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.
Warm Springs Creek Hot Springs is a barely used wilderness hot spring, the Sitz Bath, in Idaho’s Frank Church River of No Return Wilderness, reached by a difficult hike. Access roads are open only from about July to October, spring runoff destroys the lower pools, and the trip is best done as an overnighter with primitive camping nearby.
Shower Bath Hot Springs is a remote wilderness hot springs in the Frank Church River of No Return Wilderness, reached by a trail that follows the Narrows of Warm Springs Creek. Its rock-walled pools vary in size and temperature, and access roads are open only about July to October, leaving a short 2–3 month visiting window each year.
Marten Creek Hot Springs is one of the most remote soaks in Idaho, deep in the Selway-Bitterroot Wilderness in Idaho County. Reached only by a multiday backpack with multiple river fords, it is best attempted in mid to late summer.
