Current Conditions & Information

Lassen Volcanic National Park is Open.

Please review current closures, restrictions, and seasonal information:

  • Smoke from nearby wildfires is visible in the park and conditions vary from day to day. Learn more about air quality in the park.
  • A fire restriction is in effect. All campfires and open flames are prohibited park-wide due to severe fire danger. Gas stoves, lanterns, and generators are permitted.
  • Warner Valley, Juniper Lake, and Butte Lake Campgrounds are closed for the 2020 summer/fall season due to severe wildfire danger. Learn more.
  • Demand for campsites is likely to be higher than normal due to a temporary closure of dispersed camping (camping outside of developed campgrounds) on all National Forests in California on 9/21, including Lassen National Forest, which surrounds the park. Reservations are highly recommended; learn more about camping.
  • Popular trailhead parking areas can fill up by mid-morning. This includes Bumpass Hell, Kings Creek Falls, and Hat Creek. Plan to arrive early and have one or more alternative trails if parking is unavailable. Trailheads with limited parking are identified with a [P] on the trail conditions page.
  • Bumpass Hell Trail is open and busy. Consider an alternative such as Sulphur Works or one of the numerous hikes to hydrothermal areas in the Warner Valley Area. If you still plan to hike the trail, please wear a face covering when passing others and in other situations where a 6-foot distance cannot be maintained.
  • A closure on Manzanita Lake prohibits swimming, wading, and the use of soft-sided flotation devices. Hard-sided boats may be used on the lake except in an area along the western shore that is closed to all use.
  • A backcountry camping closure is in place on the east side of the park due to a bear obtaining food from campers. Backpackers must obtain a free permit and store all scented items and food in a NPS-approved, bear-resistant container.
