Devils Kitchen is Lassen’s second largest hydrothermal area and features fumaroles, hot springs, and mudpots. Devils Kitchen is located about 5 miles southeast of Lassen Peak at the upper end of Warner Valley on Hot Springs Creek. The hot springs in this area are so acidic that they have eaten pits and holes in the bedrock. From the Warner Valley Trailhead it is a 4.2 mile round trip to Devils Kitchen. A 1983 USGS inventory of the thermal area included nearly 150 hot springs and fumaroles. (

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.
