Warfield Hot Spring
Warfield Hot Spring, also known as Frenchman's Hot Springs or Frenchman's Bend Hot Springs, surfaces at 124°F along Warm Springs Creek in the Sawtooth National Forest. At 6,250 feet elevation, it features three wide, shallow pools with rock walls and sand-and-gravel bottoms, just 31 meters from the road.
The spring sits in a narrow mountain valley along Warm Springs Creek, 11 miles west of Ketchum in Blaine County. At 6,250 feet, the surrounding slopes are covered in mixed conifer forest with aspen groves along the creek. The Pioneer Mountains rise to the south and the Smoky Mountains to the west. Annual snowfall averages 108 inches, and the average annual air temperature is 39.4°F. The creek corridor provides riparian habitat with willows and cottonwoods framing the thermal pools.
The spring carries three names reflecting its layered past. The Warfield designation appears in USGS records, while local usage favors Frenchman's Hot Springs, suggesting a French-speaking trapper or settler worked the drainage. The springs have been informally developed with rock-walled soaking pools. Easley Campground, 15.8 km east on Highway 75, has served as a base camp for soakers and anglers in the Big Wood River corridor for decades.
Roadside access makes this a year-round destination, though winter snowpack may require chains or four-wheel drive on the approach road. Water at 124°F is hot but manageable in the downstream pools where creek water mixes in. Ketchum, 11 miles east, provides full services including gear shops, dining, and lodging. Easley Campground is reservable and sits at 6,800 feet. The Harriman Trail passes nearby for combined soaking and hiking trips.
