These are the Idaho hot springs you earn. This collection gathers soaks reached by hiking in, from a few trail miles to full backpacking trips, most with camping near the pools at the end of the walk. The effort is the filter: the farther you walk, the quieter the water. Trail conditions, river crossings and seasonal closures live in each listing, so plan the hike as carefully as the soak.
Sulphur Creek Hot Spring is a documented thermal spring on Sulphur Creek, the 18-mile tributary that joins the Middle Fork of the Salmon River at Dagger Falls, deep inside the Frank Church River of No Return Wilderness. It exists in the federal record as an entry in the USGS thermal springs inventory, which plots it…
Pistol Creek Hot Springs is a documented thermal spring on Pistol Creek, a tributary of the Middle Fork of the Salmon River, deep inside the Frank Church River of No Return Wilderness in Valley County. It exists in the federal record as an entry in the USGS thermal springs inventory, which plots it at 115°F…
Trail Flat Hot Springs is a small, undeveloped soak at the edge of the Middle Fork of the Salmon River, at Trail Flat camp in the Frank Church River of No Return Wilderness. It is the first hot spring on the river below the Boundary Creek launch, and for a lot of Middle Fork trips…
Sheepeater Hot Springs is a cluster of undeveloped soaking pools on a high terrace above the Middle Fork of the Salmon River, at river mile 13 in the Frank Church River of No Return Wilderness. It is the second hot spring on the river below the Boundary Creek launch, and one of the most reliable:…
Bull Creek Hot Springs is an undeveloped spring on Bull Creek, a tributary of the Middle Fork Payette River, in the roadless backcountry of the Boise National Forest north of Crouch. It is a named USGS feature, prominent enough that the 7.5-minute topo map covering it is the Bull Creek Hot Springs quadrangle. What it…
Plan a backpacking trip to Idaho backcountry hot springs: pack lists, area and seasonal research, Leave No Trace, campsite and soaking etiquette, and safety warnings.
Lil Dipper Hot Springs is a small hot spring on the Middle Fork Payette River trail in the Boise National Forest north of Crouch, Idaho — you’ll pass it on the hike to Moondipper and Pine Burl. The old listing is honest about it: with low flow and only upper-90s temperatures, Lil Dipper is a landmark on the way to better soaks, not a soak itself.
Skillern Hot Springs is one of the finest backcountry soaks in the Smoky Mountains: a solid rock-walled, waterfall-fed pool with a log dam, reached by a roughly 2-hour hike in the Sawtooth National Forest in the Fairfield/Featherville area. Crystal-clear water at 100–106°F, a trailhead campground, and seasonal riverside pools below make it worth every step.
Pine Burl Hot Springs is a single rock-walled pool at the end of a 2-mile hike in the Boise National Forest north of Crouch, on the Middle Fork of the Payette River trail — past both Moondipper and Lil Dipper. It’s generally the best soak of the three on this creek, with one quirk: its temperature, usually a near-perfect 101–103°F, can vary dramatically.
Moondipper Hot Springs is a single rock-walled pool on a 2-mile hike along the Middle Fork of the Payette River from the Boiling Springs Guard Station, in the Boise National Forest. It’s the lesser sibling of nearby Pine Burl — a good soak in its narrow window, because Moondipper only works when there’s enough cold creek water to tame a source that runs far too hot on its own.
Lightfoot Hot Springs is a neglected, rarely visited soak about 20 miles from Featherville in the Sawtooth National Forest — and it starts with a trap for the unwary: the signed pools beside the road are a decoy. The real Lightfoot pools lie on the far side of the South Fork Boise River, reached by a dirt forest road, a pack bridge, and a short hike (or a river ford, not advised during spring runoff). What waits there, on the only documented visit, was underwhelming: stagnant, dirt-lined pools in a weed-infested area, badly in need of reconstruction.
Deadwood Hot Springs is a true jewel of the Boise National Forest: three pools — two small, one a large cliff-hanger soaker on a granite ledge above Warm Springs Creek — at the end of an approximately 3-mile hike from Deadwood Reservoir, northwest of Lowman, Idaho. The sources emerge through fissures all over a huge granite outcropping rising straight out of the creek.
