a nice moderate level hike, and then "boom" you turn the corner and you are there! Very unique and cool with sulfer smells, bubbling heat from the ground, geysers with steam billowing out. Recommend reading the info sign about how it was named, so very interesting.

This is a 3-mile out-and-back trail that leads to the largest hydrothermal area in the park. It’s kind of a ‘must-do’ when you’re at Lassen, along with the hike to Kings Creek Falls. In general it’s a pretty easy hike, rising gently about 200 feet in elevation and then more steeply down another 200 feet to a basin containing the boardwalk that winds through the hydrothermal area. You can then amble along the boardwalk admiring the steaming vents and boiling pools before heading back to the trail head. The trail up from the parking lot is particularly pretty because of the scenic mountain views as you climb, but there are steep drop offs here, so be careful if you’re hiking with kids. Even though Bumpass Hell is more well-known I would say that the Devil’s Kitchen hike and hydrothermal area are just as good, and both are better and easier than the hike to Kings Creek Falls, which is rather steep. Some quick tips: the parking lot is small, so try to go early or on a weekday; it was completely full on a Sunday afternoon in September. Or alternatively, park at Lake Helen and take the trail from there. There are pit toilets in the parking lot. For a different view of the whole boardwalk area and especially the bubbling lake at the end, continue hiking past the boardwalk and climb the hill on the other side, then look back down at the volcanic activity. Finally, be sure to take the “Frying Pan” trail detour on the way back to the trailhead for a totally different view.

I think this is a Top 3 site to see in Lassen, along with Kings Creek Trail and Lassen Peak Tips for the Trail: 1. The Bumpass Hell parking lot gets crowded due to do the popularity of this trail (I would guess it is the most frequented out of all trails at Lassen). If you are visiting Lake Helen, you can park there instead and meet up with the Bumpass Hell trail across the street. It’s a shortcut as well! 2. If you are coming from the Bumpass Hell parking area, the trail splits into two once you get closer to the hydrothermal area, into the Frying Pan trail and Bumpass Trail. Take the Frying Pan alternative—it’s shorter and has closer views to the hydrothermal area as you approach. 3. In the summer, some of the mudpots were dry, however, you could see into a big one from the top of the peak, a bit after the boardwalks end. Temper expectations a bit, as the boardwalk is not as long as it is in some of the pictures posted a while ago. I’m only now looking at some of the TripAdvisor reviews from a while ago that looked different from my trip. It’s also smaller than the vast similar hydrothermal areas in Yellowstone, but it’s nice that they are in a very compact area, and always interesting to learn about how they formed.

Bumpass Hell is a fabulous otherworldly place in Lassen Volcanic NP. We took the longer more scenic route to Bumpass Hell via Cold Boiling Lake. This route, while more strenuous, really wasn't that terribly difficult for us moderate hikers. There were a few small waterfalls and muddy spots to cross, but nothing crazy. Cold Boiling Lake is a unique little spot in its own right, though from a distance away you wouldn't know it. The bubbles coming up from vents underground are in the marshy areas just south/west of the lake itself. The views of Crumbaugh Lake below you along the trail are some of the best in the park, IMO. It's a pretty steady climb from Cold Boiling Lake and I would think even school-age children could hike this pretty easily. Another perk is this route is not nearly as busy as the main route into Bumpass Hell. On our return to the Kings Creek Picnic Area trailhead, we did the short spur trail to Crumbaugh Lake from Cold Boiling Lake. While it was quiet and nice at the lake, the views of the lake were much better from above and the lake itself is a bit marshy and buggy. In the end, having now hiked to Bumpass Hell both ways, this is the way I would recommend doing it every time if I had the chance, unless I was short on time.

We took the trail from King’s Creek as the other trail was closed due to snow. Was a moderate trek up to destination as there was a decent amount of snow spots to traverse on and 2 small waterfalls to go over. Mostly in shade during the hike. We did not have hiking poles but would have been useful as well as hiking boots. Thermal area with mud pots at the top was a site I’ve never seen and worth the effort to get there.
