Every Hot Spring

Wyoming hot springs

335 springs, hottest at the source is Black Warrior Group, Shelf Spring at 205°F. 294 are on public land.

Wyoming looks like a hot springs superpower on paper: 342 records in this directory, more than Idaho. The catch is that the large majority are inside Yellowstone National Park, where soaking in hot springs is prohibited outright, and where the famous names in this list (Grand Prismatic Spring, Morning Glory Pool, Steamboat Springs at Norris, Mammoth Hot Springs) are for walking past on a boardwalk. Strip those out and Wyoming has a short, excellent list of places to soak, anchored by a free state bathhouse in Thermopolis.

Yellowstone: look, do not soak

The park’s rule is simple and enforced: hot springs are off limits for bathing, because they are often at boiling point and because the thermal environments are fragile. The two historical exceptions are both closed as of this writing. Boiling River, where hot water met the Gardner River near Mammoth, was wrecked by the June 2022 floods and the park says swimming there is not possible. The Firehole Swim Area south of Madison Junction is listed as closed and in normal years only opens in mid-summer during posted hours. All thermal water in the park can carry organisms that cause illness. If you want to soak near Yellowstone, do it outside the gates: Montana’s Paradise Valley to the north, or Wyoming’s own sites below.

Where you can soak

Thermopolis and Hot Springs State Park. The Big Spring at Thermopolis pours more than 1.8 million gallons a day over the terraces above the Bighorn River at a constant 128°F. When the Eastern Shoshone and Northern Arapaho sold the springs to the federal government in 1896, Chief Washakie’s condition was that the water would always be free to the public, and the State Bath House still delivers on that: it is a free public facility with water held at 104°F for soaking. Two commercial plunges stand next door with slides and larger pools, and the park has a suspension footbridge over the river, a bison herd that staff feed on winter mornings, and the Thermopolis Hot Springs source that this directory records at 133°F. It is open year-round and is the best family soak in the state.

Jackson Hole and the Hoback. Granite Hot Springs sits at the end of Granite Creek Road about 34 miles south of Jackson on the Bridger-Teton National Forest. It is a developed concrete pool run under Forest Service oversight with a cash day-use fee, open roughly late May through October by car and then from early December into March by snowmobile, dogsled, ski or fat bike only. Granite Falls Hot Springs is the primitive seep below the falls just down the creek. Inside Grand Teton National Park, Kelly Warm Springs is a shallow, lukewarm pond that tested positive for Naegleria fowleri in 2016; the park’s advice is to keep water out of your nose, and most locals no longer get in.

Saratoga and the North Platte. Hobo Hot Pool in the town of Saratoga is free, open 24 hours a day and maintained for the public, with the main pool at roughly 101°F to 110°F and the “Lobster Pot” end around 120°F. Rock-lined seeps behind it trap hot runoff along the North Platte River so you can alternate between the pool and the river. The Saratoga Hot Springs entry in this directory, at 129°F, is the source. The town also has a resort with its own pools.

Elsewhere. The directory also records Alcova Hot Springs near Casper (129°F), Auburn Hot Springs in Star Valley near the Idaho line (144°F) and Kendall Warm Spring in the upper Green River country, but none of these is a developed public soak, and the two hotter ones are not safe to enter at the source. Check ownership and current conditions before visiting any of them.

When to go

Thermopolis and Saratoga are year-round, and winter is their best season: dry cold air, steam off the water, and no crowds. Granite is a two-season site with a spring shutdown while the road thaws; the winter snowmobile approach from the Granite Creek parking area is a day out in itself. Check the park’s road status before a winter trip to Yellowstone’s thermal basins; most interior roads are closed to cars for the winter.

Etiquette and safety

  • In Yellowstone, stay on the boardwalks and never touch hydrothermal water. The park’s own warning is blunt: it can scald you.
  • At free public pools, the courtesy is short soaks when others are waiting, no glass, no soap and no alcohol. Hobo Pool has no attendant and depends on users keeping it clean.
  • Keep your head above water in warm, still ponds such as Kelly. Wyoming is not immune to amoeba.
  • Granite is cash only and remote. Carry your own water, and in winter plan for the trip to take much longer than the mileage suggests.
  • Watch for wildlife. Hot Springs State Park has bison on the loose; view them from your vehicle.

Practical logistics

Thermopolis has motels and campgrounds and sits between Cody and Casper, so it fits a loop through the Bighorn Basin. Jackson has everything but is expensive; Pinedale is the cheaper base for the Hoback side. Saratoga, south of Interstate 80 in Carbon County, makes a good overnight between the Front Range and the parks. For Yellowstone, book lodging months ahead and soak on the Montana side at Gardiner or Chico.
