Hot Springs State Park


This unique natural wonderland is one of Wyoming’s most relaxing attractions. Each day, more than 8,000 gallons of mineral-rich water flow in at a constant temperature of 135 degrees. The site was preserved thanks to an 1896 treaty between Shoshone Chief Washakie, Arapaho Chief Sharp Nose, and the U.S. government, stipulating that the springs would always have free access.

The treaty has endured: the park is still free to the public, as is its bathhouse, where you can take a therapeutic soak in 104-degree indoor or outdoor pools (bring your own swimsuits and towels, or rent them on site). There are also 6.2 miles of trails; comfort stations; boat docks; picnic shelters; the large Big Spring pool; and a swinging suspension footbridge that offers the best views of the fascinating terrain.
