Splashland Hot Springs
Splashland Hot Springs reaches 40.5 degrees Celsius (105 degrees Fahrenheit) at just 13 meters from a gravel road near Alamosa East. This roadside spring sits in Colorado's San Luis Valley at 7,543 feet elevation, providing easy access to geothermal water in high desert terrain.
The spring emerges in sparse, wind-swept country characteristic of the San Luis Valley's vast open plateaus. Sagebrush and short grasses dominate the landscape, with commanding views of surrounding mountains. The mineral-rich water carries a sodium-bicarbonate signature with pH of 8.3, creating an alkaline thermal pool.
Splashland Hot Springs likely takes its name from recreational use of the spring's thermal waters. The spring's chemistry reflects passage through deep aquifers, accumulating sodium and bicarbonate as water circulates beneath the high plateau. Geothermal heating in this region is sustained by the valley's active geothermal gradient.
Roadside access via gravel road makes this spring readily available. Winter snowfall of 26 inches annually may create access challenges November through March. Best visits occur May through October. Bring wind protection, as the exposed location experiences strong prevailing westerly winds year-round.
