The Spa at Dr. Wilkinson’s Backyard Resort & Mineral Springs

The iconic spa destination has attracted wellness seekers for seven decades from around the world. It remains the main attraction of the resort, offering the same world-renowned, mineral-rich mud bath treatments and secret-formula mud mixture of organic, local Calistoga volcanic ash perfected by Doc Wilkinson ~70 years ago. It features four renovated massage rooms, brand-new outdoor spa garden for al fresco treatments, four indoor mud baths, seven indoor and two outdoor mineral baths, cold deluge shower, and dedicated geothermal mineral pool filled with calming, varied temperature water sourced from Calistoga’s natural healing springs.
