Lassen Volcanic National Park is under normal operations with the addition of a few COVID-19 modifications:
Campgrounds and popular trailheads are exceptionally busy this summer.
Roads in the Park
Lassen Volcanic National Park Highway and other park roads are closed for the winter snow season, typically November through May. Road snow clearing operations begin at the Manzanita Lake Area in late March.
Roads to the Park
State Route (SR) 44/89 provides access to the Northwest Entrance/Manzanita Lake Area
New! Road construction at junction of SR 36 & 89 (access to the Southwest Entrance)
Be prepared for delays in both directions on SR 36 due to construction. The traffic control begins at the junction of SR 89 and 36. You may have to wait for traffic control to turn left onto SR89 due to the location of the traffic control stop.
