[BARCELONA, Spain] March 2026 — SLS Barcelona is making waves with the opening of Halcyon Spa, a new wellness playground at Port Fòrum. Less about retreating from the spotlight and more about stepping back into it, Halcyon adds a refreshing dimension to the resort’s seaside stage, delivering indulgent rituals that leave guests radiant and ready to make an entrance.
In the age of product hyperactivity we currently exist in, Barcelona's slower-paced, vibrant lifestyle makes it an appealing destination for travel wellness, especially for those who struggle to unplug and detach from deadlines. The Halcyon Spa upholds this luxurious, relaxing feel, all while working to restore (or maintain!) a client's radiance so that they're ready to meet the city with their best face forward.
Designed by Rockwell Group, Halcyon draws inspiration from the way light dances across water, guiding guests from bright, luminous arrival moments into moodier, immersive interiors. Halcyon partners with Barcelona-born skin care brand SEPAI, specializing in dermo-hacking and smart-aging innovation, to bring its customizable, results-driven formulas into a luxury hospitality setting.
The extensive menu spans high-impact “Signatures,” glow-boosting “Flawless Facials,” deep-release “Let Loose” massages and targeted “Body Talk” treatments, all crafted to elevate beauty, boost confidence and reveal results that linger long after checkout.
Treatment highlights include:
The Lift: A facial and body treatment powered by advanced 3D light technology, designed to firm and sculpt for visibly lifted contours, refined tone and a smooth, luminous finish.
Ray of Light: A multisensory face-and-body experience combining reparative skin care with aromatherapy, music and fluid massage techniques to reset the senses and bring skin and mood back into focus.
The Fast & The Fabulous: A fast-acting, 30-minute facial with instant payoff, delivering camera-ready radiance and a plump, juicy glow, perfect before events or evenings out.
Hydra-Platinum: A true thirst trap, this all-encompassing facial delivers intensive moisture and refined texture across face, neck, décolleté, eyes and lips.
For those who prefer to unwind with company, Halcyon offers “Plus One” experiences such as the Shine then Dine, an exclusive two-person treatment that concludes with a private gourmet dinner served in the same space.
With the opening of Halcyon Spa, SLS Barcelona further defines itself as the city’s ultimate urban resort, where bold design, destination dining and feel-good wellness collide.
