Boiling Spring Lake is reportedly the third largest body of hot water found anywhere in the world. Hot springs emerge in many locations in the lake, especially along the southern end of the lake. Boiling Springs Lake is located about 7 miles southeast of Lassen Peak in Warner Valley. From the Warner Valley Trailhead it is a 2 mile round trip to Boiling Springs Lake.
The highest temperature of water generally is close to the boiling temperature at the altitude of the particular spring or fumarole The intensity of Lassen’s hydrothermal features varies both seasonally and from year to year. In spring, when cool ground water from snowmelt is abundant, the fumaroles and pools have lower temperatures, and the mud in mudpots is more fluid. In late summer and in drought years, the features become drier and hotter because there is less mixing with shallow, cool ground water.
