Lassen Volcanic NP Warner Valley Thermal Features

Sunday November 16, 2025

There's three thermal areas in the Warner Valley section of Lassen Volcanic NP. This area of the park is much quieter than the west side of the park with the visitor center and through road.

Devil's Kitchen is a mix of fumaroles and hot springs that you can see on a loop trail through the area. Boiling Springs Lake has a collection of hot springs on the south side with some bubbling springs and mud pots. Terminal Geyser has a couple of bubbling hot springs and fumaroles creating lots of steam. The actual geyser is behind them and hard to see due to the steam.

These videos were taken with a cell phone camera on photo mode. That's why it's in 4:3 aspect ration. The photos will be in an upcoming photo blog. The hike to see all three was 11.5 miles.
