Bumpass Hell is Lassen Volcanic National Park’s largest and best hydrothermal area featuring a colorful basin of fumaroles, boiling mudpots and steaming pools and springs. The basin is reached by a mostly easy 3 mile (4.8k) round trip hike from a large parking area located along the main park road about 6.5 miles (10.5k) from the southwest entrance of the... More

beautiful place once u get used to the smell of sulphur. Nice hike from Lake Helen, but worth the effort. Take lots of water along.

The volcanic activity at the end of the Bumpass Hell is not the best park of this trail, the best part is getting there. You will hike past scenic valleys and large meadows as you make your way to the steam vents and boiling mud pots. Steep hike in and out of where they have all the activity, but the... More

My favorite part of the park was the Bumpess Hell hike, where you get to walk on the boardwalk over some active bubbling thermals. The colors were beautiful. The hike there isn't too bad, it gives a view of the valley. Parking was hard here because I think it is the park's most popular hike. Yes, there the smell of... More

The trail leading to Bumpess Hell is just wonderful! Beautiful vistas of the valley below can be seen, then at the end you reach Bumpess Hell. Just wonderful to explore. It is stinky, there is the smell of sulfur in the whole area. It's kinda like a "mini" Yellowstone! The bubbling pools are really neat and so are the unusual... More

The Bumpess Hell trail is one of the signature trail in the park as it is short, about 3 miles round trip that can easily be done in 1-2 hours with little elevation gain. It was packed with people and you literally were shoulder to shoulder. The sulfur smell is fairly mild compared to Yellow Stone national park but still... More

Bumpass Hell is a thermal area in Lassen Volcanic National Park. There are no geysers there but there are boiling lakes, fumaroles and mud pots. It was named after Kendall Bumpass, a local character and cowboy who lived nearby in the 1860’s - well before it became a park. The story goes that he was showing some guests around the... More

Boiling cauldrons and sulfur colored soil make this steaming vent fascinating. An easy hike with a short section of descent/ascent.

Sometimes called the "poor man's Yellowstone," Lassen Volcanic National Park is not widely visited. We were there Labor Day weekend and found two large campgrounds largely deserted. And while it's true that, despite mountain views, waterfalls, thermal features and wildlife, it is not as extensive in any of those categories as its big brother. Of course, if you are "National...

There is an easy walk to reach the heart of Bumpass Hell, with a little bit of up and down at the end. You can tell you're near the end because of the smell (sulfur compounds) and the noise (bubbling of the pools). What a way to announce an unforgettable experience! The park did a very nice job of building... More
