Tucked away in the heart of Sonoma Valley, the historic Boyes Hot Springs have drawn visitors seeking rest and renewal for generations. Set above these ancient thermal mineral waters, Fairmont Spa offers a serene wellness retreat anchored by five geothermal mineral pools and a striking Roman-inspired bathhouse.
Rooted in the natural rhythms of Wine Country, the spa experience blends time-honored healing traditions with thoughtfully curated treatments designed to restore balance and encourage relaxation. From soothing thermal soaks to deeply restorative rituals, each moment invites guests to slow down, unwind, and reconnect—both physically and mentally.
The adults-only spa welcomes resort guests as well as day visitors, offering a peaceful escape and a rare opportunity to experience Sonoma’s storied hot springs in an atmosphere of refined tranquility.
