3 Best Sights in Lassen Volcanic National Park, California

When this plug dome volcano erupted in 1915, it spewed a huge mushroom cloud of debris almost 6 miles into the air. You can admire the peak from a number of points along the park road, and a fabulous panoramic view rewards those who make the strenuous 2½-mile hike to the 10,457-foot summit.

Lassen Peak's 1915 eruptions cleared this area, which makes up a good chunk of the center of the park, of all vegetation, though after all these years the forest has gradually returned. The easy ½-mile interpretive trail loop is wheelchair accessible.
