This is a must do trail in Lassen Volcanic NP.

This is a 1.5 mile loop trail which is fairly easy and flat except for the final decent down into Bumpass Hell. As you come around the corner you start to get glimpses of the boardwalk and the steam but the smell hits you first! The boardwalk is well laid out and is reasonably quiet enabling you to admire the area and take photos without too many people in them, if at all.

The views along the trail are amazing as well. Lake Helen was so clean clear and bright.

This area is like a little tiny Yellowstone.

As other reviewers have noted Bumpass Hell doesn't open until early July. However, we were there June 22, 2013 and they just opened the trail from Kings Creek to Bumpass Hell. This trail tends to get more sun and opens a little earlier than the main trail. However, it is a 6 mile roundtrip as opposed to 3 miles and is moderately difficult as opposed to easy. Going from Kings Creek to Bumpass Hell is about a 1,000 ft rise. Another option is to hike all the way from Bumpass Hell to Kings Creek campground (as long as you have a ride back to the start. Going from Kings Creek to Bumpass is uphill, but going from Bumpass down to Kings Creek is mostly down). From Kings Creek it is a beautiful trail that first passes Cold Boiling Lake where cold gases from within the ground come up into the lake causing it to look as if it is boiling. Then the trail rises up the side of Bumpass mountain about 1,000 feet crossing a number of small streams flowing out of snow banks as well as a number of different floral areas from large tree groves to small sections of specific plants and flowers. The trail reveals grand vistas of the southern end of the park as well as of Lassen National Forest which are really stunning. Finally, we were rewarded as we entered the odd world Bumpass Hell and it's many geothermal wonders. It was a really crazy transition from green forests and pure streams of the mountain to the odd colors and acidic flows of Bumpass. Really worth the effort but it was about a 3.5 hour round trip. If you are short on time take the regular trail, but this trail has less people and is really rewarding for a moderate hike.

Just a warning to those planning to visit Lassen Volcanic Park - the main attraction is the Bumpus Hell hike, which doesn't open until all the snow and ice has melted from the trail, usually the first week of July. We visited the park June 17 and the trail was a couple of weeks from opening. It looked amazing and I'm sorry we missed it. The rest of the park is pretty and there are certainly other things to see, but I wouldn't travel there again without checking to make sure the Bumpus Hell trail was open.

This was the first stop for my son (14) and I on our 20-day road trip out west. I drove 2 16-hour days to reach Lassen and we started with this trail the next morning. The trail is fairly easy (little elevation gain/loss) though still had snow in several locations that could make for slick footing. I'd estimate 20-30 minutes to reach the area depending on snow levels.

The geothermal area itself on the other side of the ridge was pretty neat though obviously not as spectacular as the more extensive Yellowstone areas. There are several fumeroles, mud pots and springs and there was some nice coloring for those that like photography. Please do stay on the boardwalks. Plenty of people have been burned over the years, including the area's namesake, by breaking through the thin upper crust. A woman had to be airlifted just a month prior to our visit. The hike back would be the most difficult part of this simple dayhike with a little over 200' elevation gain to reach the ridgeline but shouldn't be a concern unless slushy/muddy and you're not wearing appropriate footwear.

Even though Lassen is not a frequently visited location, the parking areas can fill up by lunch. We started about 10 am on July 3 with plenty of space in the lot, and it was full when we returned at 11:40.

You could extend the hike to Cold Boiling Lake, but if you wish to see that it would be easier from Kings Creek Campground.

This is a place I remember from trips with my parents 40 years ago. It doesn't fail to delight now. I took friends with 12 year old kids, and they were thrilled by the sulfur works (complete with rotten egg smell-part of a hydrothermic area experience) and the fairly easy hike.
