Woodruff Hot Spring
Woodruff Hot Spring flows at 81°F with remarkably high dissolved solids: chloride at 1,600 mg/L and sodium at 910 mg/L dominate the chemistry, producing water saltier than most Idaho thermal features by an order of magnitude. Roadside access at 59 meters from the road and 4,396 feet elevation in Oneida County makes it easy to reach.
The spring emerges in the Bear River Valley of southeastern Idaho near Malad City, where irrigated hay fields and rangeland spread across a broad, flat valley floor between the Bannock and Malad Ranges. Annual precipitation averages under 18 inches with about 44 inches of snow, creating a semi-arid continental climate. Cottonwoods and willows mark the waterways, while sagebrush covers the drier benches. The Malad River, known for its poor-tasting (hence "malade," French for sick) water, drains the valley southward.
The name Woodruff likely references Wilford Woodruff, a prominent figure in the Latter-day Saint settlement of southeastern Idaho in the late 19th century. The nearby Malad River received its French name from fur trappers who fell ill, possibly from drinking its mineral-laden water. The spring's extreme chloride and sodium concentrations mirror the regional pattern of briny subsurface waters. No commercial development has occurred at this site.
Third Creek Group Campground, 18.2 km northeast near Deep Creek Reservoir, is reservable and offers trail access and fishing. The spring's 81°F water is tepid, suitable for wading but not a true hot soak. The extremely high mineral content means the water leaves white salt deposits on skin and clothing. Low elevation and minimal snowfall make this spring accessible year-round. Bring fresh water for rinsing after contact with the mineral-heavy discharge.
Is Woodruff Hot Spring worth visiting?

The water at Woodruff Hot Spring is slightly alkaline (pH 7.3). It is notably rich in calcium (may support bone density and joint health), magnesium (known for muscle relaxation and stress relief), and sodium (supports circulation and skin hydration).
