Lassen Volcanic National Park is Open with Limited Winter Access

Enjoy your visit to Lassen Volcanic in the winter season by bringing everything you need. Services and facilities are limited. The 1-7 day winter entrance fee is $10 through April 15.

Getting Around

  • Highway Closed to through Traffic. Vehicle access is limited to the Loomis Plaza (1 mile from the Northwest Entrance) and to the Kohm Yah-mah-nee Visitor Center (1 mile from the Southwest Entrance). The remaining 28 miles of the park highway is closed to through traffic and serves as a snow-covered route for snow sports.
  • The parking lots at Kohm Yah-mah-nee Visitor Center and Manzanita Lake/Loomis Plaza may fill on weekends and holidays. Consider arriving earlier in the day to secure a parking spot.
  • All Trails Are Snow-Covered. View snow depth measurements below. Bring layers, low temperatures drop into the 20s and 30s (°F) in the winter. View weather forecasts. If you want to access a trail inside the park, you must walk on the closed, snow-covered road to reach the trailhead. This will add significant mileage to your hike. During the winter, trails are considered "routes". Skis or snowshoes are necessary.
  • Outlying Park Roads are Closed: The Warner Valley, Butte Lake, and Juniper Lake Roads are closed due to snow.
  • Winter Driving: we recommend carrying chains when visiting the park between October and May; winter conditions can arrive at anytime. Learn more about winter road conditions/access. Check the CalTrans Road Conditions website for chain restrictions.
  • There are no fuel stations open in the park. Please fill up your gas tank before entering the park (see nearby areas with gas stations).


  • Snowshoes and other winter equipment rentals are not available at the park. Come prepared with your own winter equipment. Click here for a list of local businesses that rent winter equipment.
  • Limited food and supplies are available only at the Kohm Yah-mah-nee Visitor Center, Saturday and Sunday, 11 am - 2 pm.
  • Kohm Yah-mah-nee Visitor Center is open Wednesday through Sunday. The exhibit area and auditorium are closed due to COVID-19 precautions.

Things To Do and Know

  • Lake Ice Safety: do not walk on ice-covered lakes or streams. In particular, straying off the trail around Manzanita Lake onto lake ice is dangerous. Ice is unstable and thin especially with warm and sunny daytime conditions. With warm daytime temperatures and low 30s at night in recent days, the snow covering Manzanita and Reflection Lakes is melting - creating pools of water on top of the ice. This creates rapid ice melt. Though ice may look solid, walking on it is taking a big risk! Do not walk onto the ice!
  • Snow camping is only at the relocated Southwest Walk-in or in the backcountry:
    • Building fires on top of the snow or on top of pavement is prohibited. Contained grills, gas stoves, lanterns, and generators are permitted. Do not dump charcoals and ash. Let cool and dispose of in a garbage receptacle or take home for disposal.
    • Backpackers must obtain a free permit to backcountry camp, and must be prepared for traveling and camping in snow.
  • The park does not provide avalanche forecasts. You can link to area forecasts on our Winter Safety page.
  • While covered with snow and ice, the Bumpass Hell trail is treacherous and unsafe in several areas. We do not recommend trying to reach this area in the winter. Access to the trailhead by vehicle and the trail is typically open July through October. Read more about hiking Bumapss Hell Trail in summer and fall.
  • Snowshoeing, skiing, and sledding are options for winter snowplay and exploration in both the Southwest and Manzanita Lake Areas.
    • Travel by foot is the only way to explore the park beyond the entrances.
    • Throughout winter, the ground is covered with deep snow and snowshoes or skis are necessary to go beyond parking areas.
    • Be sure to bring equipment with you, the park does not rent winter equipment. Click here for a list of local businesses that rent winter equipment.

Current Trail Conditions

Southwest Entrance (Kohm Yah-mah-nee Visitor Center)

  • Southwest area winter routes - All routes are snow-covered. Snowshoes or skis are necessary. It is generally possible to hike to Sulphur Works without snowshoes (wearing hiking boots with microspikes). However, during snowfall and days following moderate snowfall, it can be impossible to hike to Sulphur Works without snowshoes or skis. If attempting winter routes, orientation tools such as topo map, GPS, or compass are advised for route-finding.
  • Sledding - there is enough snow coverage on the snow play area. Use caution when sledding. Be aware of hard-packed and icy snow, obstacles under snow and drainages.
  • Avalanche conditions may be elevated. The park does not provide avalanche forecasts. Learn about avalanche precautions on our Winter Safety webpage. We advise caution in avalanche terrain, as fresh powder is sitting on top of hard-packed, icy snow.

Northwest Entrance (Manzanita Lake/Loomis Plaza)

  • Northwest area winter routes - All routes are snow-covered. Snowshoes or skis are necessary. It is generally possible to hike around Manzanita Lake without snowshoes (wearing hiking boots with microspikes). However, during snowfall and days following moderate snowfall, it can be impossible to hike without snowshoes or skis.
  • Walking the trail around Manzanita Lake is a popular activity in winter. Walking off the trail and onto the ice-covered water is not advised. Ice may not be thick enough to support the weight of a human. Plunging into ice cold water on a cold winter day is risking hypothermia.

Winter Snow Season Routes - General Information

  • Trails are usually snow-covered during the winter snow season, approximately November through April.
  • You must hike/snowshoe/ski on the closed, snow-covered park road to reach snow-covered trailheads in the interior of the park. This will add significant mileage for your hike.
  • View winter routes in the Winter Guide for over-the-snow travel with snowshoes or skis.
  • Trails at higher elevation including Lassen Peak and Bumpass are often snow-covered into June or July.
  • Trails at lower elevation (Manzanita Lake, Butte Lake, and Warner Valley Areas) are the first to become snow-free.

View a list of day hiking trails for condition updates for specific trails. Most hiking trails are snow-covered and not accessible during winter and early spring. During the winter, hiking trails become winter routes. Find out what it's like to hike at Lassen Volcanic National Park if you're Visiting in Spring or Visiting in Winter.
