Wilbur Hot Springs, formerly known as Simmons Hot Springs, is a naturally occurring historic hot spring approximately 22 miles west of Williams, Colusa County, in northern California. It is about 2 hours by car northeast of the San Francisco Bay Area. It was developed as a spa in the 19th century, and since its acquisition in the 1970s by therapist Richard Louis Miller, has been operated as a spa resort and personal retreat. The adjacent valley was added to the property as a nature reserve protected by covenant.
