Lassen Volcanic Information

Nestled in the peaceful forests and wilderness of Northern California is Lassen Volcanic National Park, home to hissing fumaroles and boiling mud pots.

Known for its remarkable hydrothermal features, Lassen Volcanic National Park offers visitors a glimpse of plopping mud pots, bubbling pools, and roaring steam vents.  

“All Nature's wildness tells the same story: the shocks and outbursts of earthquakes, volcanoes, geysers, roaring, thundering waves and floods, the silent uprush of sap in plants, storms of every sort, each and all, are the orderly, beauty-making love-beats of Nature's heart.” — John Muir

Park Information

Nestled in the peaceful forests and wilderness of Northern California is Lassen Volcanic National Park. Lassen Peak is the largest plug dome volcano in the world and the southernmost volcano in the Cascade Range. 

Established in 1916, Lassen Volcanic National Park is home to meadows freckled with wildflowers, clear mountain lakes and numerous volcanoes. A closer look at the landscape, however, reveals the hissing fumaroles and boiling mud pots that still shape and change the land, evidence of Lassen's fiery volcanic past.
