Hot Springs State Park
Northeast edge of Thermopolis

Hot Springs State Park In the foreground across the river are Rainbow terraces, formed of mineral deposits from the world’s largest mineral hot spring. Algae forms the multicolored of the terraces. The spring flows 18,600,000 gallons every 24 hours, temperature 135 degrees Fahrenheit. The site was a former Indian shrine where Shoshones and Arapahos bathed and held ceremonials. Washakie, chief of the Shoshones, led the tribes in signing a treaty which gave the healing waters to the Great White in Washington. An Indian pageant annually depicts the gift of these waters. Now a state park, with buffalo herd, picnic areas, playgrounds, swimming pools, tourist accommodations. No entrance fee.
