Basic Facts About Lassen Volcanic National Park

Located in Northern California, Lassen Volcanic National Park is home to the iconic Lassen Peak as well as a variety of geothermal and hydrothermal features. These features include volcanoes, steam vents, geysers, mud pots, painted dunes, and more. A lesser-known U.S. national park, Lassen Volcanic National Park offers visitors an excellent opportunity to get off the beaten track.


Lassen Volcanic National Park began as two distinct national monuments, Cinder Cone National Monument and Lassen Peak National Monument, which were established by President Theodore Roosevelt in 1907. The park garnered national attention in 1914 and 1915 with volcanic eruptions from Lassen Peak, and became officially recognized as a national park in 1916.

The region had been inhabited by Native Americans since ancient times, but was then settled by European immigrants who used Lassen Peak as a landmark on their way to the Sacramento Valley. Danish immigrant Peter Lassen settled in the area and became a guide for those on their way to the valley, and the park was eventually named after him.


Lassen Volcanic National Park is characterized by volcanoes and volcanic features that resulted from hundreds of thousands of years of violent eruptions. These geothermal and hydrothermal components include steam vents, mud pots, geysers, volcanic peaks, painted dunes, lava flows, boiling pools, sulfur vents, valleys, craters, and canyons. The area is forested, and there are also a number of lakes, streams, and vast meadows throughout the park.
