Hot Spring
This thermal spring in Lake Mead National Recreation Area flows at approximately 95°F within the dramatic canyon country where the Colorado River created America's largest reservoir. Located at just 700 feet elevation, the spring offers exceptional geological and hydrological context.
The spring requires a substantial hike of approximately 7,120 feet from the nearest road across rugged desert terrain within Lake Mead's canyon system. The landscape showcases the Colorado River's immense power in carving through colorful rock formations. Water flows through arid desert where annual precipitation barely reaches 6 inches.
The spring lies within Lake Mead National Recreation Area with open public access on National Park Service lands. However, the long hiking approach and remote canyon location mean few visitors reach this thermal feature. Summer heat intensifies the desert experience substantially. Bring ample water for the return hike.
This thermal spring emerges from terrain shaped by the Colorado River's geological work and regional geothermal systems. The USGS-documented temperature of 34.8°C reflects shallow geothermal circulation in the basin-and-range province. The location near Hoover Dam connects the spring to modern water resource history.
The water at Hot Spring is slightly alkaline (pH 8.2) with 2790 mg/L total dissolved solids. It is notably rich in calcium (may support bone density and joint health), sodium (supports circulation and skin hydration), and sulfate (traditionally used for skin conditions and inflammation).
