The 10 Best Hot Springs in Idaho
Idaho has more soakable wild hot springs than any state in the country, and its best run the full range: waterfall-fed roadside pools, a river you ford for solitude, and a 1919 state-run pool town. Each pick was researched against current forest, BLM, and operator sources.
The Highway 21 corridor between Boise and Stanley alone carries three of these — the best hot-spring road trip in America.
Kirkham: a hot waterfall spilling into Payette riverside pools, straight off Highway 21. The gateway Idaho soak — go fall through spring to dodge both crowds and high water.

Directions, season & rules for Goldbug Hot Spring →Jerry Johnson: cedar forest, a suspension bridge over the Lochsa, and terraced creek pools. Day-use only and patrolled — the rangers mean the 8pm close.
Directions, season & rules for Jerry Johnson Hot Springs →Burgdorf: an 1870s resort of log cabins and gravel-bottomed pools at 6,100 feet, reservation-only — and snowmobile-only all winter, which is the version worth planning for.
Directions, season & rules for Burgdorf Hot Springs →Trail Creek: boulder pools with a swing-away hot pipe, a hundred steep yards below the road. The locals' winter soak — bring microspikes for the icy scramble.
Directions, season & rules for Trail Creek Hot Spring →Sunbeam: rock pools in the Salmon River itself below a 1937 CCC bathhouse, eleven miles from Stanley. Late summer, low water, mountain light.
Directions, season & rules for Sunbeam Hot Springs →Bonneville: creekside pools and a cast-iron tub in its own soak shack, a quarter-mile stroll from the campground. Midsummer's busiest backcountry soak.
Directions, season & rules for Bonneville Hot Springs →Rocky Canyon: ford the Middle Fork Payette (rope provided) and the cascading pools on the far bank are yours. Late-summer water levels only — the crossing is the gatekeeper.
Directions, season & rules for Rocky Canyon Hot Springs →Lava Hot Springs: five terraced mineral pools run by a state foundation since 1919, odor-free and open 363 days. The polished end of the Idaho spectrum.
Directions, season & rules for Lava Hot Springs →Zims: the Nez Perce Tribe's family plunge near New Meadows — soaking pool, big warm swimmer, snack bar. The easy one, and that's the compliment.
