At 108 degrees Fahrenheit and nearly three miles from the nearest road, Snowshoe Johnson's Hot Spring in Idaho's Salmon National Forest demands real effort to reach. The payoff is a genuine backcountry soak at 5,472 feet elevation with few other visitors around.

Location

The hike in from Hoodoo Meadows Road crosses terrain that receives over nine feet of snow annually, so timing matters. Custer County's high country opens into meadows and conifer stands as the trail gains elevation. The spring itself emerges in a setting where the only sounds are wind through lodgepole pines and moving water. At 66 degrees above the average annual air temperature of 42 degrees Fahrenheit, the thermal contrast against mountain air feels especially pronounced on cold mornings.

This is a hike-in destination requiring roughly 2.7 miles of trail from Hoodoo Meadows Road. Carry everything needed for a full day. The area is snowbound well into June most years given the 110 inches of annual snowfall. No facilities exist at the spring. GPS coordinates are essential as signage is limited in this part of the forest.

History of Snowshoe Johnsons Hot Spring

Named for a local character from the settlement era, this spring sits within a landscape shaped by the Idaho Batholith, the massive granite intrusion responsible for heating groundwater across central Idaho. The Salmon National Forest holds dozens of thermal features, but Snowshoe Johnson's remote location has kept it relatively unchanged. Federal management under the Forest Service maintains the area with minimal development.
