Sacajawea Hot Springs

Sacajawea Hot Springs is a seasonal batch of rock-walled pools on the banks of the South Fork of the Payette River, north of Lowman, Idaho, near the Sawtooth Lodge and the Grandjean trailhead into the Sawtooth National Recreation Area. Well known and easy to reach in the warm months, it is a soak that depends entirely on the river: the cold water is what keeps the pool temperatures in the usable range.

Owen Cabin Hot Springs

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.

Lunchbreak Warm Springs

Lunchbreak Warm Springs is a medium-sized, lukewarm — not hot — soak on the far side of the Salmon River in the White Cloud Mountains, in the Sawtooth National Recreation Area near Stanley, Idaho. A single rock-walled pool, a sandy beach, and picnic facilities make it a favorite stop for river floaters on a hot summer day.

Elkhorn Hot Springs (Boat Box)

Elkhorn Hot Springs — better known to regulars as Boat Box — is an easy-access wooden soaking box right next to Highway 75 near Stanley, Idaho, in the Sawtooth National Forest. Fill the tub, temper it with buckets of cold Salmon River water, and settle into one of the most beloved roadside dips in the Stanley area — it’s usable all year.

Dagger Creek Hot Springs

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

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.

Basin Creek Campground Hot Springs

Basin Creek Campground Hot Springs is a small set of rocky, user-built pools on Basin Creek off Highway 75 east of Stanley, Idaho — with one big asterisk: the campground it is named for was wiped out by flooding in 2006 and never rebuilt. The pools remain, with heavily silted bottoms and temperatures that fluctuate from too cool to piping hot, but plan on dispersed camping elsewhere along Highway 75.

Basin Creek Hot Springs

Basin Creek Hot Springs — also known as Cove Hot Springs — is a cluster of rocky, user-built pools along the Salmon River east of Stanley, Idaho, a short hike from the Highway 75 parking area past Basin Creek Campground. It comes with an honest caveat up front: on repeated visits over the years these pools have been found semi-submerged and too cool to soak, so treat this one as a low-water gamble rather than a sure thing.

Banbury Hot Springs

Banbury Hot Springs near Buhl, Idaho, is now owned by Miracle Hot Springs and reopened in 2026, offering a large general pool, individual private pools and lodging.
