Lassen Volcanic National Park is home to steaming fumaroles, meadows freckled with wildflowers, clear mountain lakes, and numerous volcanoes. Jagged peaks tell the story of its eruptive past while hot water continues to shape the land.

With over 30 feet of snowfall annually, Lassen provides numerous opportunities for winter recreation.
