Before you go
- Status: Open — last verified below — confirm via Salmon-Challis NF — Horse Creek Hot Spring & Campground (official page).
- Cost: Reported free access — fees and permits can change, confirm before visiting.
- Getting there: No verified hike distance on record — confirm the route and road conditions.
- Water: Reported soak temperature 103°F — always test the water before entering.
- Rules: Reported clothing-optional; pets reported not allowed — confirm current rules.
- Conditions: check weather, fire closures, and land-manager alerts the week you go — mountain access changes seasonally.
- Reservations/permits: None — Salmon-Challis NF public land; no fee for soaking or camping.
- Best time to go: July-October; weekdays to avoid the summer RV/ATV weekend crowd. Not reachable in winter.
- Clothing reality: No official policy. Local custom: one group soaks at a time and locks the bathhouse door — inside the closed bathhouse clothing-optional is the norm; swimwear standard outside.
- Kids: Allowed.
- Cell service: none — download maps and tell someone your plan.
- Accessibility: Roadside — a short walk across a bridge to the bathhouse; manageable for most, though uneven ground and no developed ramps.
- ~36 miles of forest roads from North Fork: FR 030 west 14 mi, FR 038 north 8 mi, then FR 044 & FR 065 northwest 14 mi — allow ~2.5-3 hrs from Salmon; rough/washboarded, 'a bit sketchy' for low-clearance; carry a saw for downed trees — single route in/out
- Seasonal access only — ~6,200 ft elevation with heavy winter snow; roads effectively closed Nov-June; best window July-October
- Bathhouse sits right off the road (steps + short bridge over the runoff); interior pools ~100-104°F; source ~109°F; a cooler ~95-100°F sand/gravel pool downhill
- Free dispersed campground adjacent — vault toilets but NO potable water, tables, or fire rings; RVs and ATV/dirt-bike groups camp here in summer
- Area burned in past wildfires — limited shade; the Aug-Sep 2024 Red Rock Fire burned ~5.5 mi NW on the ID/MT border; check Salmon-Challis NF alerts for fire closures before driving in
- No fee, no reservations, first-come sites; trout fishing in Woods Creek; wilderness trailheads 4 mi west on FR 065
- Hazard: Very remote — ~3 hrs of dirt road, single access route, deadfall risk, no cell service
- Hazard: Winter snow closes access roads (6,200 ft)
- Hazard: Wildfire-affected surroundings; 2024 Red Rock Fire nearby — check for closures
- Hazard: ~109°F source water — test pools before entering
- Hazard: ATV/RV traffic on narrow roads
About this spring
Remote hot spring at ~6,100 ft near the Frank Church Wilderness border — a small open-roof bathhouse covers a bedrock pool (~102-104°F) for stargazing soaks, plus a shallower overflow pool. Dispersed USFS campground on site. ~36 mi of remote forest roads, summer-to-fall only. No potable water. Burned-tree windfall hazard.
Horse Creek's soaking centers on a small bathhouse — charred but still standing after a 2011 wildfire swept the drainage — built directly over a bedrock pool where roughly 103-104°F water bubbles up through cracks in the sandstone. The sand-bottomed pool runs about four feet deep and 102-103°F, holding around four soakers; the roof covers only the changing area, leaving the pool open to the sky for stargazing. A footbridge links the roadside pullout to the bathhouse, and the spring's runoff collects downhill in a shallower sand-and-gravel overflow pool of about 95-100°F with room for four to six.
A dispersed Forest Service campground adjoins the springs near the Frank Church-River of No Return Wilderness boundary at roughly 6,000 feet. Local custom is quirky: soakers traditionally latch the bathhouse door from inside, making it effectively one group at a time. The roughly 36 miles of forest roads are impassable in winter.
Directions & trailhead access
From North Fork: FR 030 west 14 mi, FR 038 north 8 mi, FR 044/065 northwest ~14 mi. Or from Conner, MT via Woods Creek Road ~14 mi. Seasonal access.
Idaho geothermal context
Idaho's thermal water rides the old track of the Yellowstone hotspot across the Snake River Plain and surfaces along faults in the surrounding mountains. Many of the best soaks are roadside or river-access pools inside national forests — including springs that only emerge when river levels drop. Backcountry sites demand real navigation skills and long dirt-road drives.
What a primitive site means here
Primitive springs have no facilities: no changing rooms, no trash service, often no maintained road to the pool. Expect natural rock or gravel bottoms, water temperature that varies by spot and season, and other visitors who may treat the site informally. Pack out everything you bring, test the water before entering, and leave the pool cleaner than you found it.
Best time to visit
Year-Round (Best: May – October)Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across Idaho. Late spring through autumn offers the most comfortable road access.
