Things To Know Before You Come
Lassen Volcanic NP is a remote mountain park full of solitude and abundant recreational activities. Weather plays a dramatic role at Lassen Volcanic National Park. Winter, especially, shapes the landscape; snow generally begins to accumulate each year in October, doesn't melt in most places until July, and can remain in isolated areas year round. Summer weather is more predictable, with warm, dry days, blue skies, and cool nights. Visitors to Lassen Volcanic National Park should be prepared for any kind of weather, any time of the year. Careful planning and awareness of park conditions will ensure an enjoyable visit.
Use the "Things to know before you come" section of the website to familiarize yourself with the roads within and around the park, weather and safety concerns, pet regulations, and lodging, dining, and shopping options within and outside of the park.
