These shallow thermal pools offer incredible sunsets views over California’s Eastern Sierra.

You’ll find Travertine Hot Springs a five-minute drive from Bridgeport and, be warned, clothing is optional. 

This remote, rustic geothermal hotspot in Nevada offers incredible views. You’ll find a cluster of bathing areas, with most of the baths made from cattle troughs – the metal keeps the spring waters at a deliciously warm 54°C (129°F), year-round. If you’re lucky, you’ll spot the local herd of wild burros as you soak up the expansive vistas. Spencer hot springs is 12 miles (19km) east of Austin, on Highway 50.

Fancy a thermal-themed road trip? You can explore 19 of Colorado’s hot springs (there are over 30) from the Historic Hot Springs loop, a 720-mile (1,159km) route taking in some of the best in the state. Make sure you visit Glenwood Hot Springs, which is one of the world’s largest mineral baths and open year-round. The gigantic main pool contains a staggering one million gallons of water (at 32°C [90°F]), while the warmer therapy pool is 100 feet (30m) long.

Dubbed the world’s only drive through volcano, Soufriere in St Lucia offers the chance to take a bath in thick, oozing, mineral-rich mud. Once you’ve wallowed, wash it off with a cleansing dip in the thermal spring waters. Be prepared for the sulphurous smell! To get the best of the Caribbean weather, visit between December and April.

Granted, the Blue Lagoon gets crowded, but the sight of the milky blue waters set amidst the black volcanic landscape is still striking. Technically not entirely natural – the pool was the accidental result of drilling by the next-door geothermal power plant – you can wallow in the 37-40°C (99- 104°F) waters, have a massage, plaster on a free, silica-rich facemask, or sweat it out in a steam room and sauna. To minimise queuing, buy a ticket that includes your towel and robe in advance and get there early. 

Tucked away in the wilderness of Whiteswan Lake Provincial Park, you’ll find three stunning natural pools, surrounded by boulders. Dip into the toasty 44°C (111°F) waters and clear your head while you look out over the Lussier river and forested valleys. To access the hot springs, you need to take a short walk from the Whiteswan Forestry Road to the Lussier River. Keep watch for golden eagles, kingfishers, deer and of course bears. Visit in summer, when the roads are clear of snow. 

Dubbed Japan’s hot spring capital, Beppu is trumped only by Yellowstone Park when it comes to sheer volume of thermal waters.

You can even take a sand bath, where your body is buried under hot, black, volcanic sand. Travellers can also visit (but not swim at) The Hells, seven hot springs that range from a boiling turquoise pool to a steaming, blood-orange pond. Visit May-October. 

In China’s Huanglong Valley, hot spring water cascades down a series of intensely aquamarine terraced pools, creating a breathtaking spectacle. Formed from calcium carbonate, the ponds and lakes stretch for over two miles (3km) through the valley, which is home to giant pandas and the Sichuan golden snub-nosed monkey. You can't bathe here, but you'll see why Huanglong is known as 'Fairyland on Earth'. Visit in October to see it at its most beautiful.

This North Island city is built on an active volcano and has several hotels offering spa pools, but Kuirau Park is not to be missed. Right in the heart of the city, it has hot springs, mud pools and a bubbling crater lake.

From Romans to Royals, the rich, healing waters in Austria’s Gastein Valley and glorious Alpine views have been drawing visitors through the centuries.

From healing mineral waters to dramatic geysers, Chile’s Atacama Desert is a hotspot for geothermal activity. At Puritama, you’ll find eight crystalline pools, set within a startling green oasis.

You’ll find Wai-O-Tapu 20 minutes south of Rotorua.

At El Tatio, in Chile’s Altiplano region, powerful shots of steam jet out from geysers (for obvious reasons, no bathing allowed).

You’ll get to lower yourself into a deliciously warm thermal pool and rest while you soak up breathtaking views. You can camp nearby, but the use of bear canisters is enforced. Find the Conundrum Creek Trailhead off Castle Creek Road, south of Aspen. Go between spring and mid-autumn, when the snow has melted.

Liard River Hot Spring, near the British Columbia-Yukon border, is Canada’s second-largest hot spring. With water temperatures reaching 52°C (126°F), locals flock here to stave off the winter chill. The warmth here has created a tropical micro climate, where 14 species of orchid bloom. Look out for moose, which feed in the warm water swamps.

With its vivid blue centre, surrounded by bands of yellow, rusty orange and green, Grand Prismatic Spring in Yellowstone National Park looks almost otherworldly. The depths of this lake, filled with bubbling thermal waters, plunge as deep as 160 feet (49m). The psychedelic colours are caused by bacteria in the water. You can't bathe here, but head north to Mammoth to enjoy a soak in Boiling River. 

In the late 20th century, two brothers drilled a borehole some 2,000 feet (610m) into Australia's Mornington Peninsula in a bid to access the geothermal waters deep below the surface.

There’s also a traditional sauna and Moroccan hammam. You’ll find Peninsula Hot Springs 90 minutes from Melbourne.

Niseko, on Hokkaido island, is as famous for its volcanic springs as it is for its pristine powder snow. After a day on the slopes, strip off and warm up in one of the many onsen. There’s a strict code of behaviour at play – tattoos are forbidden, bathers are generally expected to be naked and the majority of hot springs segregate men and women. If you want to mingle with the opposite sex, try the onsen at the Niseko Grand Hotel. For plentiful snow, visit between December and April. 

One of the world’s biggest salt pans, the Salar de Uyuni is surrounded by snow-dusted volcanoes and thermal springs.

As thermal springs go, Hot Water Beach on North Island’s Coromandel Peninsula offers a unique experience.

These tiered pools in Turkey are filled with milky white, hot spring water and have formed from limestone deposits over millions of years. The 17 terraces are strictly for looking at, not swimming in, but you can bathe in thermal waters at Cleopatra’s pool, above. To beat the crowds, stay in nearby Pamukkale village and visit in the early morning. The best time to go is spring, when the weather is clear but not too hot.

You can't bathe in these, but Dallol Sulphur Springs in Ethiopia’s Danakil Depression offers a mesmerising landscape that wouldn’t look out of place in a sci-fi movie. Here, steam is spewed out from fissures in the Earth’s crust and the boiling magma below the surface heats the watery pools. The rocky salt deposits get their striking, neon colours from minerals dissolved within the waters. Visit in November or December, when the searing heat lessens. 

These magnificent hot springs are about a four-hour hike from India’s Barsheni village in the Parvati Valley, but we promise it’s worth it.

There’s also a Hindu temple nearby, allowing visitors to get in touch with their spiritual side after a dip.

The Chena Hot Springs were discovered in 1905, when a pair of gold mining brothers struck a little more than they bargained for.

Situated roughly 60 miles (97km) from Fairbanks, Alaska, the springs are now part of a luxurious resort, the area’s main attraction.

With temperatures up to 38°C (100°F) and a 26% sulphur content to help soothe irritated skin, the Banjar Hot Springs of Bali, Indonesia are famed for their healing waters.

Known as Kerosene Creek, these beautiful hot springs were a well-kept secret for quite some time thanks to their remote location in the Rotorua region of the central North Island of New Zealand. The natural hot spring flows downhill through the bush and into a collection of pools, creating a jacuzzi-like experience for bathers. The best part? The spring has yet to be commercialised and it's completely free to visit.
