Join Lassen Volcanic staff and scientists from the U.S. Geological Survey for special events celebrating a series of Lassen Peak eruptions that brought Lassen to the world stage and helped pave the way for the establishment of the park on August 9, 1916. “We have a weekend full of activities planned, from a commemoration celebration to campfire talks,” stated Superintendent Steve Gibbons. “We are excited to share stories of Lassen’s eruptive past with our visitors over the Memorial Day weekend.”

Many of the park trails are still snow-covered, including Lassen Peak and Brokeoff Mountain trails. The Lassen Peak Trail is only open for over-snow travel and mountaineering equipment is strongly recommended. An ice axe, crampons or skis are necessary to safely travel on Lassen Peak. The Bumpass Hell trail remains closed due to snow.Higher elevation, snow-covered trails tend to be icy in the mornings and slushy and slippery by afternoon. Hiking in these areas require sturdy hiking boots and trekking poles. For visitors wishing to avoid snowy areas, trails in the Manzanita Lake, Warner Valley and Butte Lake areas are snow-free. 

After a brief closure due to a late season snow storm, the Lassen Volcanic National Park Highway is open once again for through traffic. Warner Valley Road and Butte Lake Road are also open for the season. Juniper Lake Road is anticipated to open in late May.

Even though it feels like summer in the valley, visitors should still be prepared for cool conditions as mountain weather can change quickly. It is best to dress in layers and bring food, water, sunscreen and sunglasses.
