Lassen Volcanic National Park Map

ONE OF THE LEAST DISCOVERED PARKS in the western United States, Lassen Volcanic National Park is a real-world laboratory that shows how landscapes evolve over time following a major volcanic eruption. Boiling springs, mudflows, lava fields, and cinder cones reflect the park’s violent geologic legacy. But Lassen is much more than basalt and ash. The park also harbors numerous lakes and meadows, thickly forested areas, and a rich catalog of wildlife.

The origins of this volcanic landscape stretch back more than three million years, when powerful mudflows, or lahars, rushed down the flanks of Mount Yana, covering a 2,000-square-mile area—including what is now Lassen Volcanic National Park. There has been volcanic and hydrothermal activity ever since, culminating in a massive stratovolcano called Brokeoff Mountain (Mount Tehama), which dominated the landscape between 600,000 and 400,000 years ago.

When American explorers and pioneers first reached the area in the early 19th century, they most likely assumed the volcanoes were dormant. So it would have come as a huge surprise when Lassen Peak rumbled to life in 1914, a three-year episode that included a massive eruption in May 1915 that spewed ash, rock, and lava over much of the park’s northwest quadrant.

Even before that last eruption, Lassen was deemed a geological wonder. In 1907, President Theodore Roosevelt designated both Cinder Cone and Lassen Peak as national monuments. A year after the 1915 eruption, they were combined into Lassen Volcanic National Park, one of several units of the nascent national park system.

The park is unique on several levels. It is one of the few places on Earth where visitors can view all four volcano types—plug dome, cinder cone, shield, and composite—within a relatively small area. Lassen Peak is the southernmost active volcano in the Cascade Range. Lassen and Mount St. Helens were the only volcanoes to erupt in the Lower 48 states during the 20th century.

All told, more than 75 percent of the park is designated Wilderness— easily accessed, even via day hikes.

How to Visit

Nearly everyone who visits the park drives the 30-mile stretch of Lassen Volcanic National Park Highway that meanders past volcanic peaks and through hydrothermal areas between the Kohm Yah-mahnee Visitor Center and Manzanita Lake. While the scenic drive reaches many of the tectonic highlights, it offers only a hint of Lassen’s pristine backcountry. Less-traveled unpaved roads take visitors to such secluded spots as Cinder Cone and Butte Lake in the park’s northeast corner and the hydrothermal splendor of Warner Valley in the south, as well as quiet Juniper Lake in the southeast.

Useful Information

How to get there

From Sacramento (about 180 miles south), take I-5 north to Exit 649 in Red Bluff, then Calif. 36 east to Calif. 89 north. The park’s southwest entrance and visitor center are about 5 miles from the 36/89 junction. Other routes include Calif. 44 from Redding to the Manzanita Lake Entrance Station, and a combination of U.S. 99, Calif. 70, and Calif. 89 from Sacramento to the southwest entrance.

When to go

The park is open year-round, but many park facilities are closed generally between mid-Oct. and late May. The main park highway is closed during the winter season, and the Kohm Yah-mahnee Visitor Center may close at any time due to weather.

Visitor Centers

Kohm Yah-mah-nee Visitor Center, about 5 miles north of the turnoff from Calif. 36, is closed Mon. and Tues. early Dec. through March.


P.O. Box 100 38050 State Highway 36E Mineral, CA 96063 530-595-6100


Seven developed campgrounds (430 sites) take reservations (; 877-444-6777). Backcountry camping requires a free permit (530-595-4480 for information, or visit the Kohm Yah-mah-nee Visitor Center).


Lodging is limited to two park locations open June to mid-Oct. The historic Drakesbad Guest Ranch is 17 miles north of Chester, CA, in Warner Valley, and the Manzanita Lake Camping Cabins is in the park’s northwest corner; for information on both: lassenlodging .com; 530-779-0307 (summer), 877-622- 0221 (winter).
