The story of The Fairmont Sonoma Mission Inn & Spa dates back to the Native Americans who were the first to discover the natural underground hot mineral waters. This site was considered a sacred healing ground for generations. In 1895, Captain H.E. Boyes acquired the property and struck 112 degree water while drilling a well. Within five years, he had built the Boyes Hot Springs Hotel on the site of the current property. Shortly thereafter San Franciscans were arriving to 'take the waters' at the finest hot mineral water resort in California.
