CALMING HOT STONE MASSAGE - a Clarins Miraval Creation! A guest favorite at Miraval, we’ve designed this new treatment to combine the grounding effects of hot stones with the power of botanicals. Heat from the smooth basalt stones comforts and calms the mind as it renders muscles more limber and open to manipulation by the therapist. Your skin more readily accepts the professional-grade, antioxidant packed essential oils used in the massage, and your mind and body emerge in balance.
