• Smith Cabin Hot Springs consist of 3 pools on both sides of the river
Nestled on both banks of the Middle Fork Boise River, Smith Cabin Hot Springs is a primitive soaking spot surrounded by peaceful nature. It features three pools located on either side of the river.
The first pool is just a short walk from the road. The second sits across the river a bit upstream, and the third is about 100 yards farther upstream and 20 yards away from the riverbank. To reach the second and third pools, you’ll need to ford the river—be cautious when water levels are high—or park on the opposite side and walk about a mile.
Hot mineral water flows from the source at about 143°F and can be cooled with river water. The pools, built from rocks by volunteers, are shallow and rustic. Two of the three pools sit right next to the river, but winter runoff often washes them out.
There are no amenities at this site. Because the pools are visible from the road, clothing is recommended.
