Fountain of Youth RV Park in Thermopolis draws its hot spring water from the same mineral aquifer that feeds Big Spring, one of the world's most productive geothermal springs. The park maintains an outdoor mineral pool reaching around 40°C open to both registered RV guests and day visitors. Surrounded by the high desert landscape of central Wyoming, it offers a relaxed alternative to the busier state park bath houses while still delivering the same sulfur-tinged mineral waters that have drawn health seekers to Thermopolis for over a century.
