Before you go
- Status: Open — last verified below — confirm via SoakingSprings — 'Warm Springs' entry a.k.a. Devil's Faucet Hot Spring (112F, BLM Humboldt River FO, open roadside, Knott Creek Road ~224 ft).
- 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 105°F — always test the water before entering.
- Rules: Clothing policy unknown — verify locally; 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 — BLM public land.
- Best time to go: Late spring through fall; desert heat makes midsummer soaking less appealing, winter access can be muddy.
- Clothing reality: No policy — remote BLM land; clothing-optional use is customary at Nevada desert springs.
- Kids: Allowed.
- Cell service: none — download maps and tell someone your plan.
- Accessibility: Near-roadside (~200 ft); unpaved ground, no facilities at the pool itself.
- ID PREFIX IS WRONG: this spring is in NEVADA (Humboldt County), not California — id retained as assigned
- Two names: federal record 'Warm Springs' (GNIS), OSM/local name 'Devil's Faucet'
- ~112F source — at/just above the safe-soak threshold; enter slowly and find cooled edges
- Very remote: ~31 mi N of Winnemucca on US-95, then ~50 mi on NV-140 toward Denio, then county road to Knott Creek; fuel up in Winnemucca or Orovada
- A 2007 visitor noted 'a nice clear little hot pool with a dock' and mules nearby — believed it might be on private land; federal data says BLM (Humboldt River FO) — treat as open BLM but respect any posted fencing/signage
- Outhouse and dispersed/primitive camping near Onion Valley and Knott Creek reservoirs; no water/trash service
- Hazard: 112F source water — test for hot spots
- Hazard: Extreme remoteness: no fuel/cell for many miles; carry water
- Hazard: Dirt-road approach; muddy/impassable when wet
- Hazard: Ranch livestock (mules) reported on site
About this spring
Small clear hot pool (~112°F) beside Knott Creek Road in far northern Nevada near the Onion Valley Reservoir turn-off — tagged 'Devil's Faucet' on OSM while USGS records call it 'Warm Springs.' On BLM land near a ranch. NOTE: in Nevada, not California. Remote high desert, no services. Adjacent land may be private ranch — respect signage.
Devil's Faucet Hot Spring is the OpenStreetMap name for what federal records list simply as Warm Springs — a small thermal spring on BLM land administered by the Humboldt River Field Office, about 80 miles northwest of Winnemucca near the Onion Valley Reservoir turn-off in the Pine Forest Range backcountry. The GNIS entry fixes it at 41.7528°N, 118.8411°W at 4,458 feet elevation on the Alder Creek Ranch quadrangle; the water has been measured at 112°F, hot enough to demand short, careful soak sessions rather than long lounging. Knott Creek Road passes within about 75 yards, making this a roadside stop rather than a hike-in destination — a clear little pool visited chiefly by travelers heading to or from Knott Creek and Onion Valley reservoirs. The surrounding country is remote sagebrush high desert with no services; nearby ground includes ranch land, so posted signage should be respected.
Directions & trailhead access
From Winnemucca: Hwy 95 north ~31 mi, Hwy 140 west ~50 mi toward Onion Valley; roadside ~220 ft off Knott Creek Road.
Nevada geothermal context
Nevada has more hot springs per square mile than any other state — Basin and Range faulting brings deep thermal water to the surface across nearly every valley. Most sites are primitive seeps and tubs on public BLM land reached by long, unmaintained dirt roads. Carry extra water, and watch for flash floods in desert washes during storms.
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
October – April (Fall, Winter & Spring)Desert thermal zones experience high summer ambient heat. The cooler months from late autumn to early spring offer the most refreshing ambient conditions for open-air soaking.
