Springs

A short drive north of Fairbanks, the Chena Hot Springs offers you the opportunity to take in views of the vibrant northern lights while soaking under the night sky—if you time your visit for the right time of year; roughly August through April.

But even if you can’t stop by during the aurora borealis season, it’s still worth visiting to take a restorative soak surrounded by trees. And, regardless of the time of year, don’t leave before checking out the on-site Aurora Ice Museum, where you can sip an appletini from a glass made of ice or simply peruse the fantastic collection of intricately carved ice sculptures.

Situated in Hidalgo State, the Grutas de Tolantongo (or the Tolantongo Caves) offer a mix of human-made and natural features, including caves, a waterfall, a suspension bridge, and—of course—hot springs. Here, go for a swim in the shallow thermal river or take in the views from one of the many terraced hillside pools. And best of all, the springs can easily be reached on a day trip from Mexico City, roughly a 4-hour car ride away.

Insider tip: The Grutas de Tolantongo get especially busy during school holidays and on weekends. Go midweek, during the November to May dry season, for the quietest experience and clearest waters.

The newest of Reykjavik’s thermal spa complexes, Sky Lagoon features a massive, hot springs–fed lagoon with an infinity edge and views out over the sea. There’s even a swim-up bar, tucked away in a cave.

If you're sold on this particular hot springs experience in Iceland, know that the best way to experience the lagoon is by participating in a 7-step spa ritual circuit, which includes a cold plunge and a sauna with floor-to-ceiling windows and the same fantastic sea views found in the main bath.

Situated in the aptly named city of Bath in the west of England, the Roman Baths are among the UK’s most celebrated historic attractions. Although the waters here have been used since pre-Roman times, the current bath complex dates to the 1st century AD, with additional street-level structures dating to the 18th and 19th centuries.

While you can’t soak in the waters at this particular historic site—though many walking tours of Bath will stop by the baths themselves—you can reap their benefits by heading over to the more modern Thermae Bath Spa complex, a couple of streets away.

Soaking in curative hot springs is an integral part of life in Budapest—you can even get a doctor’s prescription to soak away your aches and pains. As such, the Hungarian capital is chock-full of places to soak, from the art nouveau Gellért Thermal Bath and Spa to the 16th-century Rudas Thermal Baths. If you have to choose just one though, go for Széchenyi Thermal Baths, which features a complex of indoor and outdoor pools housed in a palatial neo-baroque spa complex. And once you've finished with your rest and relaxation, take a walking tour of Budapest to see what else the city has to offer.

Turkey’s UNESCO World Heritage–listed Pamukkale Thermal Pools have been attracting hot springs fans since the Roman era with their white travertine terraced pools that bear a resemblance to flattened clouds. (Pamukkale actually means "cotton castle.")

Though you can visit independently, most people combine a trip to the pools with a visit to the nearby ruins at Hierapolis, and you can easily see both sites on a day tour from Kusadesi.

A short drive from the Dead Sea resorts in Jordan—where you definitely should enjoy some floating action—this thermal spring is fed by hot waterfalls that cascade into a deep soaking pool below. While some visitors opt to stay the night at the on-site hotel, if you’re short on time you can easily visit the springs on a day tour from Amman, or simply stop off for a soak on the way to Petra.

The Banjar Hot Springs complex in northern Bali is worth visiting for both its sulfur-rich waters and its beautiful architectural features. Popular with Balinese locals and international visitors alike, the terraced bathing pools here are fed by rows of intricately carved dragon heads that shoot water through their mouths.

Many northern Bali day trips include stops at the springs; for a more flexible option, simply charter a car with a driver for the day.

If you love hot springs, you can’t go wrong with a trip to Japan. Geothermal baths, known as onsen, can be found throughout the country, and many communities—such as Beppu and Kusatsu—have entire tourism industries based on soaking.

Perhaps the most famous (or at least the most photographed) onsen in Japan is in Jigokudani Monkey Park. Here you can observe resident macaques as they warm up in the thermal waters. And while you probably won’t want to (or rather can't) join in on the fun, you’ll find plenty of human-friendly hot springs in the nearby resort town of Yudanaka Onsen.
