With 40,000 square feet and 30 treatment rooms, the Wine Country's largest spa provides every amenity you could possibly want, including pools and hot tubs fed by local thermal springs. Although the place bustles with patrons in summer and on some weekends, the vibe is always soothing. The signature bathing ritual includes an exfoliating shower, dips in two mineral-water soaking pools, an herbal steam, a dry sauna, and cool-down showers. Other popular treatments include
the warm ginger-oil float, which involves relaxation in a weightless environment, and the perennially popular caviar facial. The most requested room among couples is outfitted with a two-person copper bathtub.
