Bubbling mud pots, sulfur vents and boiling pools make this trip to hell and back well worth the effort. Located four hours north east of San Francisco this Northern California park might be a little out of the way, but it's a prime destination for seekers of tranquility and those with even just a passing interest in geology. Sticking to the trail is always recommended, but if you're visiting Bumpass Hell it is a must follow rule. To illustrate the point you have to look no further than the man who discovered these volcanic hotsprings, Kendal Bumpass, who managed to fall in and injure his leg not once but twice, the second time requiring his leg to be amputated! Scare-stories aside, this really is an easy family friendly hike with little in the way of danger as long as you keep the little ones under control.

Did this in 2016. Had to take an alternative route as the main trail was closed for renovations

A well-marked trail that offers beautiful views, varied terrain and a good opportunity to see the geothermal vents.

My husband and I hiked Bumpass Hell in August with our boys ages 10 and 13. It was a great out and back hike with views along the way and a great reward of the cool Bumpass Hell area. Bring water. There are bathrooms at the trail parking lot. We added the hike to Cold Boiling Lake which starts at the Bumpass Hell area.

Very windy and very chilly! Start this hike early! We were fighting with daylight on the way back- but it was unlike anything we'd seen before. Cool views! It's harder to breathe at this elevation.

A unique trail and a great taste of what Lassen Volcanic has to offer! Great views the whole way through. Be careful on the edges! ;-)

I did this in the snow in July and it was so slippery even with micro spikes! I'd recommend also having hiking poles if you go in the snow. Super easy and rewarding otherwise. Highly recommended.

My husband & I did this last Sat and it was beautiful. The weather was nice with a crisp cool air and the sun was shining. It was our first time in Lassen Park and we were very pleased with the surrounding beauty. Seeing the sulfur pools was amazing, we did this adventure in one day and then had a 3 hour drive home. We will definitely be coming back as we want to see the subway caves & painted dunes.

The first part of this trail is really easy to do for everyone. The second part it's even easier to do because it is a downward path that takes you to the pools of sulfur and the walkways that keep you safe from the unstable ground in some areas. There are some photo ops and those may vary from day to day, not always you get the spectacular bubbling that you expect. The return hike may be difficult to do as the first part is steep but it's a good hike nonetheless.

Absolutely gorgeous trail fairly straightforward and well marked. We went on to cold boiling lake trail despite thunder and lightning and we're especially thankful for the excellent trail markings when we returned to the entrance as over an inch of snow had accumulated. Spectacular views. We communed with two deer families along the way.

Harder than easy, easier than moderate. A great introductory trail to get to know Lassen. Roof of California. Loved it.

Very easy hike, would say it's more of a tourist attraction but cool nonetheless.

Great hike! Full of science and history!

Arrive early to beat the crowds and have all the amazing fumaroles to yourself! A short hike that is definitely worth it.

Great hike...good views along the way and cool Yellowstone like mud pots with sulfur and steaming volcanic areas. Only open a short time because snow and safety concerns. Lots of snow when we went on July 9.

Easy and popular trail. Uphill climb for a short section on the way back. Fascinating geothermal features. Parking lot is small and looks to fill up very fast.

Absolutely loved this trail. It is great for all ages. The incline is gradual and hardly noticeable heading towards Bumpass Hell. Heading out the incline is not so easy, however, doable, and it doesn't last long. The scenery and views are gorgeous. Bumpass Hell is like being on another planet. So amazing. You can feel the heat from the mud pots as soon as you enter. A must do hike. I can't wait to do it again.

Nice hike from the road to the hot springs. Some great photos can be taken here. Get there early as parking is really limited and the hordes of people can make the trail unbearable. 8/13/16

Overall great easy hike. Cool thermal features, sweeping views of surrounding mountains and wildlife and enough of a challenge. Do it! Also go early and beat the crowd and heat.

Nice hike

Loved this hike! It has gorgeous wildflowers and a plank walkway over the mud pots. Very interesting. To me, it was like a mini Yellowstone hike because of the colorful mud pots.

Don't make a bumpass!!!

Bumpass Hell is a relatively easy hike. For this reason, it is wise to arrive early, as parking is limited and this trail does get quite crowded. The hike down to the geothermal hot springs is a bit steep, but not too difficult. Overall a very enjoyable short hike, beautiful and fun. I think it's worth doing at least once.
