Tucked away in far northeastern California, Lassen offers sweeping grandeur and hydrothermal marvels in an uncrowded, contemplative atmosphere. The park is home to more than 40 volcanoes, bubbling mudpots, steaming fumaroles, stunning mountain views and vast, naturally dark skies. The park's namesake peak is the one of the largest plug dome volcanoes in the world — a type of volcano that grows in size from layers of its own lava building on top of each other over time.
