Lava River Cave

Absolutely fantastic! There is about 180 steps to go down into the lava cave and about a mile walk in and a mile walk back out. It is really fantastic to see how mother nature formed this lava tunnel and all the features inside! Be sure to make your reservations online for your arrival time. Wear heavy close to keep warm and good shoes to hike with. And definitely good flashlights. There are good rentals there for $5.

Such a fun adventure, we'd want to visit again. The cool air in the cave and the need for navigating with light was really memorable. So grateful that everything is cleaned and maintained so well inside the cave.

Very cool experience. You only need timed tickets for parking and then you can pay for the national park pass there or use the America The Beautiful pass if you have one. Highly recommend spending the $5 for their spotlight.

This cave was awesome to see. it's worth it. you well need a flashlight and good shoes. definitely rent their flashlights.

Really fun to go on a hot day! You get in there and it’s at least 40 degrees. Super dark bring a light of some sort. (Phone battery may die if that’s your only light). Some spot are tall and open, perfect for trying out the vocals:))

Super cool lava cave - it's cavernous inside, so don't worry about claustrophobia. It's quite cold, so dress accordingly. Great for families too

Definitely a fun place to visit, but we didn't expect it's this big and so long under there... a few suggestions: 1. A flashlight is a must, and you better rent the $5 one from them, you won't regret it. Cellphone flashlight would work, but it's really weak inside there. It's totally dark down there. 2. Grab or bring a thick cloth(like a jacket) with you, you will need it, it is kind of cold inside and you might stay there a while. 3. The tube is very long and well maintained, big and clean, but still be careful when walking inside, don't fell. You could get hurt if you are not careful. You can walk for a long while, like about a 1 mile inside(and still it's not the end!) It doesn't look like that long from outside, you can't even tell it's such a big cave. Or you can walk a little then go back. 4. What's interesting inside? Well, depending on people. Some might spend hours to explore inside, some might just feel boring right away. We enjoyed it to hike inside and explore around. One more thing, you need to reserve it online to get into it. You can do it right at the park if there is still open spots available. I really hate this because the cell signal is not good there, and to force people using the online reservation($2 extra too). There is no ticket sale booth on site, unlike many other places.

A great place and experience. The cave is amazing and kept clean. There are also metal steps and pathways over the dangerous areas. Obviously, flashlights recommend. That said, a phone light for each person and a $5 rental light works plenty well. If you do bring your own lights I personally like flood light style over spot light, or one each. Boots instead of shoes recommend for rough areas, but your done either way. Cold inside, 42 degrees. Pants and jacket recommend.
