Quick little hike into a fantastic lava tube! Plenty of area in the pitch black. I did this alone and was lucky to be the only one in the cave. Super easy to get around (no debris or rocks to hike through or over), but the floor is a bit uneven, so keep some light lowered as you go and dont get too confident in the dark. Make sure you explore all the alcoves and keep heading back to the actual exit. Great fun, free, and so so easy!!

Great short hike! While not located in the NP, it’s worth the drive to see this unique hike! It’s a lava tube and pitch black dark once you get inside. If you have a head torch you will be fine just watch your steps as the ground is very uneven. Once out the other side you can walk around more trail above ground before going back down and through to the parking area.
Hiked on Thursday 9/6/18.

I would love to find those responsible for spray painting the walls. they should serve jail time. the hike is easy and short.

We often bring friends and family, especially kids. At 6'2" I will bump my head on the ceiling in places, and. looking up you'll trip on nobby places on floor. The entire walk is slower than the milage indicates and outside part hot and dry in summer, carry water if you bring kids.

A great family hike, lots of interesting stuff for the kiddoes, the PRNS museum is a real place. Not a brisk hike, but s great place to start your day.

Interesting cave. Rough ground to walk on. Be sure to have a good light source. We can check it off our bucket list.

Nice hike from the road to the hot springs. Some great photos can be taken here. Get there early as parking is really limited and the hordes of people can make the trail unbearable.

awesome area , will be accessible again soon ..

Excellent. Previous reviews say it well. Note: your smart phone flashlight will NOT suffice (unless you like running the risk of stubbing your toes or tripping). Note regarding dogs: a previous reviewer cautioned dog owners regarding tender paws and lava rock. Here's my point of view: if your dog primarily hangs out in the house or on a backyard lawn then you may want to be careful about taking your dog through. The lava rock underfoot is dirt and mud covered, but it does poke out in multiple places and could hurt a tender paw. If your dog regularly walks or hikes with you on varied terrain including cement, gravel, rocks, etc. and you take reasonable precautions about which path your furry friend takes in the cave, you should be fine. My husky walks and hikes frequently; his paw pads had no problem with the cave floor.

What an awesome experience. Bring your flashlights or you won’t make it through!! A short walk up well established steps leads you right to the opening of the cave. Within minutes you are inside the lava tubes. We went early in the morning after a rainstorm and could see water crystals on the roof of the lava tubes. Easy enough for kids but hold their hands because of the rough rocky ground. Definitely a must stop if in the area

Short trail very dark inside bring flashlight and good shoes i would not bring a dog sharp lava beds on floor in many aread2

The children and I love this dark hike through the lava tube! Everyone did well with their own headlamps, as the floor is quite uneven.

Did this in 2016. Had to take an alternative route as the main trail was closed for renovations

The name says it all

Very easy hike. Amazing how dark it is inside. I love introducing people to the cave.

Great little easy hike right by the visitors center. Decided to do it to get a bit of a stretch after driving from Reno before going on to explore more of Pt. Reyes. Has some nice interpretive signs and feels quite deep in the woods for being so close to the visitor center. It was a great short hike that my 2 year old son easily did all by himself.

Enjoyable hike / walk with minor elevation changes and an amazing view of the valley. Highly recommended for families and hikes of all ages.

A well-marked trail that offers beautiful views, varied terrain and a good opportunity to see the geothermal vents.

My husband and I hiked Bumpass Hell in August with our boys ages 10 and 13. It was a great out and back hike with views along the way and a great reward of the cool Bumpass Hell area. Bring water. There are bathrooms at the trail parking lot. We added the hike to Cold Boiling Lake which starts at the Bumpass Hell area.

Very windy and very chilly! Start this hike early! We were fighting with daylight on the way back- but it was unlike anything we'd seen before. Cool views! It's harder to breathe at this elevation.

A unique trail and a great taste of what Lassen Volcanic has to offer! Great views the whole way through. Be careful on the edges! ;-)

I did this in the snow in July and it was so slippery even with micro spikes! I'd recommend also having hiking poles if you go in the snow. Super easy and rewarding otherwise. Highly recommended.

My husband & I did this last Sat and it was beautiful. The weather was nice with a crisp cool air and the sun was shining. It was our first time in Lassen Park and we were very pleased with the surrounding beauty. Seeing the sulfur pools was amazing, we did this adventure in one day and then had a 3 hour drive home. We will definitely be coming back as we want to see the subway caves & painted dunes.

The first part of this trail is really easy to do for everyone. The second part it's even easier to do because it is a downward path that takes you to the pools of sulfur and the walkways that keep you safe from the unstable ground in some areas. There are some photo ops and those may vary from day to day, not always you get the spectacular bubbling that you expect. The return hike may be difficult to do as the first part is steep but it's a good hike nonetheless.

Absolutely gorgeous trail fairly straightforward and well marked. We went on to cold boiling lake trail despite thunder and lightning and we're especially thankful for the excellent trail markings when we returned to the entrance as over an inch of snow had accumulated. Spectacular views. We communed with two deer families along the way.

Harder than easy, easier than moderate. A great introductory trail to get to know Lassen. Roof of California. Loved it.

Very easy hike, would say it's more of a tourist attraction but cool nonetheless.
