Where Fire and Ice Meet
Established in 1916, Lassen Volcanic National Park protects 106,452 acres of volcanic wonders. The park showcases all four types of volcanoes (shield, composite, cinder cone, and plug dome) and features the largest plug dome volcano in the world, Lassen Peak.
Known for its active hydrothermal areas, including boiling springs and steaming fumaroles, the park offers visitors a glimpse into the volcanic forces that continue to shape our planet. The landscape ranges from high-altitude volcanic terrain to peaceful mountain meadows and crystal-clear lakes.
