Before you go

  • Status: Open — last verified below — confirm via BLM — Sharkey Hot Springs site page: two concrete pools, heated changing rooms, vault bathrooms, fire pit, kiosk; water natural and untreated; managed by Salmon Field Office; history (filled 1973, rebuilt/reopened 2002).
  • Cost: Reported $3/person — confirm current rates before visiting.
  • Getting there: No verified hike distance on record — confirm the route and road conditions.
  • Water: Reported soak temperature 100°F — always test the water before entering.
  • Rules: Reported clothing required; 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: Standard amenity fee: recreation.gov 'Sharkey Hot Springs Pass' (activitypass/10012013) or self-service Recreation Use Permit onsite; annual pass $20 via Salmon Field Office.
  • Best time to go: Any weekday; avoid Wednesday mornings (cleaning). Soaking under winter stars is popular — road is typically plowed to the lot.
  • Clothing reality: Swimsuits required/customary — developed family-oriented BLM facility with mixed public use; not a clothing-optional site.
  • Kids: Allowed.
  • Cell service: none — download maps and tell someone your plan.
  • Accessibility: Among the most accessible wild-ish springs: ADA concrete parking and walkways; pools have built-in steps, benches and handrails — though actual step-free water entry is unverified.
  • $3/person day-use fee for everyone 16+; under 16 free; $20 annual pass option; buy/download the recreation.gov pass BEFORE leaving Salmon — no cell service at site — or use the onsite self-service fee station
  • Closed every Wednesday morning for weekly cleaning and maintenance (community-reported; BLM cleans weekly)
  • Day-use only — no overnight camping at the site; BLM/USFS campgrounds along Hwy 28 and Salmon River nearby
  • Water is natural and UNTREATED — standard natural-water precautions
  • ~25 mi south of Salmon: Hwy 28 → 17 Mile Rd → Lemhi Rd (Old 28) → NF-185/Warm Springs Rd (Lewis & Clark Hwy) ~2 mi; gravel final stretch is plowed in winter per winter trip reports
  • Pools are modest — two 6'x10' concrete pools; site sees ~60-80 visitors/day, so holiday weekends can fill them
  • Fire pit use subject to seasonal BLM fire restrictions
  • Hazard: Untreated geothermal water (natural-source, not chlorinated)
  • Hazard: Remote winter driving on gravel road (though reportedly plowed)
  • Hazard: Limited emergency services — nearest help is Salmon ~25 mi

About this spring

BLM-developed recreation site on a sagebrush hillside above the Lemhi Valley — two large concrete soaking pools (~98-103°F), heated changing rooms, vault toilets and picnic tables. Rebuilt by BLM in 2002; also historically known as Lewis and Clark Hot Springs. Fee: $3/person (16+) via recreation.gov. No cell service — download the recreation.gov pass before leaving Salmon. Closed Wednesday mornings for cleaning. No camping.

Sharkey's two concrete pools are the latest chapter of a site with a deep soaking pedigree. The springs were a sacred place for the Agaideka — the 'salmon-eaters' — and the BLM's interpretive kiosk quotes tribal member Rozina George describing them as Puha Pah, 'medicine water.' Rancher Frank Sharkey settled beside the springs in the 1870s; Eleihu Barnes built a shanty over the water around 1890 to keep cattle out, and Tom Benedict's enclosed concrete pool in the 1920s was known locally as 'the plunge.' After the site fell into disrepair in the 1960s, the BLM filled the pool and burned the buildings in 1973 — but locals kept digging homemade tubs, and the agency rebuilt and reopened Sharkey in 2002.

The Salmon Field Office now runs a developed recreation site on the sagebrush hillside: untreated natural water in two large pools, heated changing rooms, vault bathrooms, a fire pit with seating, and open views over the Lemhi Valley.

Directions & trailhead access

From Salmon, Hwy 28 south ~17 mi to Tendoy; 17 Mile Road, then Lemhi Rd/NF-185 ~2 mi to the springs (~25 mi total).

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 developed site means here

A developed site sits between primitive and resort: improved soaking infrastructure — built tubs, decks, stairs, sometimes changing rooms or vault toilets — often run by a land trust, nonprofit, or small operator. Expect modest fees or donation requests, posted etiquette rules, and more predictable conditions than a wild pool.

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.
