Must see · Hot Spring · State Park
Hot Springs State Park is a public recreation area in Thermopolis, Wyoming, known for its hot springs, which flow at a constant temperature of 135° Fahrenheit. The state park offers free bathing at the State Bath House, where temperatures are moderated to a therapeutic 104°F. The petroglyph site at Legend Rock, some 25 miles away, is also part of the park. The park is managed by the Wyoming Division of State Parks and Historic Sites.
The land on which the state park sits was a cession agreement and the ceded portion was purchased from the Eastern Shoshone by the federal government in 1896, when Indian Inspector James McLaughlin negotiated a purchase price of $60,000 for a 100-square-mile portion of the Shoshone reservation. After a one-square-mile section of that land was released to the state in 1897, it became Wyoming's first state park, known at that time as Big Horn Hot Springs State Reserve.
The park features a managed herd of bison, a suspension foot bridge across the Big Horn River, picnic shelters, boat docks, flower gardens, and terraces made of naturally forming travertine (calcium carbonate) caused by a flowing mineral hot spring. The park area encompasses commercial hotels and several state-run and privately operated entities including the Gottsche Rehabilitation Center, Hot Springs County Memorial Hospital, the historic Callaghan Apartments/Plaza Hotel, the Star Plunge waterpark, the Tepee Pools waterpark, and the Wyoming Pioneer Home, a state-run, assisted-living facility.

  • This park is beautiful. There are two pay concessions that offer Hot Springs swimming and hot tub’s. But the state run hot springs pools are free. They have clean bathrooms and showers. We really enjoyed visiting this beautiful park.
  • Free 20 Minute Soak! Bath house pools - One inside & one outside, very comfortable temperatures. Adjoining springs have all day use for a fee. Quiet place in September!
