Getting There

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.

- Summer through fall is the best time to experience this trail. Snow covers the Lassen landscape for much of the year, closing roads and obscuring trails. See our links below to National Park Service information on road and trail closures. - Combine this hike with the 5-mile trek to the summit of nearby Lassen Peak for a great day out.

Directions from Southwest Entrance: Drive northward on Lassen Park Road 9 miles to the trailhead for Bumpass Hell.

10/10 recommend this hike. It is breathtaking and a good workout on the way back. Took us 3 hours including stopping for lunch.

08/12/2020 Very fun and nice trail. The bumpass trail was about 1.5 miles in and the cold boiling lake was 2 miles more. If you hike to cold boiling lake then it is definitely a moderately strenuous hike. Passed by some people who were maintaining the trail (Thank You!). It is very rocky and you have to pass by a few muddy areas. We started our hike at 8:30am and there were only a few groups. Finished in about 3.5 hours at 12pm and it was very crowded, no room in the parking lot and passed lots of families. Most people wore masks so that's great, thank you everyone. Overall, very fun hike with a good workout!

HikingGreat!

Sulfur pits were really cool! Trail is very well maintained, and Lake Helen parking worked great. You have the option to go on another 2 miles to the “cold-boiling lake”, but we were glad we didn’t after later going from a closer trailhead — not as impressive. Pretty crowded with decent mask adherence.

Going down to Cold Boiling Lake is a preface to the moderate climb out. Even though this trail is listed as Easy it’s probably more moderate if you go all the way down. Great weather today in August and the cold boiling pond was lackluster.

Did this trail on 8/2. Got there at 3pm and there were a few parking spots left. We had a 4 year old and 1 year old with us. I carried the younger kid in a pack the whole way and the 4 year old walked about 1/2 way to the destination before wanting to be carried. There are places where kids could fall off the trail but we saw plenty of kids of all ages on the hike. I would say if you are used to hiking then the easy rating is appropriate. If you rarely hike then moderate is more fitting. We did it in an hour and 45 minutes. It was a really cool hike. Definitely something worth seeing!!

The rating for this hike on Alltrails is “easy”, but I would say it was more “moderate” as it is pretty steep on the way back up. Also, there are several areas where you would be toast if you stumbled over the side. The views are truly gorgeous though. The majority of folks wore masks when we were there yesterday (Monday), but definitely not all.

Was out here about 2 weeks ago. The first section down to the boardwalk is an easy walk without too much effort. The next few miles out to the lake are all downhill which is nice until you realize you have to come back up. In high temps this is just a bit less than fun. Honestly, the cold bubbling lake isn't really worth the extra few miles so I'd say don't even bother. The best part is the area right around the boardwalk.

This is a great trail with easy visibility in the summer months. We were able to spot mountain grouse and a wide variety of other wildlife, and the fields of wildflowers along the trail were in full bloom. By the time we left the trail at 10am there was no parking and even the roadside was packed with cars. Come early!

This trail is great, but like everyone is saying I would put it more on the moderate side for the trip back. Be prepared to be on a crowded trail for the first half, and only about 50% of people are wearing masks. The trail is rather narrow, so it’s just something to keep in mind. All that said, this place is beautiful. I’ll definitely be back to explore the whole park some day.

Easy first half with barely any gain along a shaded trail. Second half picks up with more elevation change and highly reflective rock without much shade. Bring water, and the mask comes in handy not only for covid but for that delightful sulfur smell.

This was a spectacular hike! I agree with the other reviewers that it is more MODERATE than easy. My kids ages 12, 9, and 7 were able to do it with minimal whining, but they’re also used to hiking at higher elevations. The views were incredible the entire way. There is little shade and you’d be screwed if you fell off the edge of the trail in some parts (but this is also what grants unobstructed views). We really enjoyed everything about this hike.

Great!Rocky

Took this trail with another family. We had a 6yo, 10yo & 11yo with us. We brought our camalbacks and snacks for the kiddos to eat once we reached Cold Boiling Lake. The trail is well traveled and easy to follow. There are definitely some narrow sections where it can be tight when passing other hiking groups so we brought our masks to wear just when passing others. Go early, we arrived @7am on a Thursady and we practically had the park to ourself. However, by the time we hiked back to the parking lot at 12:30 there were tons of people, so much so that the parking lot was packed out.

Hiking

This definitely isn’t an easy trail, but nonetheless it is absolutely worth the hike. It has amazing views the entire time, and there are so many different things to stop and look at. If you have anything that makes hiking a little more difficult, being a trekking stick, because you will need it going back up the hill out of the sulfur mud pot area. It isn’t dog friendly with good reason. There are so many areas where a dog could get badly injured, and children as well. I highly recommend it if you have the time!

More like Bumpass *Heaven*! I "can't even" with how lovely this hike was on a crisp Monday morning at 8:30 am before the crowds arrived. Take the Frying Pan route down to fully appreciate the descending view of the springs, and the other route on the way up for views of colorful rocks and flowers.

This is NOT kids friendly and NOT easy trail. We start from Cold Boiling Lake. The trail is uphill, partially in a shadow. You have to go uphill very high - the trail is very narrow and rocky and dangerous in some parts. Beautiful views but with kids I recommend to go first to the Kings Creek Picnic Area and hike just to Cold Boiling Lake and back and then go to the Bumpass Trailhead Parking and go to the Bumpass Hell. The trail from Bumpass Hell to Cold Boiling Lake is very hard and dengerous and not for kids (as I wrote in the beginning - rocky, narrow, very high, very steep slope).
