Downata Hot Springs
Downata Hot Springs emerges at 109 degrees Fahrenheit in the high valleys of Oneida County near Malad City, southeastern Idaho's pocket of geothermal activity along the Utah border. Its calcium-magnesium chemistry stands apart from the sodium-dominated springs found across most of central Idaho, reflecting a different geological setting entirely.
The spring sits at 4,760 feet in rolling ranch country where irrigated fields and dry-farmed grain alternate with sagebrush flats. The Bannock Range rises to the east, and the landscape feels more Great Basin than mountain Idaho. Annual precipitation of just under 20 inches keeps the hills brown through summer, while winter brings moderate snow. South Downata Road passes within about 800 feet, and the surrounding area is agricultural rather than wild, with fences and ranch buildings visible nearby.
The 109-degree temperature is suitable for soaking where accessible. A short walk of about 800 feet from South Downata Road reaches the spring. Malad Summit Guard Station, a reservable Forest Service cabin about 9.5 miles north off I-15, offers rustic overnight accommodation. Malad City provides basic services. The area is accessible year-round, though winter conditions require appropriate vehicles on secondary roads.
Downata's water chemistry tells a different geological story than Idaho's batholith springs. Calcium at 43 mg/L and magnesium at 15 mg/L dominate over sodium at 20 mg/L, indicating circulation through carbonate rock rather than granite. The slightly acidic pH of 6.7 and total dissolved solids of 266 mg/L support this interpretation. Iron at 40 micrograms per liter adds a faint rust tint. The spring sits within the Basin and Range Province, where extensional faulting creates pathways for geothermally heated water.
The water at Downata Hot Springs is slightly acidic (pH 6.7) with 266 mg/L total dissolved solids.

Overview Malad Summit Guard Station is located 14 miles north of Malad, Idaho on Malad Pass just off I-15. The rustic one-room cabin is in a forested setting in narrow Mill Creek Drainage, and offers a secluded retreat on fenced acreage surrounded by scenic high country views. The original guard station was established in 1908, but was replaced by the existing cabin in 1934. The cabin is accessible by car when there is no snow. Guests should be prepared in snowy conditions to ski, snowshoe...
