Traffic & Travel Tips

Access to Lassen Volcanic National Park depends heavily on the weather. Following the winter season, the 30-mile park highway may open to through traffic as early as early as the of May or as late as mid-July. Visit the conditions page for current road status. Beginning in April, road clearing progress can be followed on the spring road clearing page.

 

Directions for Travel Around the Park

It is possible to travel around the park around both the east and west sides of the park when the highway is not open to through traffic to access the northwest or southwest entrances.
Lassen Volcanic National Park Highway is closed to through traffic for the winter season, usually November through May. Sections of the highway may also close temporarily in the spring and fall following snowfall or freezing temperatures. View or download Directions for Travel around the Park (PDF, 96 KB).
 

Winter Driving

Please remember that high-elevation roads are often icy or snow-covered during the fall and winter and can be very hazardous, especially when temperatures drop during the evening and early morning hours. Carry tire chains in your vehicle from October through May. Chain requirements can be instituted at any time; even four-wheel drive vehicles with snow tires can be required to chain up. Watch for highway advisories posted in Red Bluff and Redding. CalTrans will post chain requirements on Highways 36 and 44.

To check for chain requirements, road closures, or other highway advisories before your trip, call the CalTrans Highway Information Network at 1-800-427-7623 or go to the CalTrans website at: http://www.dot.ca.gov/hq/roadinfo.
