Wellbeing has never been more “in”. Whether you spread yourself in spirulina every night, drink endless amounts of nettle tea or are a dedicated meditator, we all seem to be jumping on the beautifying mind-and-body bandwagon. Once a darkened, sweaty room offering offering a mani, massage and a hot tub (if you were lucky) spas are now specialist, divided into categories which can be anything from Ayurvedic to healing, thermal, hammam and thalassotherapy. From the naturally occurring to the whispered secrets of the 1% – these are some of the best spas in the world.

Grotta Giusti, Tuscany

Hidden beneath the 19th-century Tuscan villa which was once home to the late poet Giuseppe Giusti, you’ll find one of the spa world’s best-kept secrets. Described by Giusti himself as “the eight wonder of the world”, this humid grotto houses a subterranean hot-spring lake and acts as a natural steam room. Try floating therapy, an underwater hydro-massage in the open-air pool, or go one step further with a fantastical spa-scuba-diving lesson. Today, the villa is a grand 64-room hotel while the grotto offers an extensive list of weird and wonderful treatments.

Kusatsu Onsen, Kusatsu, Japan

Resting in the mountains north of Tokyo is the small town of Kusatsu, home to one of Japan’s most beautiful hot springs or “onsen.” Here, the thermal water flows naturally from the active volcano, Mount Shirane, and is passed through Japanese cypress-wood channels to bring the temperature down to a (still toasty) 48 degrees – tolerable thanks to the high-mineral content. The key to the water’s healing powers lies in its high acidity – an aluminium yen coin would dissolve in the pools in less than a week. Although this might not have you rushing to dip your toes in, the waters are renowned for their antibacterial healing properties – rumour has it the only ailment they can’t cure is heartache.

Huvafen Fushi, Maldives

The Maldives are pretty flawless – pale sands, azure-blue waters, towering palm trees etc, etc, etc. Now forget all that. At Huvafen Fushi they’ve bypassed the beach and set their sights on the seabed. One of the world’s only underwater spas, Lime is an all-glass space that tends toward with avant-garde (and has a treatment menu to match). Banish jet lag with a bubbling marine-mud body wrap, detox with a spirulina scrub after a cocktail-fuelled evening or prep your skin for a day on the beach with a homemade lime and sea-salt exfoliation. Ariel ain’t got nothing on you, honey.

Aire Ancient Baths, New York, US

Clinical spa experience this is not. One of New York City’s most under-the-radar spas, this Tribeca-based subterranean retreat is as atmospheric as you’ll find this side of the Hudson (although they have also sprouted other locations in Seville, Barcelona and Almeria). Located in a former textile factory built in 1883, the Aire Ancient Baths is most suited to those who like a good soak. Fusing traditions from the Greek, Roman, Ottoman and Arab empires, the prevailing idea here is the Romans’ custom of hopping from frigidaria to caldaria (i.e. progressing from cold to hot pools). Slippers are provided, caverns are flooded with candles (the only source of light) and all you’ll need to pack is your swimsuit.

Yaan Wellness, Tulum, Mexico

Those in the market for a holiday focused on well-being and relaxation and should book a trip to Yaan Wellness pronto. Looking at health from a full-body perspective, the approach is holistic and the surrounds are transfixing. Guests can (and mostly do) opt in for cleanses and detoxes – who’s ready for a week of colon hydrotherapy, medical massages and a juice cleanse? For something a little less hardcore, take a yoga class or meditation at treetop yoga shala. After an hour of sun salutations, experience your first Moon Temazcal Ceremony (which takes place twice monthly on the new and full moons) and put your cynicisms to one side. In the spa, natural cenote waters and purified crystalline springs from the Yucatan’s natural sinkholes offer a boost of vitality, while the spa menu of indigenous treatments is sure to impress.

The Ranch, Malibu, US

A programme advertised as having “no options” is indicative of it’s hardcore approach to wellbeing. Mandy Moore, Lea Michele and Selma Blair have all sweated it out at this week-long luxury boot camp in the mountains of Malibu. Words of caution: if you are a crier, came last in the bleep test at school or are a bit of a Malibu Barbie, you might want to sit this one out. At The Ranch it is all about personal awareness and life transformation – physically, mentally and spiritually. You won’t eat a lot – not unless you consider six almonds a proper snack. Still, vegans and plant-based dieters will coo over The Ranch’s signature granola with almond milk (its scrumptious – or is that the starvation talking?). Food rationing aside, The Ranch is a results-driven destination. Trainers wake guests at 5.30am each day for their morning four-hour hike. And that’s just a warm up.

Lanserhof Lans, Tyrol, Austria

This sci-fii-esque forest compound in Austria marries salubrious practices with medical prowess. Naturopathy and modern medicine are words you’ll hear frequently, murmured down minimalist corridors. Here, practice centres around intense detoxification (from colon cleansing to lymphatic draining). Whether your ailments are desk-related or you suffer from digestive issues, the medical consultation on day one will get down to the nitty gritty and set about resetting your mind and body throughout a seven to 10 day stay. As intense as the programme reads (and it’s not to be entered lightly) it’s all balanced by ample spa time for salt scrubs and massages. Custom (albeit skimpy) meal plans border on gourmet and keep hungry tums content.

Amanemu, Shima, Japan

Three hours by train from Kyoto, you’ll reach Amanemu. Designed around a large hot spring, the spa incorporates mineral water and salts from pearl-rich Ago Bay into its treatments. Ryokan-inspired, the retreat comes complete with low-hanging tiled roofs and sliding screens, surrounded by UNESCO pilgrim trails and sacred forests. How zen can you get? Treatments include signature massages and facials, body scrubs, hot-stone therapies and reiki. While the outdoor infinity pool – which also makes an ideal spot for stargazing – is understandably alluring, the yoga studio and four treatment rooms hedged by forest will beckon any bathing beauty out of the water. Meals at spotlight the region’s izakaya-style seafood offerings and come lunch, bento boxes of sashimi and tempura are coveted commodities.

Agua Bathhouse and Spa, London

Set in Mondrian London at Sea Containers, Agua makes for a particularly glamorous spa experience (guests of the hotel are given complimentary access, as well as to the gym). Go with a gang and set the relaxation room as your group meeting point. Centring on a singular golden droplet, the surrounds sets the tone for the decadent afternoon in store. If your nails are in need of a little TLC post massage and steam, The Glamour Room is a must. Preen, prettify and pamper before heading to the Rumpus Rooms on the rooftop for an Aperol spritz – by which time you’ll be too relaxed to worry about your trite drinks order.

Tierra Santa Healing House, Miami

Don’t come here if your idea of zenning out involves all-white surroundings. Tierra Santa is awash with rainbow-hued rugs, a pom-pom chandelier, bright Juan Gatti artwork and floral-printed pouffes. Located on the third floor of Faena Hotel, the spa boasts one of the largest hammams on the East Coast. Indulge in a full wet-spa experience – think herbal steam room, sauna and ice parlour – and book in for the Hamam Rose Ritual; a unique treatment which involves lying on top of a warm marble slab while a therapist scrubs you down. Post rigorous exfoliation you’ll be covered in soft foam, then a soothing clay and conclude with a massage. Inspired by South American and South Asian healing traditions, Tierra Santa’s treatments are far reaching. Led by two partnering doctors, Tierra Santa also has a preventive medicine program, including testing, exams, detox and digestive health offerings. Weekly spa treatments are far more justifiable when they’re listed under “doctor’s orders”.
