Casa de Campo's new spa is refreshingly understated from the get-go. The reception, in an unfussy plaster building, has stacked-stone walls, a giant pebble sculpture, and green velvet wingback chairs. From here, the therapist leads guests past a garden with a meditation circle to seven treatment pavilions and an eighth housing a sauna, a steam room, and hot and cold whirlpools. All have cathedral ceilings, full en suite bathrooms, and a light aroma of lavender. Treatments run the gamut from facials and massages to scrubs and wraps. During the signature 100-minute Phenomenal 3D Hot Stone Massagethe exception to the understated themethe therapist places volcanic stones all over the body to create a flow of positive energy, while working out knots and kinks via long, sweeping strokes. A piece of advice: Ask the therapist to kill the musicthe incessant smooth jazz does nothing to enhance the experience.
