Connected directly to the historic Hôtel Hermitage Monte-Carlo via a private underground passageway, the Thermes Marins Monte-Carlo serves as the flagship wellness facility for the palace hotel’s clientele, offering integrated access to seawater-based therapies and coastal relaxation.
Spanning 6,600 square meters across four levels overlooking Port Hercule and the Mediterranean Sea, the sanctuary features a 25-meter indoor heated seawater pool alongside solarium terraces, saunas, hammams, and outdoor whirlpools. The complex draws seawater directly from offshore depths to supply its thalassotherapy hydro-circuits and pools, combining traditional marine treatments with modern preventative health and fitness programming.

Guests staying at the Belle Époque property maintain direct internal access to the facility's full range of services, including custom thermal hydro-treatments, panoramic fitness facilities, and specialized wellness consultations.
