Willow Stream Spa

Welcome to Relaxation

Willow Stream Spa at Fairmont Sonoma Mission Inn is now fully re-opened, offering our most popular 60-minute Spa experiences and Salon services in private indoor treatment areas.

Geo-thermal mineral pools at Wine Country’s premier destination resort spa offer relaxation and rejuvenation (for both registered resort guests and for day spa access) daily from 9am - 6pm. The Sonoma Store as well as the Spa Café will be open during regular pool hours.

Willow Stream Spa’s enviable location atop an ancient thermal mineral spring makes this a spectacularly unique wellness facility that boasts 3 outdoor thermal mineral pools ranging from 92 to 102 degrees.  The Roman style bathhouse is home to the famed Bathing Ritual where guests are encouraged to “Take the Waters” for health and vigor. This includes two further soaking pools as well as a Halotherapy Sauna and an Aromatherapy Steam Room.

Historically revered by Native Americans for its healing power, the ancient thermal mineral spring, flowing from 1,100 feet (335 meters) below the resort contains 27 different minerals and arrives at the surface at 130 degrees. Outdoor terrace seating is reserved for spa service guests as well as those utilizing day access.

We recommend that you arrive 30 minutes before your first scheduled appointment to relax, familiarize yourself with the facilities, and experience our bathing ritual. Please note that all treatments end on time, regardless of start time. Please leave jewelry and other valuables in your room safe or the hotel safe.
