Hot Springs (Surprise Valley)
Hot Springs in Surprise Valley produces water at 208 degrees Fahrenheit, creating a temperature differential of nearly 158 degrees above ambient—one of California's hottest springs. Located at 4,511 feet elevation just 84 feet from the road.
The spring emerges in remote Modoc County terrain characterized by high desert landscape. At this elevation, winters bring significant snow (49 inches annually) and summers are short, creating a stark seasonality that shapes the visitor experience.
Surprise Valley sits in basin-and-range topography typical of northeastern California's volcanic plateau region. The extreme temperatures reflect deep geothermal circulation through fault zones that characterize this volcanically active area.
Access is straightforward from the road, making this remote spring surprisingly accessible. Expect cold winters and brief summers; spring and fall offer the most reliable visiting conditions. The nearby Pepperdine Equestrian Campground provides base camp options.