Upper Loon Hot Springs is a complex of four separate hot spring sources strung along the Loon Creek Trail in the Frank Church–River of No Return Wilderness, passed in consecutive order as you trek up Loon Creek toward Warm Springs Creek. With everything from a two-person soaker to a 10–15 person pool fed by a hot waterfall, it’s one of the finest backpacking soaks in Idaho — reachable only in a short summer-to-fall window.
Tenmile Hot Springs is a set of user-built rock pools in the Boise National Forest in the Lowman area, in a grassy, picturesque setting with excellent camping and hiking around it. The honest catch is in the pools themselves: the water temperature is perfect, but the pools are mucky — loaded with silt and algae — and a good soak here takes patience and elbow grease.
Owen Cabin Hot Springs is a historic hot spring site on Loon Creek in the Frank Church–River of No Return Wilderness, just beyond Upper Loon Hot Springs — and, honestly, a place to visit for the history and the meadow rather than the soak. Only the outlines of the old rock-walled pools remain where the spring’s outflow meets Loon Creek.
Dagger Creek Hot Springs is a set of three rock-walled pools above the mouth of Dagger Creek, near Dagger Falls on the Middle Fork of the Salmon River in the Salmon-Challis National Forest. It is a beautiful corner of Idaho — but go in with calibrated expectations: the pools are silty, and the one documented visit was swarmed by biting horse and deer flies.
Bear Valley Hot Springs is a string of stellar soaking pools of all shapes and sizes along Bear Valley Creek in the Frank Church–River of No Return Wilderness, northwest of Lowman in the Boise National Forest. Reaching them takes a moderate hike and a river ford — and the reward is one of the highest-rated wilderness soaks in Idaho, fed by multiple sources in a spectacular backcountry setting.
Buckhorn Hot Springs is a hard-to-find soak on Buckhorn Creek in the Payette National Forest, in the Warm Lake/Yellow Pine area. A gradually inclined 5-mile hike — gaining more than 1,000 feet on an overgrown old forest road — keeps use low at a meadow- and forest-edged spring with a rock-walled pool and a stand-up hot shower.
Secesh Hot Springs is a chain of rock pools perched high above the Secesh River in the Payette National Forest, in the Warren area northeast of McCall. Reaching them takes a river ford followed by a quarter-mile, near-vertical scramble — and the payoff is some of the softest hot springs water in Idaho, in a place that sees very little use.
Council Mountain Hot Springs — also known as Laurel Hot Springs — is a rock-walled soak in the Payette National Forest near Council, Idaho, reached by a forest trail climbing the side of Council Mountain. The single pool runs about 96–98°F, warming as the season progresses, and sees only moderate use.
Stuart Hot Springs is a little-known wilderness soak at the edge of a grassy meadow in the Selway-Bitterroot Wilderness, in the Lochsa Ranger District of North-Central Idaho. It is reachable only at the end of a long, arduous, multiday trip involving multiple river fords — one of the most committing hot springs approaches in the state.
Stanley Hot Springs is a chain of rock- and log-dammed pools in the ancient forest of the Selway-Bitterroot Wilderness, more than 20 miles east of Lowell, Idaho — not to be confused with the town of Stanley in the Sawtooths. The pools sit at the end of a grueling 6-mile hike on a rough trail, and the reward is a deep, wide soaker in one of the wildest settings in North-Central Idaho.
Prospector Hot Springs is one of the least-documented soaks in Idaho: a remote hot spring deep in the Selway-Bitterroot Wilderness, in the Lochsa Ranger District of North-Central Idaho. Almost nothing is published about the pools themselves — reaching them is a hard-to-find, multiday backcountry trip in its own right.
Goldbug Hot Springs is a hike-in natural hot springs in the Salmon-Challis National Forest south of Salmon, Idaho, reached by a roughly 2-mile trail with a steep final half-mile. Rock-walled pools and hot waterfalls line the creek at about 6,200 feet elevation.
