Norris Hot Springs
A single 40-by-40-foot pool built of locally milled fir planks laid over artesian springs, about 35 miles west of Bozeman. The pool is drained every night and refills with fresh water; no chemicals are used, and temperatures run below 100F in summer and up to 106F in winter. A cafe, saloon and frequent live music share the site, with a summer campground next door.

Sleeping Buffalo Hot Springs & Resort
A Hi-Line resort just off US 2, 17 miles east of Malta, that began in the late 1920s as the American Legion Health Resort. A 3,200-ft artesian well feeds a 60 x 80 ft indoor pool (about 92F), a 128 x 60 ft outdoor pool added in 2025 (95-100F), hot tubs and a 48F cold plunge, all non-chlorinated and flow-through. Cabins, suites, an RV park, a steakhouse and a saloon are on site, with Nelson Reservoir across the road.

Spa Hot Springs Motel & Tenderfoot Cabins
A motel on Main Street in White Sulphur Springs with three mineral pools: a new outdoor pool at about 103F, an older outdoor pool at 98F and an indoor pool at 105F. All three are drained and cleaned every night and refilled without added chemicals. The motel has 41 rooms and 12 cabins across the street, and guests swim free.

Wild Horse Hot Springs
A rustic, off-grid soaking site outside the town of Hot Springs with communal outdoor plunges fed by the Mother Dragon artesian well. The plunges are chemical-free and continuously refreshed, and soakers can open hot-water valves to adjust the temperature. Rustic cabins and tipis share a bathhouse; there is no restaurant, so bring food and water.

Yellowstone Hot Springs
A soaking complex on the Yellowstone River at Corwin Springs, eight miles north of the park's North Entrance. Three flow-through mineral pools include a 103-105F hot pool, a 98-100F main pool with alcoves and a 60-65F cold plunge. Cabins and suites are available year-round, RV and tent sites May to October, and the site is alcohol-, tobacco- and pet-free.
