Overview
Welcome to Lassen, California’s fiery alter ego. This place isn’t just a park ... it’s a full-blown volcanic variety show. You’ve got steaming fumaroles that hiss like tea kettles, bubbling mud pots that look like Mother Nature forgot to clean her crockpot, and mountains shaped like the earth sneezed and then froze mid-blast. Standing here, you don’t just see geology, you feel it ... you smell the sulfur, hear the burps, and half expect the ground to wink at you and say, “Yeah, I’m still alive.” But Lassen’s not all smoke and brimstone. Step a little farther and suddenly you’re knee-deep in alpine meadows bursting with wildflowers, kayaking across a mirror-still lake, or trudging up a trail that smells like pine-scented adventure candles. It’s that perfect cocktail of serenity and chaos, the kind of place where one moment you’re marveling at nature’s calm reflections and the next you’re side-eyeing a steaming vent thinking, “Please don’t explode while I’m taking this selfie.”

Unique Stories & Facts (Volcanoes, Ghosts & Bad Luck)
- Lassen Peak erupted between 1914–1917, making it the last volcano in the continental U.S. to blow before Mount St. Helens in 1980.
- Bumpass Hell is named after Kendall Bumpass, who discovered the area, fell through the crust, and badly burned his leg. Some say his ghost still limps around the area, warning hikers to watch their step.
- The park has all four types of volcanoes ... shield, composite, cinder cone, and plug dome ... making it a one-stop volcano shop.
- Old ranger tales mention ghostly figures near Sulphur Works, which are probably just steam but make for a good story.
