## About Radium Hot Springs (Colorado)

Radium Hot Springs flows at approximately 104°F on Colorado State Wildlife property, situated roughly halfway between Kremmling and State Bridge as a moderate-temperature thermal source within the Radium State Wildlife Area's Blacktail Unit.

The spring emerges from Colorado Parks and Wildlife-managed land at 6,868 feet elevation. The surrounding landscape features mixed piñon-juniper and ponderosa pine forest characteristic of this Grand County valley environment. The thermal feature sits at a short walk of 435 feet from the nearest access point through open woodland.

This thermal system displays near-neutral pH of 7.7 with moderate total dissolved solids of 240 mg/L, suggesting interaction with crustal fluids at moderate depths. The spring name derives from historical recognition of radium presence, though measured radium levels remain minimal. State wildlife management includes this thermal feature among diverse geothermal resources.

A 435-foot walk from parking areas provides easy access during most seasons. Radium Recreation Area lies 1.9 kilometers away and accommodates overnight camping. The wildlife area remains open year-round, though winter conditions on access roads can present navigation challenges requiring suitable vehicle preparation.
