Lassen Volcanic National Park in California, USA - map, photos and visitor information

Lassen Volcanic National Park in northern California brings volcanic peaks, steaming ground, lakes, and forest into one mountain landscape. The main highway links its northwest and southwest entrances when snow allows. Choose your entrance and check the road before planning a through-drive; the eastern districts need separate approaches.

Highlights along the park highway

• Bumpass Hell: Walk toward a hydrothermal basin and follow its boardwalks when the seasonal route is open.
• Manzanita Lake: Explore a lower-elevation lakeshore near the northwest entrance.
• Lassen Peak: A demanding mountain hike offers a different experience from the roadside stops.
• Devastated Area: A short interpretive walk introduces the volcanic landscape without a summit climb.

Plan around snow and separate districts

Fees, hours, and seasonal access

The official conditions hub connects road, trail, fire, and weather information. An open visitor center does not establish that the highway is open from end to end.

Keep clear of hot ground and burned trees

Stay on established trails and boardwalks in hydrothermal areas. A surface that looks firm can conceal boiling water or mud. Do not touch thermal water or apply mud to your skin. These are viewing areas rather than soaking pools.

Burned areas can contain unstable trees, concealed holes, loose rock, and difficult crossings. Snow and high elevation add hazards on mountain routes. Carry water, suitable footwear, layers, and navigation information. Cell coverage is limited. NPS prohibits bear spray in this park; read its safety guidance before choosing equipment.

Protect recovering ground and wildlife

Leave plants, stones, and cultural objects where they are. Do not feed wildlife or leave scented supplies unattended. Pets cannot use park trails, including snow-covered routes or travel in a carrier. Plan pet care around the developed areas where they are permitted.

Follow fire restrictions and use campground fire rings only where fires are allowed. Backcountry campfires are prohibited. Avoid shortcuts that damage vegetation or loosen rocks above other hikers.

Entry, campsites, and wilderness permits

Ordinary park entry does not require a reservation. Most campgrounds do. Arrange them before reaching areas with unreliable reception. The campground guide lists facilities and booking channels. Confirm Warner Valley arrangements with its operator.

Overnight backcountry camping requires an online wilderness permit through Recreation.gov. Booking opens up to 90 days ahead. The fee is USD 6 per permit plus USD 5 per trip for each person age 16 or older. Approved bear-resistant containers are required April 16–November 30; hanging food is not an alternative. Follow the wilderness permit instructions for storage and campsite restrictions.

Maps and the two highway entrances

Use State Route 44/89 for the northwest entrance near Shingletown and State Route 36/89 for the southwest entrance near Mineral. Kohm Yah-mah-nee Visitor Center is at 21820 Lassen National Park Highway, Mineral, CA 96063. Butte Lake, Juniper Lake, and Warner Valley have separate eastern access roads that are not maintained for winter travel.

There is no public transport to or within the park. Plan your own transport and return route. The official maps include general orientation and links to detailed topographic coverage. Do not use a central park pin as the destination for every district.

Nearby parks on regional routes

• McArthur-Burney Falls Memorial State Park: Continue toward Burney on Highway 89; its entrance is north of Highway 299.
• Ahjumawi Lava Springs State Park: Drive through McArthur from Highway 299 to the Rat Farm boat launch. Reaching the park itself requires a boat.

Choose a lakeshore walk or a mountain hike

• Manzanita Lake: The 1.8-mile route offers a shorter lakeside outing.
• Devastated Area: A 0.3-mile interpretive walk suits a stop between longer activities.
• Lassen Peak: The five-mile round trip is strenuous. Snowfields and exposed terrain can make it unsuitable even when the trailhead is reachable.

Bumpass Hell involves an approach hike followed by a descent into the basin. Parking can fill during the middle of the day. Check the route before starting and carry water; toilets are at the trailhead rather than along the basin walk.

Visitor centers, camping, and access needs

The southwest visitor center has exhibits, a bookstore, and seasonal commercial services. Loomis Museum provides information near the northwest entrance. Both have accessible entrances, with designated parking and nearby accessible restrooms. Ask about the specific route you want to use rather than assuming every volcanic trail has the same surface.

Campgrounds provide tables, fire rings, and food lockers. Drinking water and flush toilets can be shut off for autumn dry camping. No park campground has RV hookups. Manzanita Lake has a camper store, paid showers, laundry, and a dump station during its service season.

Accessible campsites are identified at Manzanita Lake, Summit Lake North, and Butte Lake. Manzanita camping cabins and Drakesbad lodging are listed through the park concessioner; confirm operation and availability before planning a stay.

About Lassen Volcanic

People within the volcanic landscape

The Lassen region served as a meeting place and seasonal homeland for Atsugewi, Yana, Yahi, and Maidu people. Later emigrant routes crossed the area. Photographer B. F. Loomis helped document eruptions and contributed to visitor facilities near Manzanita Lake. These histories add context to the landforms along the highway.

Habitats from lakes to high slopes

Forests, meadows, water, and higher volcanic terrain support different groups of birds, mammals, reptiles, and amphibians. Black bears use the park, so food storage matters at both camps and picnic stops. Watch animals from a distance and allow them to continue feeding or moving without interference.
