Lassen Volcanic National Park Closes Main Road Amid Heavy Snow and Ice

As of November 13th, 2025, Lassen Volcanic National Park has announced the closure of its main through-road due to heavy snow and ice from recent autumn storms in the Shasta Cascade mountains. The Lassen Volcanic Highway, which winds through the park, is now closed to through traffic until early spring.

Despite the road closure, the park remains open for visitors to enjoy a variety of winter activities. Guests can still access the park from the northwest entrance to Loomis Plaza and the southwest entrance to the Kohm Yah-mah-nee Visitor Center. From there, they can ski, snowshoe, sled, camp, and even have the occasional snowball fight during the holidays and throughout the winter season.

However, the majority of the park's other roads, including those leading to Juniper Lake, Warner Valley, and Butte Lake, are closed to vehicles until spring. Park staff advise visitors to check the weather forecast and be prepared for winter conditions before venturing out. They also recommend telling someone where and when they plan to visit the park and checking in upon their return.
