Vehicle access in the park is limited to the Southwest and Manzanita Lake Areas in the snowy winter and spring seasons (usually December through April). Conditions can be very hazardous, especially when temperatures drop during the evening and early morning hours.
Play It Safe
Visiting Lassen Volcanic National Park in the winter/spring snow season involves risk. You can reduce your risk by being prepared in the following ways:
Visitors who plan to travel beyond winter routes should be avalanche aware, carry avalanche gear, and know how to use it. Lassen does not provide an avalanche forecast for the park. Forecasts for neighboring areas are available from Mt. Shasta Avalanche Center and Sierra Avalanche Center (Lake Tahoe area). You can also check national avalanche conditions at Avalanche.org.

Be Prepared For Winter Conditions
Your safety is your responsibly. Be prepared for winter conditions, at high elevation, in a remote area. A few suggestions to reduce your risk:
Recreating in a Remote Area
The Manzanita Lake Area (5,800 elevation) consists of gentle slopes and scenic lakes, and offers the easiest routes for snowshoeing and cross-country skiing in the park. The Southwest Area offers steep slopes and sweeping vistas with increased danger of avalanches. This offers the best backcountry skiing and snowboarding terrain for those who practice avalanche awareness.
