The highlight of my visit to Lassen National Park. A reasonably easy up and down path of 3 miles and is more than worth the effort. The park notes that this area has all the geothermal features of Yellowstone except geysers. Of course on a much smaller scale but nonetheless very impressive and great photo ops. Nice interpretive signage that... More

Really cool hike with lots to learn about the geological reasons why we have sulfur pits, hot springs, etc around volcanic areas. Smell is not for the faint of heart, but worth checking out.

While very much affected by the drought, it's still well worth the effort of the somewhat grueling 3 mile round trip hike to get to this other worldly site. The boardwalk around the site makes it safe to view the bubbling & boiling lakes & mud pots. Along the way, you can take advantage of amazing views of the mountains,... More

Stopped at Lassen with our teens just to see this area. Hike is not steep until the end. We just took our time. Would wear tennis shoes or hiking boots, apply bug repellent and take water. Thermal activity was amazing to see. Would highly recommend. Also saw deer in the park.

Easy hike to Bumpass Hell. Interesting history, named after the discoverer, Bumpass, after he lost a leg to the boiling pits here. Very colorful. You will see fumaroles, mudpots, aquamarine water contrasting with bright yellow earth. At the end of the boardwalk is a pretty lake. There were some purple wildflowers during June adding more to the color. It's like... More

Along the walk to Bumpass Hell you get great view of many of the peaks in the park. But Bumpass Hell is like nothing you've seen before - boiling mud, steam blowing out of rocks, an overwhelming stench of rotten eggs. Don't miss it.

It's a 3 mile round trip hike starting at 8,234 feet elevation. Has about a 300 foot elevation gain and is a moderate walk. Loved the views and enjoyed the snow patches. The vent pools are interesting and worthy of bring your camera.

The hike is nice. Once you get back into the Bumpass Hell you may feel like you are in another world or made it out to Yellowstone. Sure it's stinky, but it's a cool site and the kids love being able to say hell and not get in trouble. You may pass a prude or two saying heck instead.

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.
