The Lassen Volcanic National Park is one of the national parks in Northern California. The main attraction is the Lassen Peak, one of the world’s largest plug dome volcanoes. Lassen Peak is considered an active volcano that’s surrounded by boiling mud pots, fumaroles, and hot springs. Although there are no glaciers in this national park, there are 14 permanent snowfields due to glacial scarring.

All types of volcanoes can be found in this national park: plug dome (Lassen Peak), composite (Brokeoff Volcano), shield (Prospect Peak), and cinder cone (Cinder Cone). The United States Geological Survey constantly monitors volcanic activity in the area. The mineral-rich volcanic soil contributes to the lush vegetation in the park.


When To Go

There are attractions all year round. Summer (July to September) attracts the most visitors. Those who visit during summer have full access to activities and services. Spring (April to June) and Fall (October to November) attract fewer visitors. Some services and activities are closed due to the changing weather and the lower rate of admissions.

During winter (December to March) attract the lowest number of visitors. Fortunately, fun winter activities such as skiing and snowboarding replace summer activities.
