The World’s Most Beautiful Spas

Six Senses Zil Pasyon is where the Seychelles’ natural drama becomes the treatment room. Set along the edge of Félicité’s wild granite landscape, this is one of the world’s most beautiful spas—just ask Sarah Royall of Salty Luxe, who called it “one of the best” she has ever seen. The spa unfolds across five unique wellness villas, some carved between boulders, others perched above the ocean. Reached by winding stone paths and suspended rope bridges, each space feels like its own secret sanctuary. The experience leans into nature’s rhythms: holistic therapies using island botanicals, a saltwater infinity pool overlooking endless blue and open-air yoga pavilions that let the sea breeze finish the treatment for you.

This is what happens when a chalet decides to become a temple of relaxation. Lefay Resort & SPA Dolomiti’s spa stretches across four expansive floors, making it one of the largest and most immersive wellness destinations in the Alps—and one of the region’s most beautiful spas. Move through a world of elements: saunas of varying heat and humidity, aromatic steam rituals and energy-balancing circuits inspired by Eastern healing philosophies. The aquatic spaces are just as dreamy, featuring a tonalite-lined indoor pool, a magnesium-rich salt-water lake and a whirlpool reminiscent of ancient bathing traditions. And then there’s the indoor-outdoor pool, where warm water meets crisp mountain air and the Dolomites serve as the most magnificent backdrop of all.

Treatments draw on ancient Hellenic medicine and Chinese therapies, while personalized nutrition and fitness programs leave body, mind and spirit aligned.

Here, every detail works in harmony to leave you feeling simply euphoric.

Wrapped in steam, silence and soft blue light, The Retreat at Blue Lagoon feels like slipping into another dimension—easily one of the world’s most beautiful spas. The subterranean sanctuary is carved into volcanic rock and surrounded by its own private geothermal lagoon—warm, milky and rich with silica and algae straight from the earth. Wander slowly: from the lava-walled steam cave to the dry-heat sauna overlooking the water, to hidden coves where you can float without another soul in sight. The signature Blue Lagoon Ritual (a three-step mask experience performed in the water) leaves skin glowing and the mind at ease. And for peak bliss? Book an in-water massage and let the lagoon cradle every last worry away.

The Guerlain Spa at Raffles London at The OWO is London wellness turned wonderfully grand. Spread across 27,000 square feet and four dreamy floors, it pairs the building’s historic drama with an unmistakably modern calm. As London’s first Guerlain Spa, treatments are created just for this address—with expert touch, beautiful botanicals and high-tech innovation. Drift between the 20-meter pool under a soaring double-height ceiling, the vitality pool, sauna, steam rooms and softly lit lounges before slipping into a treatment suite (VIP rooms included). World-renowned reflexologist Andrea Hurst also practices exclusively here, bringing her intuitive, grounding touch, making it one of the city’s most beautiful spas. Finish your floaty bliss with a cold-pressed juice from Pillar Wellbeing’s nutritionist-designed menu.

At One&Only Reethi Rah, the spa begins with the sound of the ocean—your built-in soundtrack to slowing down. You arrive by wandering leafy paths, then slip into overwater pavilions where the breeze does half the work of relaxing you. Often called one of the world’s most beautiful spas, it’s a place where treatments feel almost like daydreams—from grounding aromatherapy to Watsu therapy that lets you float and stretch in warm, mineral-rich water. There are hammocks for napping, a vitality pool for soaking and yoga or meditation sessions that tune you directly into island time. For couples, a private overwater suite turns relaxation into a shared ritual. End with the crystal steam room and a refreshing sauna reset.

Like a Roman bathhouse hidden beneath the streets of Porto, the spa at The Rebello turns old-world ritual into modern-day indulgence. Set in a former cookware factory, the space holds onto its industrial soul while warming it with lantern light, clay-toned walls and a softly glowing cauldron-style pool at its center. Wander between the bubbling jacuzzi, cedar-scented sauna and Tranquility Water Lounge, where sun-and-moon lamps cast a gentle, mood-shifting glow. Treatment rooms draw inspiration from Chinese, Japanese and Indian wellness traditions, offering shiatsu, aromatherapy, reflexology and facials using organic Portuguese products. Whether you’re unwinding post-travel or sinking into the signature two-hour Rebello Ritual, the experience is a moment of calm in one of Europe’s most beautiful spas.

At Grand Resort Bad Ragaz, wellness doesn’t just happen—it flows. Literally. The spa is fed by the legendary thermal spring of the Tamina Gorge, meaning every dip comes with centuries of healing behind it. Considered one of Europe’s most beautiful spas, it invites slow wandering—whirlpools, steam rooms and the iconic Helenabad bath, where vaulted ceilings turn every soak into a moment. Indoors, outdoors, morning, night—there’s always a warm mineral pool calling your name. Even the bathtub in your room is tapped into the same thermal source. Treatments lean holistic, from lymphatic massages to herbal rituals and soothing thermal water therapies. And because relaxation shouldn’t feel rushed, the tranquil lounges, mountain views and impossibly plush robes encourage lingering.

Part sanctuary, part architectural daydream, Hyatt Regency Hua Hin and THE BARAI stand among the world’s most beautiful spas, turning wellness into an atmosphere you feel the moment you arrive.

Therapies blend centuries-old Thai healing with Western techniques, all personalized to balance your dominant element—earth, water, air or fire. Maybe that means a stretching Thai massage, a grounding herbal compress or a meditative bath ritual. Afterward, take it easy in the gardens or on the beach, where the Gulf of Thailand does the rest of the unwinding for you.
