Worswick Hot Springs registers 180°F, making it one of Idaho's hottest publicly accessible thermal features. Located on Sawtooth National Forest land at 6,100 feet elevation in Camas County, the spring sits a short 191-foot walk from Carrie Creek Road near Fairfield. Water chemistry shows high alkalinity at pH 9.0 with sodium-dominant mineral content.
The spring occupies a high mountain valley in the Sawtooth National Forest, surrounded by sagebrush steppe and conifer-covered slopes at 6,100 feet. Annual snowfall exceeds 107 inches, and average air temperatures hover around 41°F, producing a stark 139-degree contrast between water and ambient conditions. Big Smoky Creek drains the area to the south, cutting through a broad valley floor flanked by the Soldier Mountains and the Smoky Mountains.
History of Worswick Hot Springs
The spring takes its name from an early settler family in the Camas Prairie region. Federal land records show continuous Forest Service management. No commercial development exists on site. The extreme water temperature has precluded the kind of casual soaking infrastructure seen at lower-temperature Idaho springs, leaving the feature in a largely natural state.
Summer and early fall provide the best access, as heavy snowfall closes many area roads from November through May. The 180°F water is dangerously hot and must not be entered directly. Bowns Campground, 8 km south along Big Smoky Creek, has 10 first-come, first-served sites with fire rings and seasonal water. Bring layers for cold mountain nights even in July.
