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

The iconic spa destination on Calistoga’s main street, easily identifiable by its original neon sign and vintage 1952 Buick Special parked at the curb, has attracted wellness seekers for seven decades from around the world. The spa 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 almost 70 years ago.
