What Travellers Say
Reviews Summary
Visitors rave about Bumpass Hell's otherworldly landscapes, comparing it to Yellowstone with its bubbling mud pots and steaming fumaroles. The unique geothermal activity and the well-maintained boardwalks are frequently praised. However, some find the sulfur smell strong, and the trail's seasonal accessibility can be a point of frustration if not checked in advance.
"This has to be the most popular hike in Lassen Volcanic National Park by far. We got here around 3pm the Sunday of Labor Day weekend on our way out of the park after summiting Lassen Peak. There were cars parked along the road for almost a quarter mile, so we found a spot next to Helen lake on a slightly sketchy incline, and found a connector trail to the actual Bumpass trail. It was absolutely packed with people, with very few chances to pick up the pace. You have to ascend around 200 feet in a mile before you start seeing any thermal activity. Once there, the hot springs are well worth spending some time at. Constantly fuming geysers make for some great videos. There is a nice boardwalk going right through them. The smell of sulphur is omnipresent."

"Bumpass Hell is a fantastic hike with good thermal activity. The hike is at high elevation so the trail usually doesn’t open until July (sometimes as late as August) and closes late October early November due to snow. Make sure to check the trail status before you leave if you really have your heart set on hiking Bumpass Hell. Otherwise there are other good trails in Lassen Volcanic National Park to hike."

"Reminds me of Yellowstone! So beautiful! Love the hike in and the hike back is great! We decided to run the way back and what a fun and quick way to end the hike! The purple flowered hill is beautiful with sweet surprises underneath the flower grove."
