Wyoming Hot Springs

The largest hot spring in the United States and the third largest in the world, Grand Prismatic is Yellowstone's most photographed feature. Its vivid rainbow of colors—deep blue center ringed by orange, yellow, and green bands of thermophilic bacteria—creates one of nature's most extraordinary visual displays.

One of Yellowstone's most remote soakable hot springs, requiring a multi-day backcountry trek through the Bechler region. Hot water cascades down a forested hillside into the Ferris Fork of the Bechler River, creating a series of warm pools in a pristine wilderness setting that few visitors ever reach.

A massive complex of terraced travertine hot springs at Yellowstone's northern entrance, where superheated water deposits tons of limestone daily to build ever-changing white and orange terraces. The boardwalk system winds through steaming formations that have been reshaping themselves for thousands of years.

Where a geothermal hot spring meets the cold Gardner River inside Yellowstone National Park. Bathers find their perfect temperature by positioning between the hot and cold water flows. A unique soaking experience in America's first national park.

Home to the world's largest single mineral hot spring, Big Spring flows at over 3.6 million gallons per day and feeds a free public bathhouse operated by the State of Wyoming — the only state park in America offering free hot spring soaking. Vivid rainbow-colored travertine terraces cascade down the hillside near the Big Horn River, rivaling those at Yellowstone. A bison herd roams the park grounds, adding to the quintessentially Western experience.

A Forest Service-maintained concrete pool fed by a 112°F geothermal spring at the end of a scenic 10-mile drive (or winter cross-country ski/snowmobile) into the Gros Ventre Mountains near Jackson Hole. The pool sits in a dramatic granite-walled canyon surrounded by towering peaks, and the temperature varies naturally with the seasons. The journey to reach Granite Hot Springs is as rewarding as the soak itself.

A recently revitalized community hot spring along the Snake River south of Jackson, featuring a large main soaking pool and a separate cool plunge pool with stunning Teton views. Originally a beloved local swimming hole for decades, Astoria was restored and reopened as a nonprofit community facility with modern amenities while preserving its unpretentious local character. The combination of affordable soaking, Snake River access, and Teton panoramas makes it a Jackson Hole favorite.

A beloved southern Wyoming institution where the town of Saratoga maintains a free public mineral pool called the Hobo Pool right on the banks of the North Platte River, fed by a naturally heated 117°F source. The adjacent resort offers private teepee-covered tubs, but the free riverside pool is the real draw — locals and travelers alike soak under the stars while listening to the river flow past. The mineral water has been renowned since the days of the Ute and Arapaho peoples.

Located just south of Yellowstone National Park near Flagg Ranch, Huckleberry features multiple warm pools in a marshy meadow along Polecat Creek with views of the Teton Range. The gentle 100°F temperature and easy half-mile trail make it accessible to most visitors, though the boggy terrain can be muddy. Bear awareness is essential in this prime grizzly habitat where the Greater Yellowstone Ecosystem meets Grand Teton country.
