Tucked away in the heart of Monaco, overlooking the shimmering Mediterranean, Thermes Marins Monte-Carlo stands as a premier destination for those seeking deep relaxation and rejuvenation. Spanning over 6,600 square meters, this wellness retreat blends cutting-edge treatments with timeless elegance, offering a full suite of services—from fitness and beauty to medical wellness and holistic health.
Modern life brings its own challenges—screen fatigue, pollution, burnout, and sedentary routines—and the team at Thermes Marins responds with tailor-made solutions. Visitors are guided by a multidisciplinary team of physicians, nutritionists, therapists, and coaches, all committed to restoring balance and energy.
Royal vision behind the legacy
The origins of this luxurious spa trace back to Princess Marie Caroline of Monaco, a visionary figure who saw the potential of her homeland’s natural beauty and climate. Her efforts, alongside Prince Charles III, laid the groundwork for Monaco’s transformation into a wellness and leisure hub. The Princess personally helped convince François Blanc, a renowned French entrepreneur, to invest in what would become one of the most iconic spa destinations in Europe.
Since its early days in the 19th century, Thermes Marins has continually evolved, adding a gym in 1908, an indoor pool in 1949, and a panoramic fitness studio in 2014. Following major renovations in the 1990s, the facility was reborn, merging tradition with innovation. Today, guests enjoy a seawater pool with underwater jets, elegant glass walls that reveal sweeping sea views, and modern amenities like beauty lounges staffed by expert hairdressers.
New arrivals: Decorté treatments and family-friendly experiences
In January 2025, the spa introduced a new partnership with Japanese skincare brand Decorté, replacing its previous line of facial treatments. Guests can now experience three signature facials, including one specifically designed for men, all incorporating Decorté’s signature fusion of neuroscience and traditional Japanese beauty rituals.
Families are also welcome—with the launch of a new family package that includes children’s sports activities, mini-massages, and even hairdressing sessions for the little ones, turning a day at the spa into a shared moment of serenity.
Caviar, gold, and cryotherapy: beauty that dazzles
The facial treatment menu is as extravagant as it is effective. One standout is the Prairie Caviar facial, which uses caviar beads to smooth and tone the skin, while the Pure Gold Radiance Treatment adds a luminous glow using real gold particles. Cryotherapy, collagen boosters, LED light therapy, and eyelash enhancements via the popular Yumi lash lift round out the offering.
Body treatments are equally impressive, ranging from sea mud wraps and salt exfoliations to advanced sculpting via radio frequency and electric current. The massage menu includes techniques like Thai, Shiatsu, lymphatic drainage, and the herbal Pinda Sweda ritual.
Tech-powered sculpting: Endotherm Reneve
For those seeking contouring and firming, the Endotherm Reneve treatment blends light exfoliation, targeted technology, and a finishing massage. Each session is customized to suit individual goals, providing noticeable results in skin tone and firmness. The experience is priced at €205.
L’Hirondelle: where wellness meets gastronomy
Under the guidance of Chef Jean-Laurent Basile, the L’Hirondelle restaurant offers dishes that are as nutritious as they are delicious. The daily menu includes vegan, vegetarian, gluten-free, and detox options, with a focus on local and sustainable ingredients—especially seafood. With its stunning terrace view of Monaco’s harbor and the Rock, every meal becomes a sensory escape.
Guests can opt for a two-course meal (€60–70) or indulge in a full three-course experience for €85.
Sustainability at its core
Beyond luxury and relaxation, Thermes Marins Monte-Carlo is committed to environmental responsibility. As a partner of the Mr. Goodfish program and a supporter of the Prince Albert II of Monaco Foundation, the spa prioritizes responsible sourcing and eco-conscious operations. Its in-house Green Spa Team, active since 2014, meets regularly to develop environmental and social initiatives.
With its seamless blend of tradition, innovation, and sustainability, Thermes Marins Monte-Carlo continues to set the gold standard in holistic luxury. Whether seeking healing, rest, or transformation, this serene destination offers a refined escape shaped by the sea and the spirit of Monaco.
