December Through MarchWinter is a season of snow and solitude. Vehicle access is limited, but over-the-snow adventure is seemingly endless. Access is LimitedLassen’s main park road (Hwy 89 through the park) closes when snow settles in and vehicle access is limited to Kohm Yah-mah-nee Visitor Center (southwest entrance) and Loomis Plaza/Manzanita Lake parking area (northwest entrance). The road typically closes for the season in mid- to late November. Roads to outlying park areas (Butte Lake, Juniper Lake, and Warner Valley) may close with winter conditions as well. Typically, these roads are not maintained in winter and may be gated for safety. Road closures are listed in park alerts, which appear at the top of each page and on the Alerts & Conditions page. WeatherBe prepared for rapidly-changing, severe weather conditions. Wear layers, waterproof gear and outerwear, and sun protection.The park receives up to 30 feet of snowfall during the snowy season (typically November to May). Sunny skies are common between short (1 to 3 day) snowstorms. The park’s snowpack often lasts more than half of the year. Winter/spring temperatures in the Southwest Area (6,700 feet elevation) range from highs of 50°F to 61°F to lows of 13°F to 23°F. Temperatures in the Manzanita Lake Area (5,800 feet elevation) run about 5° warmer. Expect a 5° temperature decrease for every 1,000-foot increase in elevation.
