Ancient geothermal springs flow beneath the grounds of Fairmont Sonoma Mission Inn & Spa, feeding five naturally heated mineral pools that have drawn wellness seekers to this Sonoma Valley retreat for over a century. Guests can soak in the Roman-style Bathhouse—featuring a halotherapy sauna, geothermal pools, and aromatherapy steam room—or spend the day at the main resort pool shaded by towering redwoods. Fairmont Spa's treatments and farm-to-table dining at Santé complete the picture.
