Lassen Volcanic National Park, California

With names like Bumpass Hell, Boiling Springs Lake, and the Devastated Area, it’s easy to see why Lassen doesn’t get many visitors per year. Don’t let the names scare you. The park is a fascinating look into the region’s volcanic past. It’s one of the few places in the world where you can see all four types of volcanoes (cinder cone, composite, shield, and plug dome).
There are 150 miles of trails to explore. Don’t miss the three-mile round hike through Bumpass Hell—a cauldron of mud pots, boiling pools, and steam vents. The area was named after Kendall Bumpass, whose leg had to be amputated after he fell into a boiling mud pot. Be sure to stay on the trail for this one.

For those looking for more of a challenge, try the strenuous five-mile Lassen Peak Trail. The climb to the top is rewarded with commanding views of the entire area. Night owls can also hike the trail during a full moon to see the park in an entirely different light (sorry).

Get out of the summer heat with a jaunt through the Subway Cave. This lava tube is ⅓ of a mile long and pitch black, so be sure to bring a light.

Nearby Manzanita Lake just begs to be fished or paddled. Hike around the lake to catch a glimpse of Mount Lassen reflecting in the calm waters.

Even though the park is open 365 days a year, we recommend visiting in summer or fall. Once the snow starts, it can be hard to get around (unless you remembered snowshoes).
