Les Thermes Marins de Monte-Carlo is a landmark thalassotherapy centre located at the water's edge in Monaco, steps from the Hôtel de Paris and the Casino de Monte-Carlo. Operating since 1993, the centre occupies a five-storey building overlooking the Mediterranean, drawing on the therapeutic properties of seawater for its core treatments. The facility is anchored by a 750-square-metre seawater pool heated to 30°C, equipped with underwater jets, geysers, and neck showers that form the thalassotherapy circuit. Guests circulate through a sequence of hydrotherapy stations — buoyant seawater pools, pressurised jet alcoves, and a large relaxation basin — before passing through the hammam, sauna, and ice fountain. The circuit alone takes three to four hours for a thorough visit.
Beyond the main circuit, the centre offers a full programme of individual treatments carried out by trained balneotherapists. Marine body wraps use algae delivered in heated cocoons that encourage deep relaxation and detoxification. Relaxation massages range from Swedish to deep-tissue, with the option to combine a massage with the full thalasso circuit in a half-day package. Facial treatments using Guerlain products complete the menu. The centre's reputation for rigorous thalassotherapy — rather than purely cosmetic spa services — draws a devoted clientele from across the Côte d'Azur and international visitors using the adjacent Société des Bains de Mer hotels.
Facilities include a fitness room, a heated outdoor pool terrace with Mediterranean views, and a light-lunch counter serving mineral water, juices, and wellness cuisine. The entire space is decorated with Mediterranean blues and mosaic detailing that reinforces the nautical atmosphere. Robes, towels, and slippers are provided as part of entry. Day access packages for non-hotel guests are available, making this one of the most accessible luxury thalasso destinations on the Riviera. Booking is recommended for individual treatments; circuit entry can sometimes be arranged on the day.

Tips for visiting
- Book individual treatments at least one week in advance; circuit entry may be available on the day
- Arrive 20 minutes before the session — locker allocation, robe collection, and a short orientation take time
- The circuit is co-ed; gender-separate changing rooms adjoin the shared hydrotherapy hall
- Half-day packages combining the circuit with one treatment offer better value than booking separately
- Bring flip-flops — house sandals are basic and the pool deck can be slippery
