An amazing walk through an other-worldly geothermal field of steam, bubbling cauldrons and spitting holes. No matter which direction you turn, you will be enchanted and amazed!

The short hike to Bumpass Hell is closed right now - Oct/Nov '18. You can still get there via the long hike with great views from the King's Creek Campground. Still worth it.

Bumpass Hell is one of my favorite spots in Lassen National Park, and in all of Northern California. I live in the area and any time someone visits me, I try to take them here. Unfortunately it is often closed until late in the summer...More

This was an amazing place to visit. We went there in August, the height of summer. Because Lassen Park is so high, we noted the beginnings and then the coverage of snow. Bumpass Hell is a volcanic park with hot springs but even in summer...More

We were bummed because we booked our trip in January but the trail was closed in the spring. It will be closed for the rest of 2018 but the rest of the park is amazing.

Bumpass Hell is closed to the public for the 2018 and 2019 seasons. They are reconstructing the raised boardwalk for safety reasons. Although there is no real replacement for Bumpass, check the Lassen website for some alternatives.

No. Bring a carrier if you have a baby / toddler. Trail may be challenging for young kids. But definitely worth it!

We will be traveling to Lassen Volcanic NP tomorrow from Weaverville CA on 299. We know nothing about the place so I think it is important that we go to the visitor’s center before beginning the day. Should we take 299 to 5 to 36 to enter to the south? Is there anything I need to know about visiting there? I do know that Bumpass Hell Trail is closed for the season. We are an upper-60s couple in decent shape that look for easy to moderate hikes of 4 - 5 miles with no part of the trail...More

Going solo to Lassen Volcanic Ntl Park in early November (11 Replies)
Hello everyone. I touch down in Oakland and have about 4 days to explore Lassen and the surrounding areas (redwood forest, coast, etc). I definitely want to climb Lassen Peak, visit Bumpass Hell, Cinder Cone, and maybe the Subway Cave. First of all, how much time I should set aside for Lassen? Secondly, how do I do this cheaply? I am prepared to car camp if possible. Is the weather to cold at this time of the year to do so? Are there any no fee camp sites I should know about? ...More

November starts Sunday. So the weather forecast is http://www.weather.com/weather/tenday/l/Lassen+Volcanic+National+Park+CANPLV:13:US It also gives you the temperature ranges - to me its too cold to car camp. Chester is a town to the South you night consider staying in. Or to the North Burney or Hat Creek Area, Or be sure you have a sleeping bag for colder weather - see the forecast for predicted temperatures. You can see Lassen Volcanic National Park in a better part of a day. If you...More

4th of July, any doable day hike trails suggested? (2 Replies)
Hi all, Planned the trip during the 4th of July holiday, wondering if there any trails recommendations for current condition? The Lassen peak trail is open but at peak the NPS website says ~10feet snow, we only have snow traction cleats, I doubt if that's enough. Base on what I know, Bumpass hell most likely will remain closed. Crags lake seems cool? We are coming from Redwoods Parks, maybe we should plan more time over there? Thanks in advance!

I'm not even entirely certain the main park road through Lassen will be open by July 4th. However, what you certainly could do is hike the Cinder Cone Loop from Butte Lake. The road to Butte Lake is located off CA 44 in the NE section of the park. The trail should be in good shape by the time you arrive. That is a great early season hike. You will have great views at the top of Cinder Cone and be able to see Lassen Peak, the Fantastic Lava Beds and the Painted Dunes.
