Devils Kitchen

Devils Kitchen is a hydrothermal basin in the park’s outlying Warner Valley, reached by a moderate 4.2-mile round-trip hike. It’s Lassen’s second-largest hydrothermal area after Bumpass Hell, with boiling springs, hot streams, mudpots and steam vents around a short loop. Save it for a day when you want the geothermal features and a proper walk to reach them. The route takes about two hours and has roughly 440 feet of elevation change.

Start at Warner Valley Trailhead. The route crosses meadow on small bridges and boardwalks, passes the Dream Lake Basin junction, then follows Hot Springs Creek, climbs through forest and woodland, and crosses seasonal streams before dropping toward the basin. Reaching the trailhead means driving northwest from Chester on Feather River and Warner Valley roads; parts of the access are gravel, and trailers aren’t recommended. Parking is available at the trailhead.

A bridge leads into a compact field of cracked yellow and red mounds. Look for boiling pools, mudpots and fumaroles, where steam escapes through openings in the ground. The small features make the basin fun to explore slowly: the heat is obvious, but each pool and vent has its own shape and sound.

Rain and snow falling on the highlands filter underground and are heated by hot rock beneath Lassen Peak. The water boils back up in pools and mudpots; superheated steam rises through fractures as fumaroles. These features are signs that the Lassen Volcanic Center is still volcanically active.

The thin ground around thermal features can cover acidic boiling water or mud. Stay on the marked path and boardwalk, and don’t touch or enter the water; the crust can give way and cause severe burns.

For a wide photo, put Hot Springs Creek in the foreground and the pale, steaming slopes behind it. Then look for close details in the yellow mineral deposits and mudpots; they show the colors and textures that disappear in a broad view.
