Posted May 17, 2021

Mineral, CA – Lassen Volcanic National Park Highway will open to through traffic on Monday, May 17. Butte Lake and is currently open. Spring road clearing progressed quickly this year as a result of lower-than-average snowpack and limited spring snowstorms. Visitors should always check conditions before traveling to the park, as the park highway may close unexpectedly, especially during the spring shoulder season.

“The opening of the park highway marks the start of what is likely to be a busy summer and fall season,” said Superintendent Jim Richardson. “Visitors are continuing to discover that Lassen Volcanic National Park provides outstanding opportunities for close-to-home outdoor recreation and relaxation.”

Lassen Volcanic saw a record high 542,000 visitors in 2020, despite a two-month service-wide closure in response to COVID-19. Visitors can make this year’s visit more enjoyable by being prepared for busy parking areas, hiking trails, and campgrounds. Parking areas and trailheads are generally less busy in the morning and late afternoons and on weekdays. Campsite reservations are highly recommended, and most campsites are now reservable.

Manzanita Lake Campground, cabins and Camper Store open May 21. A handful of walk-in campsites at the year-round Southwest Campground are snow-free. Additional campground opening dates include 6/4 - Butte Lake and Warner Valley; 6/11 - Lost Creek Group; and 6/25 - Summit Lake and Juniper Lake. Learn more about camping in the park at

The Kohm Yah-mah-nee Visitor Center is open daily, 9 am to 5 pm. Masks are currently required inside the visitor center and all park facilities; the NPS is working to determine how the new CDC mask guidance will be applied in parks. Park auditoriums are currently closed; however, the park film is available on the park website. Loomis Museum will be open Friday through Sunday, 5/22 through 6/21 and then daily beginning 6/22.
