Before you go
- Status: Open — last verified below — confirm via Hot Springs Locator — Atlanta Hot Springs (pool specs, Frog Pond, seasonal road, Riverside CG).
- 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 104°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: None — Boise National Forest, free.
- Best time to go: Late June-early October; the pool is heavily used by locals on summer weekends — weekday mornings are quietest. Off-season it's essentially snowmobile-access only.
- Clothing reality: Swimwear required — reports note a posted 'no nudity' rule; locals use it for bathing and it's right beside the road.
- Kids: Allowed.
- Cell service: none — download maps and tell someone your plan.
- Accessibility: Roadside pullout pool — minimal walking — but reached only by very rough remote roads; uneven ground at poolside.
- Getting there is the challenge: ~95 mi of Boise NF dirt from Boise via FR 268 (Middle Fork Boise River Rd) — notorious extreme washboards, single-lane cliff stretches, aging bridges; high-clearance required, 4WD recommended in the upper canyon; allow ~3 hrs from Boise
- Seasonal access: most routes into Atlanta close Nov-May/June with snow; the Middle Fork road is the only theoretical winter route but is unplowed, narrow, no guardrails, avalanche-prone — realistically late June-Oct for vehicles, snowmobile/ski in winter
- Pool etiquette: piped hot AND cold inflows are adjustable; the bottom drain plug lets you empty/scrub and refill (~30 min) — leave it clean for the next user
- Red spider mites documented at this spring — apply repellent AFTER soaking; also reported at nearby springs (Chattanooga, Vulcan)
- No camping AT the springs (posted) — use Riverside Campground along the Middle Fork (recreation.gov mid-June-Sept, else first-come) or dispersed sites
- Source ~145F piped into the pool at ~107-110F before mixing — always check temp at the inflow; Frog Pond below is warm-swimming temp
- No cell service; Atlanta has a seasonal general store/lodges with limited hours — fuel up before leaving pavement
- Hazard: 145F source water at the inflow — test before entering
- Hazard: Long rough mountain road — washboards, cliff exposure, no cell, deaths have occurred on this road per local reports
- Hazard: Winter avalanche/closure — Nov-May effectively vehicle-inaccessible
- Hazard: Red spider mites
- Hazard: Black bears/cougars in area — secure food at campsites
About this spring
A volunteer-built rock-and-masonry soaking pool (~97-110°F) with benches and piped hot and cold water, ~1.2 miles east of the historic mining town of Atlanta along Middle Fork Boise River Road in Boise National Forest. Overflow feeds the adjacent warm 'Frog Pond' used for summer swimming. Rough washboarded roads, snow-closed most of winter. Red spider mites reported in the pool. Remote — no services.
Atlanta Hot Springs is a volunteer-built soaking pool about 1.2 miles east of Atlanta — a living ghost town and former gold-rush mining camp — along the Middle Fork Boise River Road in the Boise National Forest at ~5,400 feet. Geothermal water emerges around 140-145°F and is diverted through two pipes into a six-by-twelve-foot rock-and-masonry pool with benches, cooling to roughly 97-110°F depending on weather; the pool can be drained and refilled, giving users some temperature control. Overflow feeds the adjacent 'Frog Pond,' a large warm pond popular for summer swimming. Red spider mites have been reported in the pool.
Swimwear is recommended since the site is visible from the road, though sources describe clothing as optional rather than strictly required. Access is over long, rough forest roads requiring high-clearance 4WD; the Middle Fork Boise River Road is not plowed and the area is typically snowbound November through May, reachable then only by snowmobile, snowcat, or ski. Power Plant and Riverside campgrounds are nearby.
Directions & trailhead access
From Atlanta, follow Middle Fork Boise River Road ~1.2 mi east; the pond and pool are on the right. Atlanta is reached via long rough forest roads from Idaho City — high-clearance recommended; snow-closed Nov-May.
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.
