Wilbur Hot Springs, set on a private 1,600-acre nature sanctuary in the remote Coast Range foothills of Colusa County, California, is a historic sulfurous thermal retreat dating to the 1860s that has operated as a non-motorised, clothing-optional wellness sanctuary since the 1970s, attracting those seeking deep quiet and natural healing. The naturally hot sulfurous springs emerge at around 49°C and flow through stone and concrete channels into a series of indoor and outdoor pools in the century-old bathhouse, requiring no chemical treatment due to the naturally self-purifying sulfur content. The surrounding private nature reserve — with no cell service, no Wi-Fi, and no electronic entertainment permitted — creates an experience of radical disconnection that Wilbur's loyal guests prize as the true purpose of a thermal retreat.
