Lassen Volcanic National Park

Park Overview

Lassen Volcanic National Park preserves one of the most recently active volcanic landscapes in the continental United States, where steaming fumaroles, bubbling mudpots, and crystal-clear mountain lakes tell the ongoing story of Earth's volcanic power. Following its dramatic 1915 eruption, Lassen Peak remains a centerpiece of this geothermal wonderland that showcases all four types of volcanoes found on Earth.

The park's 106,372 acres encompass a remarkable diversity of volcanic features and ecosystems, from hydrothermal areas rivaling Yellowstone to pristine wilderness lakes and ancient forests. Sitting at the southern end of the Cascade Range where it meets the Sierra Nevada and Great Basin, Lassen offers a unique convergence of geological forces and biological diversity, all accessible via scenic drives and over 150 miles of trails.
