Star Plunge
A family pool complex in Hot Springs State Park with indoor and outdoor mineral pools, water slides and a vapor cave, closed since Jan 14, 2025 after its concession agreement expired. On Jul 31, 2026 Wyoming State Parks announced a tentative settlement that would let a new long-term concessionaire reopen it, but no date has been set.

A commercial mineral-water pool complex in Hot Springs State Park with an indoor pool and water slide, an outdoor pool at 94-98°F and hot tubs up to 105°F. It also has a steam room and a cedar dry sauna. The site lists Carson Hot Springs and Jemez Hot Springs as sister properties.
Fountain of Youth RV Park
An RV park north of Thermopolis built around a large mineral pool fed by the Sacajawea Well, drilled in 1918, which flows about 1.3 million gallons a day.
