Arrowhead Springs, Waterman Hot Spr
Arrowhead Springs and Waterman Hot Springs discharge at 194°F (90°C) in the San Bernardino Mountains, among Southern California's hottest springs, with thermal water running 130 degrees above ambient temperature.
The springs emerge roadside at 1,883 feet elevation in mountain terrain characterized by ponderosa pine and mixed conifer forest. The high thermal output creates visible steam even in cool months. The mountainous setting offers cooler air than surrounding lowlands, though winter brings occasional snow at this elevation.
These springs developed within the San Bernardino geothermal system, shaped by fault zones and deep thermal reservoirs. The exceptional heat reflects circulation along major structural breaks in the crust, making this area one of Southern California's most important geothermal zones.
Access is roadside and straightforward, but extreme caution is essential—the water far exceeds safe bathing temperatures. Nearby Dogwood Campground offers excellent base camping within the San Bernardino National Forest. Best visited April through October when mountain roads and nearby hiking trails are fully accessible.
