Iron Mountain Hot Springs
Iron Mountain Hot Springs occupies the banks of the Colorado River in Glenwood Springs at 5,740 feet elevation, where a developed therapeutic resort harnesses natural thermal waters with extremely high mineral content and alkaline chemistry.
The spring emerges on the riverbank, separated from the adjacent road by minimal distance. The Colorado River provides a dramatic backdrop to the resort facilities that capture and distribute the thermal water. The landscape reflects Glenwood Canyon's characteristic geology and the presence of river recreation activities nearby.
This is a fee-based developed resort facility requiring admission. Access is straightforward, just 39 feet from the road. The river location makes it accessible year-round at lower elevation, though summer remains the most popular season. Advanced reservations are recommended, especially on weekends.
