Nestled in Northern California’s wilderness, Lassen Volcanic National Park is one of America’s most underrated natural gems. Known for its steaming fumaroles, crystal-clear lakes, and dramatic volcanic landscapes, the park offers a fascinating mix of geothermal wonders and alpine beauty — all without the crowds of Yosemite or Yellowstone. Whether you’re a hiker, photographer, or nature lover, Lassen has something unforgettable to offer.
1. Explore Bumpass Hell
If there’s one place you can’t miss in Lassen, it’s Bumpass Hell, the park’s largest hydrothermal area. This otherworldly landscape features boiling springs, bubbling mud pots, and steaming fumaroles that showcase the raw power of the Earth beneath your feet.

- Elevation Gain: 2,000 feet
- Reward: Panoramic views of Mount Shasta, the Sierra Nevada, and the volcanic landscape below.

4. Visit the Sulphur Works
Just a short walk from the main park road, Sulphur Works gives visitors an up-close look at boiling mud pots and steaming vents. It’s the most accessible geothermal area in Lassen and is especially impressive in the early morning when steam drifts across the boardwalk.
5. Hike the Devastated Area Interpretive Trail

A lush, shaded trail leads you through meadows and forests to the spectacular 40-foot Kings Creek Falls. The cascading water and surrounding greenery make this one of Lassen’s most photogenic spots.

Designated as an International Dark Sky Park, Lassen offers some of the clearest night skies in California. On moonless nights, the Milky Way arcs vividly across the sky — a dream for photographers and astronomy lovers.
- Best Spots: Manzanita Lake, Summit Lake, or Kohm Yah-mah-nee Visitor Center.
8. Explore the Subway Cave Lava Tube
Just outside the park’s northern entrance, the Subway Cave invites visitors to walk through a mile-long lava tube formed 20,000 years ago. Bring a flashlight and a jacket — it stays cool and pitch-dark inside!
