Malad Warm Spring
At 77 degrees Fahrenheit, Malad Warm Spring barely qualifies as thermal, but its water chemistry tells a different story. Total dissolved solids hit 4,500 milligrams per liter with 2,100 milligrams per liter chloride and 1,200 milligrams per liter sodium, making this one of Idaho's most intensely mineralized springs despite its modest temperature.
The spring sits at 4,495 feet in Oneida County's Bear River Valley outside Malad City, surrounded by the dry ranching country of southeastern Idaho. A short walk of about 430 feet from the road leads to the source, where the mineral-heavy water leaves visible deposits along its flow path. Winters bring 51 inches of snow across the valley floor, but the spring's steady 77-degree output keeps its immediate surroundings green year-round.
Malad Warm Spring rises where deep faults along the Bear River Range allow groundwater to circulate and dissolve ancient marine sediments before surfacing. The unusually high chloride and sodium concentrations suggest contact with evaporite deposits buried beneath the valley. USGS measurements confirm 25 degrees Celsius with a slightly acidic pH of 6.5, unusual among Idaho's generally alkaline thermal waters.
Third Creek Group Site, about 6 miles northeast, offers reservable camping near Deep Creek Reservoir. The spring sits on private land, so verify current access before visiting. Malad City provides basic services. Winters here average 49 degrees annually with significant snow, so summer and early fall visits are most practical.

The water at Malad Warm Spring is slightly acidic (pH 6.5) with 4500 mg/L total dissolved solids. 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).
