Hot Springs Valley in Lassen Volcanic National Park sits at 5,816 feet elevation, but surface water reads only 83 degrees Fahrenheit due to mixing with cold mountain runoff. The spring demonstrates classic alpine thermal behavior where heat dissipates rapidly.
Walking through conifer forest at high elevation, you approach a spring that reveals the park's geothermal complexity. Over 200 inches of snow annually shape this landscape, and the thermal features remain modest compared to Lassen's more dramatic geysers and mudpots.
History of Hot Springs Valley
The valley sits within Lassen Volcanic National Park, where hydrothermal features mark zones of residual volcanic heat. The relatively cool water and low mineralization reflect this spring's position in a region of distributed, moderate geothermal activity.
The short walk from Warner Valley Road brings you to this spring. Reservable camping at Warner Valley Campground lies just 2.1 kilometers away. Visit during July through September when snowmelt clears high-elevation trails.
